4.5.1.Temperature Sensor Connection for Lead-Acid Battery
Without a remote temperature sensor, lead-acid batteries may undercharge or overcharge depending on the ambient temperature of the installation environment. This may result in a fire hazard.
PLEASE NOTE
Depending on the battery type, the inverter should be capable of controlling the battery BMS. Therefore, you need to set the protocol of the BMS on both the battery and the inverter. When using more than one battery, the first battery will be the master, and the other batteries will be the slaves. Please, check the battery manufacturer’s specifications for proper operation. To verify if the battery is communicating, access the Li-BMS menu as detailed in section 5.13, ‘Setting Up a Lithium Battery’, and check whether the values are realistic. It is important that the charge and discharge limits on that page match the numbers expected for the number of connected batteries. 21 THREE PHASE HI 8~12kW | Installer Manual

4.5.2.Connecting the AC and Backup Load Connection
Before connecting to the main grid, please install a separate AC Breaker (MCB) between the inverter and the grid. In addition, it is recommended the installation of an AC Breaker between the backup load and inverter. This will ensure the inverter can be disconnected safely during maintenance and fully protect the system from over-current. The recommended AC Breaker is 20A for 8kW, 32A for 10kW and 32A for 12kW. There are three terminal blocks marked as GRID, LOAD, and GEN. Please do not confuse input and output connections.

GEN/AUX GRID LOAD

Generator connection. This works like a conventional grid-tied inverter. It is both an input and output
connection for non-essential load and supply. Connection of essential loads such as lighting, security systems, and Internet

CAUTION
All wiring and cable sizes must comply with your particular country’s wiring regulations and Codes of Practices. Ensure that suitable disconnection devices and RCDs are fitted.
Please follow the steps below to implement GRID, LOAD, and GEN port connections: 1. Before making GRID, LOAD, and GEN port connections, make sure to turn off the AC breaker or
disconnector first. 2. Remove a 10mm sleeve from each wire, unscrew the bolts, insert the cables according to the polarities
indicated on the terminal block and tighten the terminal screws. Ensure the connection is complete.

3. Then, insert AC output wires according to the polarities indicated on the terminal block and tighten the terminal. Make sure to connect corresponding N wires and PE wires to related terminals as well.
4. Ensure the wires are securely connected.
22 THREE PHASE HI 8~12kW | Installer Manual

5. Check that the AC power source is isolated before attempting to connect it to the inverter. Insert AC output wires according to the polarities indicated on the terminal block and tighten the terminal screws. Be sure to connect the corresponding N wires and PE wires to the correct terminals and ensure the wires are securely connected.
CAUTION
Ensure the AC power source is disconnected before attempting to wire it to the unit.
PLEASE NOTE
Appliances such as air conditioners require 2-3 minutes to restart as they need enough time to balance refrigerant gas inside the circuit. Suppose a power shortage occurs and recovery is made in a short time. In that case, it will cause damage to your connected appliances. In order to prevent this kind of damage, please check with the manufacturer of the air conditioner to confirm if the unit is equipped with a time-delay function before installation. If it does not have that function, the inverter will trigger an `overload’ fault and cut off the output to protect your appliance. This may cause damage to the air conditioner. Please ensure you use suitable protection devices. Switchgear and fuses must follow the local wiring standards. A figure of the complete system is presented below.

4.6.Connecting the CT Coil
The CT coil is one of the most important parts of the Sunsynk inverter. This device reduces the power of the inverter to prevent feeding power to the grid. This feature is also known as “Zero Export”. 1. Fit the coil (sensor) around the live cable on the main fuse feeding the building and run the cable back to
the inverter. If using an external meter, you can extend the cable for more than 10 metres. Plese consult the meter manual on distance. 2. Connect the other end of the CT coil to the inverter terminals.
PLEASE NOTE
When the inverter is in the off-grid state, the N line needs to be connected to the earth. 24 THREE PHASE HI 8~12kW | Installer Manual

