Page 17: Battery Connection
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 20: Ac And Backup Load Connection
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 21: Pv Connection
1. Switch the Grid Supply Main Switch (AC) OFF. 2. Switch the DC isolator OFF. 3. Assemble PV input connector to the inverter. 4. Use the MC4 connectors supplied by Sunsynk with the inverter. DC+ male connector (MC4) DC+ female connector (MC4) - Page 22 WARNING Before connection, please ensure the polarity of the output voltage of the PV array matches the DC+ and DC- symbols. 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 maxi- mum limit of the inverter.

Page 23: Connecting The Ct Coil
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”. -
Page 24: Meter Connection
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 25 NOTE: 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.

Example: During 01:00-05:00, when the battery SOC is lower than 80%, it will use the grid to charge the battery until the battery SOC reaches 80%. During 05:00-08:00 and 08:00-10:00, when battery SOC is higher than 40%, the hybrid inverter will discharge the battery until the SOC reaches 40%. - Page 54 IT system: For the IT grid system, the Line voltage (between any two lines in a three-phase circuit) is ƒ 230Vac.

Page 57: Paralleling Inverters Advanced Settings
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 58 Each inverter 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.
- Page 59 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. - Page 64 For Gen Input mode: Gen Input: Tick this box if using a Generator.
