  • Page 8: Product Introduction

    2. PRODUCT INTRODUCTION The Sunsynk Three-Phase Hybrid Inverter is a highly efficient power management tool that allows the user to hit those ‘parity’ targets by managing power-flow from multiple sources such as solar, mains power (grid) and generators, and then effectively storing and releasing power as and when utilities require.

  • Page 20: Battery Connection

    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 21: Temperature Sensor Connection For Lead-Acid Battery

    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.

  • Page 22: Connecting The Ac And Backup Load Connection

    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.
  • Page 23 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.

  • Page 24: Connecting The Ct Coil

    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”.

    4.8. Meter Connection 4.8.1. System Connection for the CHNT Meter CHNT meter 4.7. Earth Connection (MANDATORY) An Earth Cable shall be connected to the earth plate on the grid size in order to prevent electric shock if the original protective conductor fails. THREE PHASE HI 8~12kW | Installer Manual...
  • Page 26 Since the inverter is a true hybrid, then the bond must only be made when the inverter is operating in Island- ing Mode. To accommodate this, Sunsynk provides an AC output, which is connected to the A/T/S connec- tions whenever the inverter is running on Island Mode. Therefore, you can simply connect the coil of an AC relay to the ATS 240 connections.

  • Page 27: Pv Connection

    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.
  • Page 28 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.

  • Page 29: Wiring System For The Inverter

    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.

The voltage displayed on the Sunsynk Parity Inverter will vary depending on whether the inverter is charging or discharging the batteries.

  • Page 46: Setting Up A Lithium Battery

    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).
  • Page 47 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.

  • Page 54 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 55: 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 56: 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 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.
  • Page 57 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...

    Most wind turbines are three-phase PM type. Therefore, either a wind turbine controller or a direct connec- tion 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.
