  • Page 7: Product Introduction

    2. PRODUCT INTRODUCTION The Sunsynk Single-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.

    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. Switching devices may not be required in some applications, 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: Battery Temperature Sensor Connection

    PLEASE NOTE When connecting more than one battery, ensure they are set in the configuration of ‘master and slave’. 4.8. Battery Temperature Sensor Connection 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 batteries BMS.

  • Page 21: Connecting The Ac

    4.9. Connecting the AC 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 8KW model, the recommended AC breaker for backup load is 63A.

  • Page 23: Installing The Ct Coil

    4.10. Installing the CT Coil The CT coil is one of the most important parts of the Sunsynk Parity 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 24 If the CT coil is fitted in the wrong way then this variable will have negative instead of positive values when the power is flowing into the house/inverter. Also, the inverter export limiting function will not work properly. HYBRID INVERTER | Installer Manual...

  • 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.

    4.14. 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.

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

  • Page 49: 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 50 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 55 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 56: 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.

    Set the phase in which the inverter will be paralleled. Set the Modbus SN for paralleling. 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 paralleled in a single phase utility grid is 16 and the maximum number that can be paralleled in a three phase utility grid is 15.A...
  • Page 59 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. The CT coils used to limit export power must only be connected to the master.

    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.
