Selecting the Mounting Area
This Sunsynk Ecco Hybrid Inverter is designed for outdoor use (IP65). DO NOT
install the inverter in the following areas: Areas with high salt content,
such as the marine environment. It will deteriorate the metal parts and pos-
sibly lead to water/dampness penetrating the unit. Areas filled with mineral
oil or containing splashed oil or steam such as found in kitchens. It will
deterio-
rate plastic parts of the unit, causing those parts to fail or allow
water/damp to penetrate the unit. Areas that generate substances that
adversely affect the equipment, such as sulphuric gas, chlorine gas,
acid, or alkali. These can cause the copper pipes and brazed joints to corrode
and fail to conduct electricity reliably. Areas that can cause combustible gas
to leak, which contains suspended carbon-fibre or flammable dust, or volatile
inflammable such as paint thinner or gasoline. Areas where there may be gas
leaks and where gas may settle around the unit as this is a fire risk. Areas
where animals may urinate on the unit or ammonia may be generated. High
altitude areas (over 2000 metres above sea level). Environments where
precipitation or humidity are above 95%. Areas where the air circulation is
too low. Areas exposed to direct sunlight.
Before connecting all wires, please take off the metal cover by removing

A generator can either be connected to the Grid side or to the Gen connection.
When connected to the Grid Input, the inverter will consider the power coming
from the generator as Grid Supply’. Users should ensure this power goes to the LOAD only and should not be exported to other outlets, as this will damage the generator. An advantage of connecting the generator to the Grid Input is that it can be paralleled, whereas the GEN/ AUX input cannot be paralleled. That means the inverter will extract what power it requires fromGrid Supply’ to charge its
batteries.
If the generator is connected to the inverter and a generating signal exists,
the inverter will switch 100% of the load to the generator and then slowly
increase the charging currents to the batteries. Therefore, the generator must
be able to supply both the charge current and the total load current.
The generator can be controlled via a relay with a set of dry-contacts to
enable remote control. The current on the contacts is limited to approximately
1Amp 12V.
Below is a simple reference circuit of an auto-start system that can auto-
start generators on a boat. (Sunsynk will be releasing a new OS E406 ( Auto-
Start ) for better generator control).

What this page displays: Shutdown 20%: It indicates the inverter will shutdown
if the SOC is below this value. Low Batt 20%: It indicates the inverter will
alarm if the SOC below this value. Restart 40%: Battery voltage at 40% AC
output will resume. Low Power Mode<Low Batt: If selected and when battery SOC
is less than the “Low Bat” value, the
self-consumption power of the inverter will be from the grid and battery
simultaneously. If unselected, the self-consumption power of the inverter will
be mainly from the grid. Low Noise Mode: Low noise mode is used to change the
switching frequency of the IGBTs from 15kHz to 20kHz, we did this because
15kHz was in the audible range still meaning that people with great hearing
could hear a high pitch noise when using other electrical products, the
inverter interacted with it on the AC line with electrical noise. Disable
Float Charge: A battery has three stages of charging, bulk, absorption, and
float. Once the third stage has been reached which will be the float charge
the inverter gradually charges the battery. Sometimes, this results in the
batteries being overcharged so enabling this function it will disable the
third stage in the charging cycle which is float charge. What you can do from
this page: Adjust battery shut down (voltage or %) Adjust low battery warning
(voltage or %) Adjust restart (voltage or %)
NOTE:
Activating Shutdown causes the inverter to enter standby-mode. It does not
entirely shut down the inverter. Total shutdown occurs at voltages below 19V.
The voltage displayed on the Sunsynk Parity Inverter will vary depending on
whether the inverter is charging or discharging the batteries.
Since the batteries are 48V, the figure on the left is x4: Fully Charged
50.54V (Discharge Mode) Fully Charged 58.50V (Charge Mode) 75% Charged 49.60V
(Discharge Mode) 75% Charged 54.80V (Charge Mode) 25% Charged 48.00V
(Discharge Mode) 25% Charged 50.80V (Charge Mode) Completely Discharged 47.50V
Setting the cut-off higher is better for the batteries.

