The servicing information contained in these operating instructions is intended only for the use of qualified service engineers. An electric shock can be fatal. Do not carry out any actions other than those described in the documentation. This also applies to qualified personnel.
All cables and leads must be secured, undamaged, insulated and adequately dimensioned. Loose connections, scorched, damaged or inadequately dimensioned cables and leads must be immediately repaired by authorised personnel.
Maintenance and repair work must only be carried out by an authorised specialist.
It is impossible to guarantee that bought-in parts are designed and manufactured to meet the demands made on them, or that they satisfy safety requirements. Use only original spare parts (also applies to standard parts).
Do not carry out any alterations, installations, or modifications to the device without first obtaining the manufacturer’s permission.
Components that are not in perfect condition must be changed immediately.

Noise emission values

The maximum sound power level of the inverter is specified in the Technical Data.
The device is cooled as quietly as possible with the aid of an electronic temperature control system; this depends on the amount of converted power, the ambient temperature, the level of soiling of the device, etc.
It is not possible to provide a workplace-related emission value for this device because the actual sound pressure level is heavily influenced by the installation situation, the power quality, the surrounding walls and the properties of the room in general.

EMC measures

In certain cases, even though a device complies with the standard limit values for emissions, it may affect the application area for which it was designed (e.g., when there is equipment that is susceptible to interference at the same location, or if the site where the device is installed is close to either radio or television receivers). If this is the case, then the operator is obliged to take action to rectify the situation.

Fronius Symo Hybrid
Device concept

Device design:
(1) Housing cover (2) Inverter (3) Mounting bracket (4) Connection area including DC
main switch (5) Data communication area (6) Data communication cover

The hybrid inverter converts the direct current generated by the PV modules into alternating current. This alternating current is synchronized with the grid voltage and fed into the public grid. Moreover, the solar energy can also be stored in a connected battery for later use.
The hybrid inverter has been developed specifically for use in grid-connected photovoltaic systems. A backup power mode is possible if the cabling is set up accordingly.
Thanks to its design and operating principle, the inverter is extremely safe both to install and to operate. The inverter monitors the public grid automatically. In the event of abnormal grid conditions, the inverter ceases operating immediately and stops feeding power into the grid (e.g. if the grid is switched off, if there is an interruption, etc.). The grid is monitored by monitoring the voltage, frequency and islanding conditions. The inverter switches to backup power mode if it has been cabled up accordingly.
Operation of the inverter is fully automatic. The inverter is designed to draw as much power from the PV modules as possible. Depending on the operating point, this power is either stored in the battery, fed into the grid or used for the household network in backup power mode.
As soon as the energy provided by the PV modules is no longer sufficient, the power from the battery is fed into the home. Depending on the setting, power may also be obtained from the public grid in order to charge the battery.
If the inverter becomes too hot, it automatically reduces the current output power or charging power, or switches to backup power mode in order to protect itself. Reasons for the inverter becoming too hot include the ambient temperature being too high or inadequate heat dissipation (e.g. if it is installed in a switch cabinet without suitable heat dissipation).
IMPORTANT! The battery must only be switched on when the inverter is in Standby mode.
13

Proper use

The solar inverter is exclusively intended for charging a battery with direct current from solar modules, or for converting this direct current into alternating current and feeding it into the public grid or the household network in emergency power mode. The following actions constitute improper use: – Any use above and beyond this purpose – Making any modifications to the inverter that have not been expressly ap-
proved by Fronius – Installing components that are not distributed or expressly approved by
Fronius – Operating the device with a battery that has not been approved by Fronius – Operating the equipment with an energy meter that has not been approved
by Fronius
Fronius shall not be liable for any damage resulting from such action. No warranty claims will be entertained.
Proper use also includes: – Carefully studying and obeying the Installation and Operating Instructions – Performing all stipulated inspection and maintenance work
When designing the photovoltaic system, ensure that all of its components are operated within their permitted operating ranges at all times.
Observe all the measures recommended by the solar module manufacturer to ensure that the solar module retains its properties in the long term.
Observe the stipulations of the power supply company concerning energy fed into the grid, emergency power mode and the operation of storage systems.
The Fronius Symo Hybrid is a grid-connected inverter with an emergency power function it is not a stand-alone inverter. The following restrictions must therefore be observed in emergency power mode: – Emergency power mode may be in operation for at least 1500 hours – Emergency power mode may be in operation for more than 1500 operating
hours if 15% of the duration of the inverter’s grid power feed operation is not exceeded at the relevant time

Proper use

With the market launch of its new Fronius Energy Package, Fronius is introducing an inverter that can be used to store energy. One of the key components is the Fronius Solar Battery, which contains a lithium-ion rechargeable cell. The Fronius Solar Battery supplements the Fronius hybrid inverter by adding storage functionality. This means that the solar energy from the solar modules can be stored for later use. The storage system is only suitable for operation in conjunction with Fronius hybrid inverters.
Thanks to its design and operating principle, the storage system is extremely safe both to install and to operate. A high-performance lithium-ion phosphate battery is used (LiFePO4), which is based on the latest technology and complies with the highest safety standards.
When used in conjunction with the Fronius inverter, operation of the storage system is fully automatic.
If proper charging of the batteries in the Fronius Energy Package cannot be guaranteed for an extended period of time (over several weeks or months) for any reason, we strongly recommend that the following steps are undertaken to prevent the deep discharge of the battery modules: – switch off the main switch of the Fronius Solar Battery – remove the DC fuses from the fuse holder – remove the orange power connector from the individual battery modules
The Fronius Solar Battery is exclusively intended for taking direct current from a Fronius hybrid inverter and storing it for later use. The following actions constitute improper use: – Any use above and beyond this purpose – Making any modifications to the storage system that have not been expressly
approved by Fronius – Installing components that are not distributed or expressly approved by
Fronius – Operating the system with an inverter that has not been approved by Fronius – Operating the equipment with an energy meter that has not been approved
by Fronius

Fronius shall not be liable for any damage resulting from such action. No warranty claims will be entertained.
Proper use also includes: – Carefully studying and obeying the installation and operating instructions – performing all stipulated inspection and maintenance work
Observe the stipulations of the power supply company concerning energy fed into the grid and the operation of storage systems.

