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 possibly lead to water/dampness penetrating the unit.
• Areas filled with mineral oil or containing splashed oil or steam, such as those found in kitchens. It will deteriorate plastic parts of the unit, causing those parts to fail or allowing 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 4000 metres above sea level).
• Environments where precipitation or humidity is above 95%
• Areas where the air circulation is too low.

ALSO CONSIDER:

• Installing the indoor unit, outdoor unit, power supply cable, transmission cable, and remote control cable at least 1 metre away from any television or radio receiver. This will prevent TV reception interference or radio noise. This will prevent radio signal interference from external units that might interfere with the Wi-Fi or GSM monitoring.
• If children under 10 years old may approach the unit, take preventive measures so they cannot reach and touch the unit.
• Install the indoor unit on the wall where the floor height is higher than 1600mm.
  Before connecting all wires, please take the metal cover off, removing the screws as shown below:

4.3. Mounting the Inverter

• Install this inverter at eye level to allow the LCD to be read anytime.
• To ensure optimal operation, an appropriate ambient temperature is between -25 and 60°C.
• Be sure to keep other objects and surfaces, as shown in the figure to guarantee sufficient heat dissipation and have enough space to remove wires.\
• For proper air circulation to dissipate heat, allow a clearance of approximately 50cm to the side.

WARNING
Risk of injury (Heavy Object).
Remember that this inverter is heavy (75kg), so users must carefully handle the unit during installation, especially when mounting or removing it from a wall.
Choose the recommended drill head(as shown below) to drill 4 holes on the wall, 52-60mm deep.

1. Use a proper hammer to fit the expansion bolt into the holes.
2. Carry the inverter and hold it, ensure the hanger aims at the expansion bolt, and fix the inverter on the wall.
3. Fasten the screw head of the expansion bolt to finish the mounting.

4.4. Function Port Definition

4.5. Battery Connection
For safe operation and compliance, an individual DC overcurrent protector or disconnection device is required to connect the battery and the inverter. Users are recommended to utilise a suitable fuse and DC isolator (see next page). Switching devices may not be required in some applications, but overcurrent protectors must be used. Please refer to the typical amperage in the table below for the required fuse or circuit breaker size.

CAUTION
Reverse Polarity.
Before making the final DC connection or closing DC breaker/disconnect, be sure positive (+) must be connected to the positive (+) and negative (-) must be connected to the negative (-). A reverse polarity connection on the battery will damage the inverter.
CAUTION
All wiring/connecting must be performed by qualified personnel. In addition, connecting the battery with a suitable cable is essential for safe and efficient operation of the system Please follow below steps to implement battery connection:

Please follow below steps to implement battery connection:

1. Pass the cable through the terminal:
2. Put on the rubber ring:
3. Crimp terminals:
4. Fasten terminal with a bolt:
5. Fasten the terminal with outer cover:

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.
4.6. Grid Connection and Backup Load Connection
Before connecting to the grid, please install a separate AC breaker between the inverter and the grid. Also, it is recommended that installs an AC breaker between the backup load and inverter. This will ensure that the inverter can be securely disconnected during maintenance and fully protected from overcurrent. For the 25/30/40/50KW model, the recommended AC breaker for the backup load is 180A. For the 25/30/40/50KW model, the recommended AC breaker for the grid is 180A.
There are three terminal blocks marked as GRID, LOAD, and GEN. Please do not confuse input and output connections. External AC SPD is compulsory on all Sunsynk  inverters.
CAUTION
All wiring must be performed by qualified personnel. System safety and efficient operation need to use appropriate cable for AC input connection. To reduce the risk of injury, please use the proper recommended cables as below.
Backup Load Connection

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.
5. Appliances such as air conditioners require at least 2-3 minutes to restart because it requires enough time to balance refrigerant gas inside the circuit. If a power shortage occurs and recovers in a short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check with the air conditioner manufacturer if it is equipped with a time-delay function before installation. Otherwise, this inverter will trigger an overload fault and cut off output to protect your appliance, but sometimes it still causes internal damage to the air conditioner

4.7. 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. External AC SPD is compulsory on all Sunsynk inverters.
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:
CAUTION
To avoid malfunction, do not connect any PV modules with possible leakage current to the inverter.
For example, grounded PV modules will cause leakage current to the inverter. When using PV modules, please ensure the PV+ & PV- of the solar panel are not connected to the system ground bar.
It is requested to use a PV junction box with surge protection. Otherwise, it will cause damage to the inverter when lightning occurs on PV modules.
4.7.1. PV Module Selection
When selecting proper PV modules, please be sure to consider below parameters:

1. Open circuit Voltage (Voc) of PV modules can not exceed the max. PV array open circuit voltage of the inverter.
2. The PV modules ‘ open circuit Voltage (Voc) should be higher than min. start voltage.
3. The PV modules connected to this inverter shall be Class A rating certified according to lEC 61730.

