    2. PRODUCT INTRODUCTION The Sunsynk Three-Phase Hybrid Inverter is a highly efficient power management tool that al- lows 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 17: Mounting The Inverter

    ALSO CONSIDER: ƒ 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.
  • Page 18 Choose the recommend drill head (as shown in below pic) 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 holding it, make sure the hanger aim at the expansion bolt,fix the inverter on the wall.

  • Page 19: Battery Connection

    4.4. Battery Connection For safe operation and compliance, an individual DC overcurrent protector or disconnection device is required for the connection of the battery and the inverter. Users are recommended to utilise a suitable fuse and DC isolator (see next page). In some applications, switching devices may not be required, but overcurrent protectors must be used.

    Without a remote temperature sensor, lead-acid batteries may undercharge or overcharge de- pending on the ambient temperature of the installation environment. This may result in a fire hazard. Depending on the battery type, the inverter should be capable of controlling the batteries BMS.
  • Page 23 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 Be- fore making GRID, LOAD, and GEN port connections, make sure to turn off the AC breaker or disconnector first.

    Since the inverter is a true hybrid then the bond must only be made when the inverter is oper- ating in Islanding Mode. To accommodate this, Sunsynk provides an AC output, which is con- nected to the A/T/S connections 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 28: Pv Connection

    The grid power may still be present, but the inverter is not draining power from it since the unit is working in ‘Island Mode’. You can verify if there is a voltage when the inverter is disconnected from the grid by using a simple multimeter.

    When communications between battery and inverter does not exist, do not over- charge your battery bank (current or voltage). Many lithium batteries are limited to 100A, some are lower and some are higher. Ensure that voltage and current speci- fications provided by the battery manufacturer are followed. If you are using lead acid batteries then follow the equation of C x 0.25 which means that the maximum charge or discharge you can apply to a battery is a quarter of the AH rating of the overall battery array.