Increase in storage capacity

The storage capacity of the Fronius Solar Battery can also be increased after purchase to a maximum capacity of 9.6 kWh of usable energy. The capacity is increased by adding additional battery modules and this must be carried out by a qualified electrician. Capacity can be expanded within 2 years from the date of purchase, but a maximum of 30 months following dispatch from Fronius Austria. The capacity cannot be increased after this for technical reasons. Observe the stipulations of the distribution network operator concerning energy fed into the grid and the operation of storage systems.

State of charge (SOC) accuracy

Adding or replacing a memory module can lead to inaccuracies when calculating the state of charge (SOC). Straight lines and jumps can occur, in particular immediately after the upgrade. These only affect the display of the state of charge and do not affect operation of the device.

The various operating modes

Operating modes Explanation of symbols

Solar module Generates direct current
Inverter Fronius hybrid Converts the direct current into alternating current and charges the battery. Thanks to the built-in system monitoring function, the inverter can be integrated into a network using WLAN technology.
Battery Connected to the inverter on the DC side and used to store electrical energy.
Photovoltaic system consumers The consumers connected to the PV system (single or threephase)
Meter Fronius Smart Meter For optimum energy management. You can have the meter installed in a switch cabinet by your electrical installer. Energy profiling is possible through the use of several Smart Meters. Additional consumers or generators in the system can be measured and monitored.
Emergency power function The inverter is delivered ready for supplying emergency power. However, the electrical installer must set up the emergency power function in the switch cabinet. In emergency power mode, the PV system operates as a stand-alone island.
Fronius Ohmpilot To use surplus energy to heat water.
Additional inverter in the system (e.g. Fronius Symo) Converts the direct current into alternating current. Cannot, however, be used to charge batteries and is not available to provide emergency power.

Operating mode: The Fronius hybrid inverter can be used purely as an inverter without a battery

Inverter

connected to it.

Operating mode – Inverter plus battery

To ensure fault-free regulation, parallel operation of several batteries is not permitted.
To optimise self-consumption in your PV system, you can use a battery as a storage system. The battery is connected to the inverter on the DC side. As a result, there is no need for multiple current conversion processes, which results in greater efficiency.

Operating mode – Inverter plus battery and multiple Smart Meters

Operating mode – inverter with battery, ACcoupled to another inverter

Operating mode – Inverter plus battery and emergency power function

IMPORTANT! In emergency power mode, an increased nominal frequency is used in order to avoid parallel operation with other generators.
To ensure fault-free regulation, parallel operation of several batteries is not permitted.
When the hybrid PV system is equipped with all the available features, the inverter can: – Feed energy into the grid – Supply the devices that are connected to the PV system with power in the
event of a power failure – Use any excess energy to charge the battery.

Operating mode – Inverter plus battery, Ohmpilot and emergency power function

IMPORTANT! In a hybrid PV system with Fronius Ohmpilot and all the system features, the Ohmpilot cannot be operated in the event of a power failure for control-related reasons. Therefore, it makes sense to install the Ohmpilot outside of the emergency power circuit.

Operating mode – Inverter plus battery, additional inverter and emergency power function

The Fronius Symo Hybrid recharges the battery to counteract self discharge and maintain the set minimum SOC (protection against deep discharge).
The battery has reached the set minimum SOC. The battery cannot be discharged further until charging takes place again.
The system has been put into energy saving mode. None of the LEDs or the battery display light up1). Energy saving mode is automatically ended as soon as sufficient excess energy is available again.
The system is in calibration mode. When there is insufficient PV energy available to reach 100%, the battery is cyclically charged to 100% for internal calibration. Under certain conditions (depending on weather, microcycles, temperature, etc.), this can take an extended period of time.

Emergency power mode

Prerequisites for emergency power mode

In order to use the hybrid inverter’s emergency power function, the following
prerequisites must be fulfilled:
– Correct cabling of the emergency power system in the electrical installation (see document “Fronius Energy Package – Examples of emergency power
switchover”).
– The Fronius Smart Meter must be installed at the feed-in point and configured.
– Latest firmware on the inverter – if required, perform a firmware update. – The emergency power sticker provided with the inverter must be attached to
the electrical distributor.
– Select Alternative (emergency power) setup in the CONFIG menu on the inverter (see Installation Instructions).
– Change the required settings in the emergency power area in the IO mapping menu (Fronius system monitoring web page Settings IO mapping
Emergency power).
– Set the emergency power to “Auto” in the system overview (Fronius system monitoring web page Settings System overview Emergency power op-
erating mode).

If there are additional inverters in the system, these should be installed outside of the emergency power circuit, but within that for the Fronius Smart Meter, see Operating mode – Inverter plus battery, additional inverter and emergency power function on page 24.