4.7.2. PV Module Wiring

1. Switch the Grid Supply Main Switch (AC) OFF.
2. Switch the DC isolator OFF.
3. Assemble PV input connector to the inverter.

CAUTION
Before connection, please ensure the polarity of the output voltage of the PV array matches the DC+ and DC- symbols.
WARNING
Please do not connect the PV array’s positive and negative poles to the ground. This can seriously damage the inverter.
Before connecting the inverter, please make sure the PV array open-circuit voltage is within the maximum limit of the inverter.
Please utilise an approved DC cable for the PV system.

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.
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.
4.8. 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 reading of the load power on the LCD is not correct, please reverse the CT arrow.
When the inverter is in the off-grid state, the N line needs to be connected to the earth.

  5.11. Generator & Battery Page To configure battery charging settings, click on the BATTERY icon and then on ‘Batt Charge’.

What this page displays:

• Generator start voltage/SOC %.
• Grid power start voltage/SOC %.
• Float V is the voltage at which a battery is maintained after being fully charged.
• Absorption V the level of charge that can be applied without overheating the battery.
• Float V for an AGM battery is 552V.
• Absorption V is for an AGM battery is 576V.
• Equalization V for an AGM battery is 588V.
• Equalizing charge/overcharge to remove sulphate crystals that build-up on the plates over time on lead-acid batteries.

What you can do from this page:

• Tick ‘Gen Charge’ to charge the batteries from the gen I/P.
• Tick ‘Grid Charge’ to charge the batteries from the grid I/P.
• Tick ‘Gen Signal’ signal to auto-switch a relay box.
• Tick ‘Grid Signal’ signal to auto-switch a relay box.

PLEASE NOTE
Do not alter these settings too often on the same battery, as it may damage the battery.
Gen Charge: Uses the GEN input of the system to charge the battery bank from an attached generator.
Gen Signal: Normally open (NO) relay that closes when the Gen Start signal state is active.
Gen Max Run Time: This indicates the longest time the generator can run in one day. When the maximum running time is reached, the generator will be turned off. ‘24H’ means the generator will run continuously.
Gen Down Time: This indicates the delay-time of the generator to shut down after it has reached the running time
Grid Charge: It indicates that the grid will charge the battery.
Grid Signal: This indicates when the grid should no longer charge the battery.
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 from ‘Grid 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).

5.12. Battery Discharge Page
To configure inverter’s shutdown settings, click on the BATTERY icon and then on ‘Shut Down’.

What this page displays:

• Inverter shutdown voltage set as either a voltage or %.
• Inverter low battery warning set as either a voltage or %.
• Restart voltage set as either a voltage or %.

What you can do from this page:

• Adjust battery shut down (voltage or %)
• Adjust low battery warning (voltage or %)
• Adjust restart (voltage or %)

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.
5.13. 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 the ‘Lithium’ option is selected under ‘Batt Type’.
• The type of communion protocol.
• Approved batteries.

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.

5.14. Program Charge & Discharge Times
To set ‘Charge’ and ‘Discharge’ 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’ or ‘Gen’ 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’ and ‘Gen’.

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 if ‘Reverse Power Detection’ occurs.
5. This controls the maximum overall power, both to the ‘Load’ and ‘Grid’ 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 the ‘Load’. If you untick this box, the solar will send power to charge the batteries.

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 the ‘Load’ Port until the battery SOC drops to 50%.![SUNSYNK SUN 25K SG01HP3 EU BM2 Three Phase Hybrid Inverter

• fig 68](https://manuals.plus/wp-content/uploads/2023/05/SUNSYNK-SUN-25K- SG01HP3-EU-BM2-Three-Phase-Hybrid-Inverter-fig-68.jpg) 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 the ‘Use 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.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)
• 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 (this is uder development and should be ready first quarter 2023).

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 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, 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.
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 invert- er 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.

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 battery on first
2. Press on/off button and wair fot inverter to normalise
3. Switch on AC grid supply and wair for inverter to grid be *
4.  Switch on DC PV supply
5. Switch AC load breaker on only once all connections are secure and inverter is stabalised on all incoming power.
   *For a grid tied only system, switch AC on first, then the on/off button and wait for the inverter to grid tie before switching on PV.

Shutdown Sequence:

1. Load breaker to be switched off first
2. Turn PV switch off
3. Turn inverter off at on/off switch
4. Turn off batteries

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.

| Check each bond on the solar panels| Check the VOC does not exceed 480V| Ensure both MPPTs are balanced
---|---|---|---
| Measure the supply volt- age check it matches the settings of the inverter| If it falls out of the setting range it will cause the in- verse 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| Ensure you are familiar with this, if you fully under- stand the controller you will fully appreciate the ca- pabilities of there inverter|

See section ‘Program Charge / Discharge Times’

| This is for paralleling sys- tems, and wind turbine| 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|

If using a wind turbine please ensure you have the correct limiting resis- tor, 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 33kΩ, 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.