The batteries recommended for use with the Sunsynk systems are AGM Lead Acid
or Lithium Battery Banks. At its core, an AGM is still a lead-acid battery.
AGM stands for Absorbent Glass Mat, which refers to the technology these
devices use to create power. This fiberglass mat sits between the positive and
negative lead plates of your battery. Then, as the name suggests, it absorbs
and holds the battery acid. That way, it doesn’t freely flow around the
battery.
State of Charge Bulk: The bulk charge is the first stage of a battery’s
charging process, where the charger identifies the battery and its needs and
then applies a high voltage to do the bulk of the charging. It involves about
80% of the recharge. The properly sized charger will give the battery as much
current as it will accept up to charger capacity (25% of battery capacity in
Amp hours). Absorption: To fully charge a battery, a period of charging at a
relatively high voltage is needed. This period of the charging process is
called absorption. This occurs when the charging of a battery has reached 80%
of its capacity. The remaining charge equals 20% approximately. It makes the
charger hold the voltage at the charger’s absorption voltage (between 14.1 VDC
and 14.8 VDC, depending on charger set points) and decreases the current until
the battery is fully charged. Float: The charging voltage is reduced to
between 13.0 VDC and 13.8 VDC and held constant, while the current is reduced
to less than 1% of battery capacity. This mode can be used to maintain a fully
charged battery indefinitely. Equalisation: This is essentially a controlled
overcharge that occurs at the end of the Bulk mode and the absorption phase
and is called the equalisation voltage’. However, technically, this phase has another function. Higher capacity wet (flooded) batteries sometimes benefit from this procedure, particularly the physically tall batteries. The electrolyte in a wet battery can stratify over time if not cycled occasionally. In equalisation, the voltage is brought up above the typical peak charging voltage well into the gassing stage and maintained for a fixed (but limited) period. This stirs up the chemistry in the entire battery, equalising’ the strength of the electrolyte and knocking off any loose
sulphating that may be on the battery plates.
Setting Up a Lithium Battery
To set up a lithium-ion battery, click on the BATTERY icon and visit the Batt Type’ column. What this page displays: This information will only display if theLithium’
option is selected under `Batt Type’. The type of communion protocol. Approved
batteries.
43 ECCO 7kW SG05LP1 | User Manual
What you can do from this page:
Set up you Lithium-ion battery.
After installing a lithium battery, check the communications page by clicking
on the `Li BMS’ icon to see if the BMS information is visible. Suppose some
information is not displayed correctly (it should look like the diagram
below), then there will be a communication error.
Therefore, if a communication error occurs: 1. Check that your data cable is
the correct type. 2. Check that the data cable is plugged into the correct
sockets. Usually, RS485 is employed, but some
battery manufacturers use others.
NOTE:
With some types of lithium batteries, the BMS cannot be controlled by the
Sunsynk inverter. In this case, treat the battery as a lead-acid type and set
the charging and discharging protocol following the battery manufacturer’s
specifications.
It is crucial to refer to the manuals that manufacturers produce for their batteries. That way, the chance of errors occurring during installation is significantly reduced. Below is a list of batteries that have been examined, tested, and approved by Sunsynk.

NOTE:
When communications between the battery and inverter do not exist, do not
overcharge your battery bank (current or voltage). Many lithium batteries are
limited to 100A, some are lower, and some are higher. Ensure that voltage and
current specifications provided by the battery manufacturer are followed.
If you are using lead acid batteries, then follow the equation of C x 0.25,
which means that the maximum charge or discharge you can apply to a battery is
a quarter of the AH rating of the overall battery array. E.g.: A 200Ah battery
array composed of 4 x 200Ah batteries in series has a maximum discharge of
only 50Ah (200 x 0.25 = 50)
Also, ensure the cable is thick enough to support the current and that the
connected fuses are of the correct rating per the battery manufacturers’
recommendations.

Example: This example shows the battery being charged up to 100% by both the
Grid and Solar PV from 8 a.m. to 11 a.m. and then being able to supply up to
4kW of battery-power to the essential’ loads from theLoad’ Port until the
battery SOC drops to 50%.
IMPORTANT – When charging the batteries from the Grid or Generator, please
ensure you have set the correct battery-charging settings on the battery
charge as shown in Section 4.10 Battery Setup’ Home Page. If theUse Timer’
function is activated then the inverter will use the battery power according
to your settings when the Grid is present. If this function is not set, the
batteries WILL ONLY be used for backup when there is no utility grid power.
Example: The power produced is supplying the `Non-Essential Load’ while the
inverter is set at a maximum power of 8kW (Max Sell Power). The inverter is
connected to the grid, but no export is performed. The unit allows small
amounts of power to flow from the Grid (100W Zero Export Power) to prevent any
back-flow. In this example, the solar PV is prioritised to supply the Load
first and then subsequently, charge the battery.

