    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 pro- tectors must be used.
  • Page 19 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. There- fore, 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.

  • Page 20: Grid Connection And Backup Load Connection

    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.

  • Page 21: Pv Connection

    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.

  • Page 24: Connecting The Ct Coil

    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”.

    PLEASE NOTE When the inverter is in the off-grid state, the N line needs to be connected to the earth. In the final installation, a breaker certified according to IEC 60947-1 and IEC 60947-2 shall be installed with the equipment. 4.10. Earth Connection (MANDATORY) Ground cable shall be connected to ground plate on grid side this prevents electric shock if the original pro- tective conductor fails.

  • Page 46 50000 50000 50000 50000 50000 50000 50000W 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%.

  • Page 47: Grid Supply Page

    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.

  • Page 48: Advanced Settings For Paralleling Inverters

    Set the Modbus SN for paralleling. ƒ The Sunsynk inverter can be wired standalone, or it can be connected in parallel when more power is re- quired. 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).
  • Page 49 Each phase must only have one Master and the others set to slave. ƒ Each inverter must have a unique Modbus number. ƒ The maximum length of the communication cables is 2 meters (do not exceed this value) ƒ All batteries must be connected in parallel, and the MPPTs must be kept separate. ƒ...
