    4.6. Battery Connection For safe operation and compliance, a separate DC over-current protector or disconnect device is required between the battery and the inverter. In some applications, switching devices may not be required but over-current protectors are still required. Refer to the typical amperage in the table below for the required fuse or circuit breaker size.

  • Page 19: Recommended Dc Battery Protection

    CAUTION All wiring/connecting must be performed by qualified personnel. Before making the final DC con- nection or closing the DC Breaker/disconnection device, ensure the inverter unit is wired correctly.

  • Page 22: Connecting The Ac

    4.9. Connecting the AC Before connecting to grid, please install a separate AC breaker between inverter and grid. Also, it is recom- mended that installs an AC breaker between backup load and inverter. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current. For the 3/3.6/5/6KW mod- el, the recommended AC breaker for backup load is 32A/40A.

  • Page 24: Installing The Ct Coil

    4.10. Installing the CT Coil The CT coil is one of the most important parts of the Sunsynk Ecco Hybrid Inverter. This device reduces the power of the inverter to prevent feeding power to the grid. This feature is also known as “Zero Export”.

  • Page 25: Earth Connection (Mandatory)

    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.

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 43: 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 44 PLEASE NOTE With some types of lithium battery, 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 bat- tery manufacturer specification.

  • Page 49 Concerning the detailed figures above: 1. Tick this box to do 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.

  • Page 50: 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 52: Advanced Settings For Paralleling Inverters

    Set the Modbus SN for paralleling. ƒ The Sunsynk parity 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 paral- leled in a single phase utility grid is 16 and the maximum number that can be paralleled in a three phase utility grid is 15.
  • Page 53 For stability, all the batteries need to be connected in parallel. It is recommended a minimum cable size of 50mm diameter with fuse isolators to each inverter. Each invert 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.
  • Page 54 If you need further help please refer to the Sunsynk website where you will find training videos and Fre- quently 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.

    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.