Paralleling Inverters Advanced Settings
To configure multi-inverter settings, click on the ADVANCE icon.
What this page displays: If the inverter operates as a master or a slave.
Modbus Device ID: `Modbus SN’ that must be unique for each inverter connected
to the bus/wire. Ex_Meter For CT: When in a Three-phase system with a CHNT
Three-phase energy meter (DTSU666),
click the corresponding phase where the hybrid inverter is connected. e.g.
when the hybrid inverter output connects to A phase, please click A Phase.
What you can do from this page: Set the inverter as a master or slave per
bus/wire. Set the phase in which the inverter will be paralleled. Set the
Modbus SN for paralleling. Select the meter connection. The Sunsynk Inverter
can be wired standalone or where more power is required it can be connected in
parallel either single or 3 phase configuration. The maximum number of
inverters that can be paralleled in a single phase utility grid is 16 and the
maximum number that can be paralleled in a three phase utility grid is 15A. A
master single phase inverter is capable to operate with other 15 slave
inverters. Thus, to parallel 16 inverters in a single phase utility, one will
operate as the master, and the other 15 will operate as slaves. To parallel 15
inverters in a three phase utility grid are necessary to set three inverters
as master and the others as slaves: Phase A: Master A and 4 Slaves A Phase B:
Master B and 4 Slaves B Phase C: Master C and 4 Slaves C In a three phase
utility grid, the paralleled inverters will operate as a normal three-phase
supply with perfect phase rotation, capable of power single phase (220 VLN)
and three phase (380 VLL) loads. For stability, all the batteries need to be
connected in parallel. It is recommended a minimum cable size of 50mm2
diameter with fuse isolators to each inverter.
57 ECCO 7kW SG05LP1 | User Manual
Each inverter will require a fuse isolator with surge protection and each
group circuit will require an RCD. If the batteries as supplying power to the
main load during the outage, then a change over switch will also be required
or a split load can be used. The CT coils used to limit export power must only
be connected to the master. Therefore, if six inverters
are paralleled, three CT coils will be required. Connect a RJ45 communication
cable between each inverter; the order is not important since both sock-
ets are the same, so there is no IN or OUT. Each phase must only have one
master and the others set to slave. Each inverter must have a unique Modbus
number. The maximum length of the communication cables is 2 meters (do not
exceed this value). All batteries must be connected in parallel and the MPPTs
must be kept separate.
IMPORTANT: When configuring inverters in parallel for a single or three-phase,
it is important to first check firmware versions to be all the same on all
inverters. It is strongly recommended to request firmware update on all
inverters to the latest and the exact same firmware version.
IMPORTANT: All inverters in a parallel system must have their own isolating
load breaker before it goes to the parallel breaker to ensure while
programming that the load outputs are isolated from each other.
Only once confirmed all inverters are programmed correctly in parallel or
three-phase then only the isolating breakers can be switched on, which then
feeds to the main load output breaker where the actual parallel or three-phase
connection is made that feeds the loads. When configuring a three-phase system
using three single-phase inverters, one per phase. It is extremely important
to check phase rotation to be clockwise feeding the inverters and to confirm
the output is also clockwise on phase rotation.
NOTE:
The cables have two ends, one to be specifically connected to the BMS and
another one to be connected to the inverter, do not change it. If the
communication is not working correctly between inverters, then errors will
appear on display. In this case, please check all settings and data cables.
All inverters in a parallel system must have their own isolating load breaker
before it goes to the
parallel breaker to ensure while programming that the load outputs are
isolated from each other. The grid input can also be connected in parallel.
You cannot connect the Aux/Gen port in parallel because this causes a conflict
between the gen-
erator’s frequency and the grid’s frequency.

If you need further help please refer to the Sunsynk website where you will
find training videos and Frequently Asked Questions www.sunsynk.com. Firmware
prior installation is important to be updated and all inverters in parallel or
three phase system must be the same.
Common questions that occur when paralleling inverters: Q1: What is the
sequence to install/connect/commission? First of all, leave the main supplies
off. Next, connect all communication cables, set up all LCDs and then, last of
all, turn on the main supplies. Q2: What are the indications that the
communication and the system are OK or not? Parallel errors will be shown as
fault F46 on the display. Q3: What are the consequences of not setting one
inverter in a parallel mode? It can damage the inverter. Q4: What are the
consequences of having more than one Master Inverter or having no inverter set
as `Master’? It can damage the inverter. There are cases in which it is
possible to have more than one master. For example, as aforementioned, six
inverters paralleled in a three phase utility grid (three masters). Q5: What
are the consequences for setting A, B, or C phases wrong while in parallel
mode? It can damage the inverter. Recommend checking the phase rotation with a
meter before switching on. Q6: What are the consequences of factory resetting,
power cycling, or firmware updating one inverter in a parallel system? It can
damage the inverter. Inverters needs to be isolated from each other before
factory reset or firmware update. Q7: What consequences for changing ALL/ANY
settings while operating in parallel mode? It can damage the inverter and
fault F46 will be indicated on the display.