NOTE! Emergency power mode is not possible with the batteries from the LG Chem ResuH series.

Transitioning from feeding energy into the grid to backup power mode

1. The public grid is monitored by the inverter’s internal grid and system protection unit and by the Fronius Smart Meter connected to it.
2. The public grid fails or specific grid parameters are dropped below or exceeded.
3. The inverter carries out the measures necessary according to the country standard and then switches off.
4. The inverter starts backup power mode after a checking period. 5. All loads in the household that are in the backup power circuit are supplied
by the battery and the PV modules. The remaining loads are not supplied
with power and are safely isolated.

Transitioning from backup power mode to feeding energy into the grid

1. The inverter is operating in backup power mode. 2. The public grid is functioning correctly again. 3. The Fronius Smart Meter monitors the grid parameters on the public grid
and passes this information to the inverter.
4. The stability of the returned public grid is determined by checking the measured values of the Fronius Smart Meter.
5. The inverter ends backup power mode. 6. All circuits are reconnected to the public grid and are supplied by the grid. 7. The inverter can start feeding energy into the grid again after performing the
grid checks required by the relevant standard.

Restrictions in backup power mode

In backup power mode, some electrical appliances cannot function properly as the starting currents are too high (e.g. fridges and freezers). It is recommended to switch off non-essential loads during backup power mode.
Switching from grid-connected operation to backup power mode takes a little while. For this reason, the battery system with backup power function cannot be used as an uninterruptible power supply, for example for computers.
If no energy is available from the battery or the PV modules during backup power mode, this mode is automatically ended, irrespective of whether power is available from the public grid or not. Fronius Solar Battery: If sufficient energy becomes available from the PV modules once again, backup power mode starts again automatically. BYD Battery-Box Premium: The system must be restarted manually as soon as sufficient energy from the PV modules or the public grid is available again. For the correct power-up sequence, see chapter BYD Battery-Box Premium on page 34.
If consumption is too high, backup power mode is interrupted and status code “143 – Backup power overload” appears. The maximum power in backup power mode according to the technical data must be observed!

Backup power and energy saving mode

If the inverter is operating in backup power mode, energy saving mode is automatically active. Under the following conditions, the battery and the inverter are switched to energy saving mode after a waiting time of 8 – 12 minutes: – The battery is discharged to the minimum state of charge and no energy is
coming from the PV modules. – The inverter is in an error state that is not acknowledged automatically (e.g.
multiple overload). – The inverter is set to energy saving mode (standby mode) using the display
setting.
If the battery and inverter are in energy saving mode, the system is reactivated by the following actions (applies only for Fronius Solar Battery): – Enough energy is available from the PV modules. – The public grid is functioning again. – The battery’s POWER switch is switched off and on.
More information on energy saving mode can be found in chapter Energy saving mode on page 29

Fronius Ohmpilot and backup power mode

The Fronius Ohmpilot is not suitable for backup power mode. If a Fronius Ohmpilot is used, it should be installed outside of the backup power circuit (see Operating mode – Inverter plus battery, Ohmpilot and emergency power function on page 23).

NOTE!
Risk from an active Ohmpilot in backup power mode. This may result in loss of the backup power supply.
Never turn on boost mode on the Ohmpilot. Switch off the automatic circuit breaker on the Fronius Ohmpilot (if fitted). Before a power outage occurs, any function that would exceed the power
limits in backup power mode must be disabled.

Disable functions that would exceed the power limits in backup power mode: 1 Set measuring of heating rod to manual on the Ohmpilot (under “General –
General Settings – Heating 1 – Manual”). 2 Disable the “Legionella prevention (h)” and “Adapt day curve” settings (under
“General – General Settings – Heating 1”).

Energy saving mode

General

Energy saving mode (standby) is used to reduce the self-consumption of the system. It is available from version 1.4.1-11 of the system monitoring software. Both the inverter and the battery automatically switch into energy saving mode under certain conditions.
Fronius Symo Hybrid If the battery is flat and no PV energy is available, the inverter switches to energy saving mode. Only the inverter’s communication with the Fronius Smart Meter and Fronius Solar.web is maintained.
Fronius Solar Battery When the battery is in energy saving mode, the display remains dark. In Solar.web, energy saving mode is indicated by an “i” next to the battery symbol. In the energy balance view, the SOC (State of Charge) of the Fronius Solar Battery is not displayed for the duration of energy saving mode.
BYD Battery-Box Premium In Solar.web, energy saving mode is indicated by an “i” next to the battery symbol.

Fronius Solar Battery and Fronius Symo Hybrid switchoff conditions

The battery state of charge is less than or equal to the input minimum state of charge.
The power from the PV modules is less than 50 W.
The current charging or discharging power of the battery is less than 100 W.
Less than 50 W is available for charging the battery. The power of feeding in for the public grid is at least 50 W less than the power currently required in the home network.
If all the switch-off conditions are met, the battery switches into energy saving mode within six minutes. This time delay ensures that the inverter can be restarted at least once.
The inverter automatically switches into energy saving mode after the battery.
Backup power: If the backup power function has been activated, the battery in grid operation does not switch to energy saving mode. Otherwise, the dark start (start without grid and PV supply) of the hybrid system cannot be ensured. During backup power mode and when the state of charge falls below the minimum limit, the battery switches to energy saving mode.