25 THREE PHASE HI 8~12kW | Installer Manual

All neutrals can be linked together to maintain the neutral bond. When a Neural Earth bond is required for an Off-grid’ operation, then it has to be removed onGrid-Tied’ operation.
If an Earth Bond is required between neutral and earth and your system is a hybrid system, then you can have a permanent earth wire since this can cause faults with an RCD before the inverter. Since the inverter is a true hybrid, then the bond must only be made when the inverter is operating in Islanding Mode. To accommodate this, Sunsynk provides an AC output, which is connected to the A/T/S connections whenever the inverter is running on Island Mode. Therefore, you can simply connect the coil of an AC relay to the ATS 240 connections. Next, you need to select Signal Island Mode on the battery charge menu (click on the gear icon -> battery icon), as shown in the figure below.
PLEASE NOTE
The grid power may still be present, but the inverter is not draining power from it since the unit is working in `Island Mode’.
You can verify if there is a voltage when the inverter is disconnected from the grid by using a simple multimeter.
26 THREE PHASE HI 8~12kW | Installer Manual

4.9.PV Connection
Before connecting to PV panels, install a separate DC circuit breaker between the inverter and PV modules. In addition, we request users install PV junction boxes with surge protection to protect the system from a lightning strike. To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter. For example, grounded PV modules will cause current leakage to the inverter. In order to reduce risk of injury, please use the recommended cable sizes as shown below:

The correct steps in assembling the DC connector are explained below: 1. Strip 7mm of the plastic coating off the DC wire and disassemble the connector cap nut.

2. Crimp metal terminals with crimping pliers.
3. Insert the contact pin into the connector housing until it locks into place. Then screw the cap nut onto the connector housing. Torque to 2.5-3 N.m.
28 THREE PHASE HI 8~12kW | Installer Manual

4. Finally, insert the DC connector into the positive and negative input of the inverter.
PLEASE NOTE
When sunlight falls on the solar panel, it will generate a voltage. A high voltage generated by panels in a series configuration may cause danger to life. Therefore, before connecting the DC-Input line, the solar panel’s surface should be shielded from the sun’s rays by some opaque material, and the DC switch should be off. This will prevent a high voltage from flowing to the inverter, thereby causing risk to persons conducting installation or maintenance.

Using a generator with a Sunsynk inverter:
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 autostart generators on a boat. (Sunsynk will be releasing a new OS E406 ( Auto-Start ) for better generator control).

PLEASE 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.

45 THREE PHASE HI 8~12kW | Installer Manual

The batteries recommended for use with the Sunsynk systems are AGM Lead Acid or Lithium Battery Banks. (AGM’ means Absorbed Glass Matt construction that allows the electrolyte to be suspended new the plate’s active material. In theory, this enhances both the discharge and recharging efficiency. AGM batteries are very heavy as a result). 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 theequalisation 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. 5.13.Setting Up a Lithium Battery To set up a lithium-ion battery, click on the BATTERY icon and visit theBatt Type’ column.
What this page displays:
This information will only display if the Lithium’ option is selected under Batt Type’. The type of communion protocol. Approved batteries. 46 THREE PHASE HI 8~12kW | Installer 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.

PLEASE 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.

PLEASE 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.

52 THREE PHASE HI 8~12kW | Installer Manual

5.14.Program Charge & Discharge Times
To set Charge’ andDischarge’ times, click on the System Mode’ icon after clicking on the gear icon. What this page displays: A setting to prevent the inverter exporting power to the grid –Zero Export’. The ability to limit power supply to only the household loads – Solar Export’. Set the power limits to supply only the loads connected to the LOAD port –Priority to Load Only’. What you can do from this page: Set a real time to start and stop charging or discharging the battery. Choose to charge the battery from the grid or generator. Limit export power to the grid. Set the unit to charge the battery from the grid or generator ticking Grid’ orGen’ and set what times this
needs to occur. Set the time to discharge the unit to the load or export to the grid by unticking Grid’ andGen’.
Concerning the detailed next figures: 1. Tick this box to not export power back to the grid (the CT coil will detect power flowing back to the grid
and will reduce the power of the inverter only to supply the local load). 2. Tick this box if you wish to export your solar power back to the grid. 3. Tick this box if you only want to supply power to the load side of the inverter. 4. Zero Export Power’ is the amount of power flowing from the grid to the inverter. Set this value to ’20 – 100W’ to instruct the inverter to always take the prescribed amount of power from the grid to minimise the tripping of sensitive pre-paid electricity meters ifReverse Power Detection’ occurs. 5. This controls the maximum overall power, both to the Load’ andGrid’ ports combined. It is set to Low if an over-current’ fault occurs. 6. Tick this box if you wish to set the solar panels to give power to theLoad’. If you untick this box, the solar will send power to charge the batteries.
53 THREE PHASE HI 8~12kW | Installer Manual