Most wind turbines are three-phase PM type. Therefore, either a wind turbine
controller or a direct connection to the MPPT via a simple protection circuit
will be required.
Dump Load or Diversion Load is an important part of an off-grid power system.
When the battery ( Battery Bank ) is fully charged, and the water turbine /
wind turbine / solar PV module is still generating, a dump load is a useful
device to send spare electricity to. This can be done by using a switch on a
smart load option or by utilising a wind turbine controller with a built-in
dump load. Also, a hot water tank controlled via a smart-load can act as a
good `dump-load’ however, in very windy conditions it may be necessary to
shunt the output.

NOTE:
The Single-Phase Hybrid Inverter is designed for grid-connected operation. The
inverters meet the main standards concerning safety and electromagnetic
compatibility. Be-
fore leaving the factory, all inverters undergo rigorous testing to ensure the
inverter can operate reliably, as presented in Chapter 3, `Technical
Specifications’.

COMMISSIONING
Start-Up / Shutdown Procedure
The inverter must be installed by a qualified / licensed electrical engineer
in accordance with the country’s wiring regulations. Before switching on, the
installation engineer must have completed the Earth Bond, RCD and earth
leakage tests, checked that the solar panel Voc voltage does not exceed 480V
and checked the battery voltage.
Power ON Sequence: 1. Switch on AC 2. Press Start Button 3. Switch on Battery
and battery breaker 4. Switch on the DC (PV Isolator)
Shutdown Sequence: 1. Switch off AC 2. Press the start button 3. Switch off
the battery and the battery breaker 4. Switch off the DC (PV isolator)
Inverter Commissioning Info
After you have successfully powered up the inverter, it must be programmed and
set up as per the programming feature above.
Check each bond on the solar panels
Check the VOC does not exceed 480V
Ensure both MPPTs are balanced
Measure the supply voltage check it matches the settings of the inverter
If it falls out of the setting range it will cause the inverse shut down and alarm
See Grid Setup page
Check the battery charge and discharge is within
the C rating of the battery. Too high will damage the
battery
Check the battery BMS is communicating with the
inverter

This is the heart of the system this controller
everything
This is for paralleling systems, and wind turbine
Ensure you are familiar with this, if you fully under-
stand the controller you will fully appreciate the capabilities of there
inverter
If paralleling inverters in 3 Phase check you phase rotation before switching
on the AC Load, in 3 Phase
the output voltage will increase across phase to
400V
See section `Program Charge / Discharge Times’
If using a wind turbine please ensure you have the correct limiting resis-
tor, caps and rectifier
Familiarize yourself with common fault codes
GDFI Fault
Before the inverter connects to the Grid, it will detect the impedance
(effective resistance) of the solar PV + to Ground, and the impedance of the
solar PV – to ground. If any of the impedance values are less than 33k, the
inverter will not connect to the Grid and will report an error F24 on its LCD.
MAINTENANCE
The inverter is low maintenance. However, it is important that at least twice
a year (for dusty environments this may need to be carried out weekly) all the
cooling fans, air ducts are cleaned and dust free. Check if there are no fault
codes and Lithium battery communication is correct. Weekly cleaning statement:
Suggest micromesh filters as an available option, micro ants here are a real
problem.

APPENDIX C
The Sunsynk Single-Phase Hybrid Inverter inverter is compatible with the
Sunsynk Connect app, via a Wi-Fi or GSM data logger (See Sunsynk Connect
instruction manual).
APPENDIX D
If an external Residual Current Device (RCD) is used it should be of Type A/AC
with a tripping current of 30mA or higher.
Use of RCDs
Residual Current Devices (RCDs): An RCD dedicated for an Inverter Energy
System (IES) may be used to meet the mechanical cable protection requirements
of AS/NZS3000 for the cable from the switchboard to the IES. If an RCD is
installed the engineer must:
1. Disconnect all live conductors (including both active and neutral
conductors).
2. Be of the type specified in the inverter manufacturer’s instructions or as
labelled on the inverter.
We recommend the use of an RCD on all circuits and sub-circuits connected to
the Sunsynk Inverter. Below is the specifications for a Residual Current
Breaker with Overcurrent Protection (RCBO).
Earth-leakage protection class Earth-leakage sensitivity Curve code Network

Earth-leakage protection time delay
Type A 30mA
C AC 2P Instantaneous
APPENDIX E
The Sunsynk inverter can be connected to the internet, but you need to add a data logger to do this. The inverter is compatible with Sunsynk Connect data- logger, which you can obtain from us with your distributor. 1. LAN-Type Data Logger 2. Wi-Fi-Type Data Logger 3. GSM-Type Data Logger To setup the Internet connection for the Data Logger, please refer to the App User instructions. The Data Logger should be connected to the bottom of the inverter via the connection socket marked WIFI.