Fronius Symo Hybrid and Fronius Solar Battery switchon conditions

If one of the following conditions is met for at least 30 seconds, energy saving
mode is ended:
– Energy saving mode is no longer permissible owing to a changed setting on the user interface of the inverter.
– More than 50 W is available for charging the battery. The power of feeding in for the public grid is at least 50 W greater than the power currently required
in the home network.
– If a dynamic power reduction of 0 is set, or if the system is operating in backup power mode, the power of feeding in for the public grid is always less
than the required power in the home network.
There is a separate condition for this case (dynamic power reduction < 300 W
or active backup power mode): If the PV power is above a specified threshold
(50 W), the energy saving mode is ended.
– Battery charging from the public grid is requested via the website. – The battery is recharged to restore the minimum state of charge or to per-
form a calibration.
– The Fronius Solar Battery is woken up as soon as the Symo Hybrid is generating PV power. This guarantees reliable operation of the battery.

Special case

If the inverter does not operate for 812 minutes (e.g.: error), or if there is an interruption in the electrical connection between the inverter and battery, the battery switches into energy saving mode in any case. This reduces self discharge of the battery.

Indicators on the devices and user interfaces

During energy saving mode:
– Orange status LED lights up steady – The inverter website can be accessed – All available data is saved and sent to Solar.web – The current available data can be viewed on Solar.web

Energy saving mode is shown on the website of the inverter and in Solar.web by an “i” beside the battery symbol in the system overview.

Calibration charging for the Fronius Solar Battery

Benefits of calibration charging

Natural differences in the individual cell capacities and the small amount of self discharge that occurs in all batteries cause the cell voltages to diverge. This makes the SOC value less accurate, which affects the operation. If no steps are taken, the battery will become damaged.

Periodic calibration charging brings all cells of the battery to the same state of charge, and calibrates the SOC value. This ensures a longer service life of the battery cells.

General

Determining the exact state of charge (SOC) of the battery is important for operation management. To ensure this happens, the battery must regularly be charged to 100%. This allows the SOC value to be calibrated.
Fronius Solar Battery: Calibration charging occurs automatically during operation after several charge and discharge cycles. When calibration charging is carried out depends on two crucial factors:
– Average state of charge – Energy throughput of the battery
As these factors are extremely weather dependent, the time of a calibration charge can vary depending on the time of year.
The following description of calibration charging is valid from version 1.4.1-12 of the Fronius system monitoring software.

Conditions for starting the calibration charge (Fronius Solar Battery)

One charge and discharge cycle of the Fronius Solar Battery corresponds to an energy throughput of 48 Ah per battery module. Calibration charging occurs cyclically according to the following conditions: – After 3 full charge and discharge cycles and a SOC of 80% – After 5 full charge and discharge cycles and a SOC of 50% – After 7 full charge and discharge cycles, independent of the SOC
For newly installed systems and for module replacement or expansion, a calibration charge is started automatically after 30 minutes.

Calibration charging procedure (Fronius Solar Battery)

Calibration charging primarily occurs with the entire PV power. If insufficient PV energy is available, energy is drawn from the public grid. This is also the case even if the “Battery charging from DNO grid” function is deactivated, as this is a critical requirement.

The SOC is calculated per battery module. For this reason, each battery module must reach a SOC of 100%.

Calibration process (Fronius Solar Battery)

1. The start conditions must be fulfilled 2. The battery is charged to 100% with a minimum current of 6.5 A or the total
PV power.
3. So that a SOC of 100% can be reached for each battery module, one of the following two conditions must be fulfilled for at least 2 minutes (for each cell
in every battery module):
– Minimum cell voltage ³ 3.45 V and current < 100 mA – Minimum cell voltage > 3.5 V independent of current 4. When a battery module reaches one of these conditions, the current is limited to prevent an overload. A current in the two-digit mA range flows over a
bypass resistor
5. Unneeded PV power is reused directly 6. Once all cells in all battery modules have fulfilled one of the two conditions,
the SOC is set to 100% and calibration charging is complete.

Duration of calibration charging (Fronius Solar Battery)

Due to tolerances in the cells, they are not always charged and discharged at the same rate. As cells and battery modules are connected in series and the slowest cell determines the charging and discharging duration, some calibration charges need more or less time.

In rare cases, calibration charges or full charge cycles (depending on the time of year, e.g. in the winter months) can lead to large variations in the cell voltages in the battery modules. In calibration mode, one cell charges more quickly than the others. This cell then begins redistribution. The other cells can then only be charged with a reduced charging current. It takes longer for these cells to reach the target value.

If the battery is regularly charged completely, calibration charges are rarely required. The cells are calibrated during every charge with 100% SOC. In the winter months. where there are few full charges and a lower energy throughput, calibration charges can take longer, as higher variations between the battery modules must be redistributed.

Limitations during calibration (Fronius Solar Battery)

– Drawing energy from the battery (discharging) is not possible – Self- consumption optimisation is disabled while calibration charging is in
progress
– Charging from the grid can still occur if the “Battery charging from DNO grid” function is not activated, as this process concerns system-relevant ser-
vice charging
– Zero feed-in continues according to the standard and service charging can even be started if you wish to expand or replace battery modules during cal-
ibration
– Emergency power mode can be started calibration charging is interrupted

Display during calibration charge (Fronius Solar Battery)

As soon as calibration charging starts, it becomes visible in Fronius Solar.web (current and energy balance view) or on the web interface of the Fronius Symo Hybrid inverter.