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. 54 THREE PHASE HI 8~12kW | Installer Manual

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. 5.15.Grid Supply Page On the Settings Menu, click on the GRID icon. What this page displays: Grid frequency setting. Grid type (normally 230V three-phase). What you can do from this page: Change the grid’s frequency setting (normally 50 Hz) Set the Maximum Grid Input Voltage (Grid Vol High’) Set the Minimum Grid Input Voltage (Grid Vol Low’) Set the Maximum Grid Frequency (Grid Hz High’) Set the Minimum Grid Frequency (`Grid Hz Low) 55 THREE PHASE HI 8~12kW | Installer Manual

Select the correct Grid Type in your local area; otherwise, the machine will not work or be damaged. Select the correct Grid Frequency in your local area.
5.16.Advanced Settings for Paralleling Inverters
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. 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. The Sunsynk inverter can be wired standalone, or it can be connected in parallel when more power is required. The maximum number of inverters that can be paralleled in a three-phase utility grid is 10. In the case where 10 inverters are operating in parallel, one will operate as the Master and the other ones as Slaves. For stability, all the batteries need to be connected in parallel. A minimum cable size of 50mm is recommended, with fuse isolators for each inverter. Each invert will require a fuse isolator with surge protection, and each group circuit will require an RCD. If the batteries are 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
sockets are the same, so there is no IN or OUT. 56 THREE PHASE HI 8~12kW | Installer Manual

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, it is important to first check firmware
versions to be the same on all inverters. It is strongly recommended to request firmware updates on all inverters to the latest and the exact same firmware version. IMPORTANT: All inverters in a parallel system must have their 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 that all inverters are programmed correctly in parallel, the isolating breakers can be switched on, which then feed to the main load output breaker that feeds the loads.
PLEASE 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.
57 THREE PHASE HI 8~12kW | Installer Manual

PLEASE NOTE
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
generator’s frequency and the grid’s frequency.
Some 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.
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.

5.19.Advanced Settings for Wind Turbines
To configure wind turbine settings, click on the ADVANCE icon.

What this page displays: If one or both of the MPPTs are connected to a wind turbine. What you can do from this page: Select the MPPT to be used as a turbine input. The table below shows the maximum current depending on the voltage of the wind turbine.

PLEASE NOTE
DO NOT use a wind turbine that exceeds 400V.
Use a self-breaking wind turbine. Once the batteries are fully charged and the inverter is not exporting any power, the load can drop. This can cause the turbine to speed up dramatically, which can be very dangerous and usually happens suddenly. Thus, it is essential to use a self-breaking turbine.

60 THREE PHASE HI 8~12kW | Installer Manual

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.
5.20.Advanced Settings for Auxiliary Load
To configure Auxiliary Load (previously known as “smart load”) settings, click on the AUX LOAD icon. What this page displays: Use of the Gen (Aux) input or output. What you can do from this page: Set up a generator input. Set up an auxiliary (smart) load. Set up Peak Power Shaving. Use an additional inverter or micro inverter. A nice feature of this page is that when the batteries are full and the inverter is still producing power from the solar PV or turbine, it is possible to direct the power generated to another load such as a water heater.

6.COMMISSIONING 6.1.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)
6.2.Information for Commissioning the Inverter
After you have successfully powered up the inverter, it must be programmed and set up as per the programming feature above.
68 THREE PHASE HI 8~12kW | Installer Manual

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 resistor, caps and rectifier

Familiarize yourself with common fault codes

6.3.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.
7.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.