In Fronius Solar.web or on the web interface of the inverter, the calibration charge information is displayed in the overview. Clicking on the battery symbol (see the image on the left) displays the information “The battery is in calibration mode” In the energy balance display in Solar.web, both the start and end of the calibration charge is displayed by changing the battery status (“Battery Mode: Normal Calibrate” and “Battery Mode: Calibrate Normal”) The following graphic shows calibration charging of the Fronius Solar Battery in the energy balance view. At the start of calibration charging, the total PV production is used to charge the battery. From the point where one cell is fully charged, only a certain charging current is drawn by the battery. This charging current decreases towards 0 A as the cell voltage increases.
As during normal operation, the status “charging” (CHG) is shown on the battery display and the relevant charging current in ampere is displayed. If the charging current drops to below 0.3 A, 0 A is shown on the display, even though calibration charging continues. In Fronius Solar.web, the SOC value for the entire battery is displayed. On the battery display, the SOC values of the individual battery modules can be viewed.

Relay (floating contact switch)

Status codes (state codes), the status of the inverter (e.g. feeding energy into the grid) or Energy Manager functions can be displayed using the floating switch contact (relay).

Setting range

Relay mode / Relay test / Switch-on point / Switch-off point

these are only shown if the “E-Manager” function has been activated under “Relay mode”.

Relay mode
The following functions can be shown using relay mode:
– Alarm function (Permanent / ALL / GAF) – Active output (ON / OFF) – Energy Manager (E-Manager)

Setting range Factory setting

ALL / Permanent / GAF / OFF / ON / E-Manager ALL

Alarm function:

ALL / Permanent:

Switching the floating switch contact for permanent and temporary service codes (e.g. brief interruption to energy being fed into the grid, a service code occurs a certain number of times a day – can be adjusted in the “BASIC” menu)

GAF

As soon as GAF mode is selected, the relay is switched on. The relay opens as soon as the power stage set registers an error and goes from normally feeding energy into the grid to being in an error state. This means that the relay can be used for fail-safe functions.

Application example It may be necessary to perform phase compensation when using a single-phase inverter at a multiphase site. If an error occurs on one or several inverters and the connection to the grid is broken, the other inverters must also be disconnected to maintain the phase balance. The “GAF” relay function can be used in conjunction with the Datamanager or an external protection device to recognise or signal that an inverter is not feeding in or is disconnected from the grid and to then disconnect the remaining inverters from the grid using a telecontrol command.

Active output:

ON:

The floating NO contact is on all the time the inverter is in op-

eration (as long as the display is not dark or is displaying

something).

OFF:

The floating NO contact is off.

Energy Manager:

Switch-off point (only if “Energy Manager” function is activated) for setting the effective power limit beyond which the floating switch contact is switched off

Factory setting Setting range

500 0 to the set switch-on point of the inverter (W or kW)

Energy Manager (under “Relay” menu item)

The “Energy Manager” function can be used to activate the floating switch contact in such a way that it functions as an actuator. Thus, a load that is connected to the floating switch contact can be controlled by specifying a switch-on or switch-off point that depends on the power of feeding in.
The floating switch contact is automatically switched off: – If the inverter is not feeding any power into the grid – If the inverter is manually switched to Standby mode – If the effective power is set to < 10% of the rated power

To activate the “Energy Manager” function, select “E-Manager” and press the “Enter” key. When the “Energy Manager” function is running, the “Energy Manager” symbol will appear in the top left corner of the display:
When the floating NO contact is off (open contact)

When the floating NO contact is on (closed contact)

To deactivate the “Energy Manager” function, select a different function and press the “Enter” key.
Notes on setting up the switch-on and switch-off points The interface of the energy management relay always uses the output power of the inverter as a reference point, although this will not necessarily match what is generated by the PV system in the case of the hybrid system. If the difference between the switch-on and switch-off points is too small, or if there are fluctuations in effective power, the result may be multiple switching cycles To avoid frequent switching on and off, the difference between the switch-on and switch-off points should be at least 100 – 200 W.

When choosing the switch-off point, the power consumption of the connected load should be taken into account.
When choosing the switch-on point, the weather conditions and anticipated insolation should also be taken into account.
Application example Switch-on point = 2000 W, switch-off point = 1800 W
If the inverter is outputting 2000 W or above, then the floating switch contact on the inverter is switched on. If the inverter output falls to below 1800 W, the floating switch contact is switched off.
Possible applications: Operating a heat pump or an air-conditioning system using as much self-generated power as possible

General

Fronius system monitoring is a networked datalogger. The Fronius system monitoring web page provides a quick overview of the photovoltaic system. It can be accessed via a web browser when there is a direct connection or if configured to support an indirect connection over the Internet.
If the feature is used in conjunction with Fronius Solar.web, current data and archive data can be accessed for a particular photovoltaic system via the Internet or the Fronius Solar.web App without the need for any laborious configuration work. Fronius system monitoring automatically sends the data to Fronius Solar.web.

Prerequisites for operation

You must have a suitable internet connection to enable data to be exchanged smoothly over the internet: – For wired internet solutions, Fronius recommends a

download speed of at least 512 kBit/s and an

upload speed of at least 256 kBit/s.
– For solutions that rely on mobile internet services, Fronius recommends 3G transmission as a minimum, plus a reliable signal.

Even if these specifications are adhered to, there is still no guarantee that everything will run smoothly. High error rates during transmission, variable reception conditions or transmission dropouts can all have a detrimental effect on the online functionality of Fronius system monitoring. Fronius recommends testing any connections that meet the minimum requirements locally.

Calculating data volumes

General

When using Fronius system monitoring, data is collated that must be transmitted over the internet. The data volume must be calculated so that the correct internet connection is selected.
The data volume calculation below provides an overview of the data quantities involved when using Fronius system monitoring.

Calculating data volumes

The data volume calculation depends on the number of connected devices in the system monitoring. The table below provides an overview of the data volume for various configurations and time settings (INV = Fronius Symo Hybrid, SM = Smart Meter, BAT = battery module of the Fronius Solar Battery)

A data volume of approx. 500 kB per hour is required to view the system on Fronius Solar.web or the Fronius Solar.web App.
A certain data volume is also required to update the Fronius system monitoring firmware. This data volume depends on the size of the update package and therefore cannot be considered in the advance data volume calculation.
If data is sent via a third-party service (e.g. push service), a large quantity of data may be involved.
IMPORTANT! Fronius recommends a flat rate data connection to avoid high connection charges.

General information for the network administrator

Requirements

NOTE! Knowledge of networking systems is required in order to configure Fronius system monitoring for the network.
If you are integrating Fronius system monitoring into an existing network, you must adapt the address settings in line with the network.

e.g.: Network address space = 192.168.1.x, subnet mask = 255.255.255.0
– An IP address of between 192.168.1.1 and 192.168.1.254 must be assigned to Fronius system monitoring.
– The selected IP address must not be in use on the network already. – The subnet mask must match that of the existing network (e.g.
255.255.255.0).
If you want Fronius system monitoring to send service messages or to transmit data to Fronius Solar.web, you must enter a gateway address and a DNS server address. Fronius system monitoring uses the gateway address for the purpose of establishing an Internet connection. An example of a suitable gateway address would be the IP address of the DSL router.
IMPORTANT! – Fronius system monitoring must never be assigned the same IP address as
the PC/laptop itself! – Fronius system monitoring is not capable of connecting to the Internet on its
own. In the case of a DSL connection, a router has to establish the Internet connection.

General firewall settings

DSL routers usually allow data to be sent over the internet and so do not normally have to be configured for this purpose.
Server addresses for data transfer If a firewall is used for outgoing connections, the following protocols, server addresses and ports must be allowed for successful data transfer: – Tcp fronius-se-iot.azure- devices.net:8883 – Tcp fronius-se-iot.azure-devices.net:443 – Tcp fronius-se- iot-telemetry.azure-devices.net:8883 – Tcp fronius-se-iot-telemetry.azure- devices.net:443 – Udp sera-gen24.fronius.com:1194 (213.33.117.120:1194) – Tcp froniusseiot.blob.core.windows.net:443 – Tcp provisioning.solarweb.com:443 – Tcp cure-se.fronius.com:443 – NTP 0.time.fronius.com – Tcp http://firmware- download.fronius.com:80 – Upd/Tcp 0.time.fronius.com:123
If existing firewall rules block the connection to the Fronius system monitoring function, the following firewall rules must be added:

Sending of service messages
Ability to connect to Datamanager via Fronius Solar.web
Ability to connect to Datamanager via Fronius Solar.access or Fronius Solar.service
Ability to access the Datamanager web page

49049/UDP output x x
–

80/TCP *) Input –
x x

Configure the firewall so that data can be sent from the Fronius system monitoring IP address to port 49049/UDP of “fdmp.solarweb.com”.
*) We recommend only allowing access to the web interface of the Fronius system monitoring function from secure networks. If internet access is absolutely necessary (e.g. for service purposes within a defined time period), configure the network router in such a way that requests for any external port are redirected to port 80/TCP. Caution – the inverter will therefore be visible on the internet and at will be at an increased risk of network attacks.

Using Fronius Solar.web and sending service messages

An Internet connection is required if you want to use Fronius Solar.web or to send service messages.
Fronius system monitoring is not capable of connecting to the Internet on its own. In the case of a DSL connection, a router has to establish the Internet connection.

IMPORTANT! Danger of deep discharge of an unactivated battery This may result in permanent damage to the battery.
The Solar Web wizard needs to be run in order to activate the battery and, if necessary, the Smart Meter.
5 Run the Solar Web wizard and follow the instructions
The Fronius Solar.start homepage or the Fronius system monitoring web page is displayed.

Information to help you work through the technician wizard

The technician wizard consists of 5 steps:
1. General General system data (e.g. system name) is entered here
2. Service password Enter (and make a note of) the service password.
3. IO assignment Settings for the IO interface are entered (see also General for IO assignment on page 96)
4. System overview Settings for the entire PV system are entered (see also System overview on page 111)
5. Dynamic power Settings for dynamic power reduction are entered (see also DNO Editor Dynamic power reduction on page 116)
Once you have worked your way through the technician wizard, an automatic process is triggered to calibrate all the components. This involves charging the Fronius Solar Battery fully. After that, the system automatically starts in the set operating mode. This calibration charging process is also performed automatically during actual operation after a number of charging and discharging cycles. When this calibration charge is performed depends on a number of different factors, such as the average state of charge or the energy throughput through the battery. The time can therefore vary depending on the time of year as well.
If the “permit battery charging from DNO grid” setting is deactivated, this calibration charging process relies exclusively on energy from the photovoltaic system when operating under normal conditions. Depending on the insolation conditions and size of the systems concerned, the charging process can take a very long time. If the “permit battery charging from DNO grid” setting is activated, the calibration charging process is performed by drawing a constant current from the photovoltaic system and the DNO grid.
IMPORTANT! The automatic process for fully charging the battery may result in energy being drawn from the DNO grid. The process can take several hours and cannot be aborted.

Testing backup power mode

NOTE!
Danger from immediate inverter operation in backup power mode without a connection to the grid having been previously established. During grid- connected operation, the inverter recognises and stores the direction of phase rotation in the household network. Without a grid connection, no information is available regarding the direction of rotation and the inverter feeds energy with a default direction of rotation. This can cause the three-phase consumers in the household network to experience errors.

Backup power mode should be tested once it has been installed and set up for the first time. A battery state of charge of over 30% is recommended when in test mode.
A description of how to perform the test operation can be found in the chapter “Backup power checklist” of the document “Fronius Energy Package – Examples of backup power switchover”.

Settings Passwords

General remarks

Access to Fronius system monitoring is controlled by assigning passwords.
There are 3 different types of password available for this purpose:
– The administrator password – The service password – The user password

Passwords

Administrator password User name = admin
The administrator password is set during the commissioning process and grants the user read access and the right to change settings. The user can open the Settings menu and enter all settings apart from those for “DNO Editor” and “Meter”.
If an administrator password has been set, the user must enter the user name and password in order to open the Settings menu.
Service password User name = service
The service password is usually assigned by the service technician or system installer when running the Setup wizard and it provides access to system- specific parameters. The service password is required to modify meter and DNO Editor settings. The “Meter” and “DNO Editor” menu items cannot be accessed unless a service password has been assigned.
User password When the ‘Protect your system monitoring from unauthorized read access’ selection box is checked, the user password is displayed, user name = user.
If a user password has been assigned, the user only has read permissions. The user is not able to open the “Settings” menu.
If a user password is assigned, the user is required to enter the user name and password whenever they want to establish a connection.

Settings Network

Internet via WLAN

The networks found are displayed.
Clicking on the refresh button will carry out a second search of the available WLAN networks.
Hidden networks can be added using the “Add WLAN” menu.
“Set” button – For saving a selected WLAN network. Clicking the button opens the “WLAN Connection” window
“Delete” button – For deleting a saved WLAN network.
“Configure WLAN IP” button – After clicking the button, the “Configure IP” window opens with the same setting options as with a LAN connection.
“Connect via WPS” button – To access a WLAN via WPS without needing the WLAN password: 1. Activate WPS on the WLAN router (see documentation provided with the WLAN router) 2. Click the ‘Connect via WPS’ button 3. The WLAN connection is established automatically

Internet via LAN

Setting options: – “Obtain address” – statically
The user needs to enter a fixed IP address for the Datamanager (system monitoring) and also defines the subnet mask, the gateway address and the DNS server address (from the provider). – “Obtain address” – dynamically The Datamanager (system monitoring) fetches the IP address from a DHCP server (DHCP = Dynamic Host Configuration Protocol). The DHCP server must be configured so that the same IP address is always assigned to the Datamanager (system monitoring). This means that you always know which IP address can be used to reach the Datamanager (system monitoring) datalogger. If the DHCP server supports the DNS dynamic updates function, a name can be assigned to the Datamanager (system monitoring) in the “Host name” field. As a result, the connection to the Datamanager (system monitoring) can be established using the name instead of the IP address. For example: Host name = sample_system, domain name = fronius.com The Datamanager (system monitoring) can be reached via the address “sample_system.fronius.com”.

Energy storage device

The pin for activating the energy storage device can be selected here. This setting only needs to be made for certain energy storage devices.
If an energy storage device pin is set, then emergency power pins cannot be configured.

Settings – load management

Load management

Energy management controlling priorities If additional components (e.g. battery, Ohmpilot) are available in the system, the priorities can be set here. Devices with a higher priority are activated first, followed by the others if surplus energy is available.
Load management Up to four different load management rules can be defined. If the thresholds are the same, the rules are activated in sequence. During deactivation, it is the other way round; the last IO switched on is the first to be switched off. If the thresholds are different, the IO with the lowest threshold is switched on first, followed by the one with the second lowest threshold and so on.
IOs which are controlled through the power produced are always at an advantage over the battery and Ohmpilot. This means an IO can switch itself on, resulting in the battery no longer being charged or the Ohmpilot no longer being activated
An IO is only activated or deactivated after 60 sec.
Control – Control via Energy Manager deactivated. – Control via Energy Manager is based on the power produced. – Control via Energy Manager is based on surplus power (with feed-in limits).
This option can only be selected if a meter has been connected. Control via Energy Manger is based on the amount of energy actually fed into the grid.
Thresholds – on: For entering an effective power limit as of which the output is to be activ-
ated – off: For entering an effective power limit as of which the output is to be de-
activated.
Duration – Field for activating the minimum running time per switch-on operation – Field for specifying the minimum amount of time that the output should re-
main activated for per switch-on operation. – Field for activating the maximum running time per day – Field for specifying the maximum total amount of time that the output
should be activated for per day (allowing for several switch-on operations).
Desired duration – Field for activating a desired running time

The following functions are part of inverter control: – On/Off – Power reduction – Specification of a constant cos phi power factor – Specification of a constant reactive power value
“Control priorities” The control priorities define which service takes priority during inverter control. 1 = highest priority, 3 = lowest priority The control priorities can only be changed under the “DNO EDITOR” menu item.

Restricting control

The “Restrict the control” option is only available with TCP transmission protocols. It prevents unauthorised persons from issuing inverter control commands by only allowing certain devices to perform control functions.
IP address field. If inverter control is to be limited to one or more devices, use this field to enter the IP addresses of the one(s) that is/are allowed to send commands to the Fronius Datamanager. Use commas to separate multiple entries.
Examples: – One IP address: 98.7.65.4 – Inverter may only be controlled by IP address
98.7.65.4 – Multiple IP addresses: 98.7.65.4,222.44.33.1 – Inverter may only be con-
trolled by IP addresses 98.7.65.4 and 222.44.33.1 – IP address space could (for example) be specified as a range from 98.7.65.1
to 98.7.65.254 (CIDR notation) as follows: 98.7.65.0/24 – Inverter may only be controlled by IP addresses 98.7.65.1 to 98.7.65.254

Settings Energy Manager

Energy management

Own consumption optimization The Fronius hybrid inverter always controls the system by adjusting it in line with the target value set at the metering point. In the “automatic” operating mode (factory setting), an adjustment is made to 0 W at the feed-in point (maximum self-consumption).

The target value also applies if a further source feeds into this metering point.
However, in this case:
– The Fronius Smart Meter must be installed at the feed-in point – It is necessary to activate battery charging by a further producer (see
chapter Battery management on page 106)

The self-consumption optimisation has lower priority than the battery control specifications.

Own consumption optimization Option for selecting automatic or manual self- consumption optimisation

Target value at the metering point If you opt for “manual” under “Own consumption optimization”, you can select the target value at the metering point and choose between “Consumption” and “Feed-in” here

Backup power
Operating mode “Automatic” or “Off” can be selected for backup power mode. The backup power functionality can only be activated once the required IO assignments have been configured for backup power. The meter must be installed at the feed-in point and configured.
Residual battery capacity Energy is drawn from the battery in grid-connected operation until this residual battery capacity is reached. In backup power mode without a grid, the battery is always discharged to the minimum SOC preset by the battery manufacturer.
SOC warning level A warning is output when the residual capacity of the battery specified here is reached in backup power mode.

Battery management

Battery charging/discharging limits: The battery charging / discharging limits can be set “automatically” or “manually”. If they are set automatically, suitable values are selected for the battery. If they are set manually, values can be set in the “Max SoC” (maximum state of charge) and “Min SoC” (minimum state of charge) fields. The range of values that can be set differs depending on the battery. In backup power mode without a grid, the set values are not taken into account. IMPORTANT! The settings must be agreed with the battery manufacturer! Fronius accepts no liability for damage to third-party batteries.

Battery control specification: Using the time-dependent battery control, it is possible to prevent or restrict the charging/discharging and to specify a defined value for charging/discharging.

The battery is affected by external factors, such as calibration charging, permitting AC charging, inverter power limitation, control parameters via Modbus or self-consumption optimisation. The battery control specifications have the second lowest priority, following the self-consumption optimization, and it may be the case that these are not fulfilled due to other specifications.

Without any battery control specifications, optimization is performed to establish the best possible degree of self-consumption. Self-consumption decreases when battery control specifications are defined.

The following values can be selected in the column “regulation”:
– max charging power The battery is charged at no more than the power set in the field “power”
– min charging power The battery is charged at no less than the power set in the field “power”
– max discharging power The battery is discharged at no more than the power set in the field “power”
– min discharging power The battery is discharged at no less than the power set in the field “power”

The day and time window in which this regulation applies is defined in the columns “Day of the week” and “Time window”. It is not possible to define a time window over midnight. Example: Two entries are needed to set a parameter of 22:00 to 06:00: ’22:00 24:00′ and ’00:00 – 06:00′.

Examples for the battery control specifications can be found in the following chapter.

Calibration charging (only for Fronius Solar Battery) At regular intervals, the Fronius hybrid inverter automatically charges the Fronius Solar Battery until it is full for the purpose of calibrating all the components. This process can be started manually here.

IMPORTANT! When calibration charging is activated, normal operation is interrupted and the system may draw energy from the distribution network operator’s grid. The process can take several hours and cannot be aborted.

Once calibration is complete, the system automatically reverts to the operating mode that was set originally. This calibration charging process is also performed automatically during actual operation after a number of charging and discharging cycles.

If the “permit battery charging from DNO grid” setting is deactivated, this calibration charging process relies exclusively on energy from the photovoltaic sys-

106

tem. Depending on the insolation conditions and size of the systems concerned, the charging process can take a very long time. If the “permit battery charging from DNO grid” setting is activated, the calibration charging process is performed by drawing a constant current from the photovoltaic system and the distribution network operator’s grid.

Permitted battery control parameters

The following battery control parameters are possible – Maximum charging power – Minimum charging power – Maximum discharging power – Minimum discharging power
A parameter always consists of one of the four limitations above and the times during which the limitation applies. At any one time, none, one or a maximum of two limitations that are compatible with one another can be active.

Maximum charging and discharging limits The max. charging and max. discharging power can be configured at the same time.

PV power reduction

The battery control parameters make the generated energy as optimally usable as possible. However, situations may arise in which PV energy cannot be fully used due to battery control parameters.

Example Fronius Symo Hybrid 3.0-S: Fronius Solar Battery 7.5

3000 W (max. output power)

Defined discharge PV power

3000 W 1000 W

In this case, the inverter would need to reduce the PV power to 0 W, as the output power of the Fronius Symo Hybrid 3.0-S is max. 3,000 W and the device is already fully utilised through the discharging.
Since it does not make sense to waste PV power, the power limitation for the battery control parameters is automatically adjusted so that no PV power is wasted. In the above example, this means that the battery is only discharged with 2,000 W, so that the 1,000 W of PV power can be used.
