If PV power and battery power are insufficient, it will take grid energy as a supplement. The hybrid inverter will not sell power to the grid. In this mode, a CT is needed. For the installation method of the CT, please refer to the chapter "CT Connection".
- Page 47 Concerning the detailed next figures: 1. Tick this box to 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 48 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%.

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 50 What this page displays: Normal connect: The allowed grid voltage/frequency range when the inverter first time connects to the ƒ grid.

Page 53: 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 15A. - Page 54 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 55 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.

Page 59: Advanced Settings For Auxiliary Load
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 60 For Gen Input mode: Gen Input: Tick this box if using a Generator. Allowed Max. power from diesel generator. ƒ Peak shaving power: This is a technique used to reduce electrical power consumption during periods ƒ of maximum demand on the utility grid. This enables the user to save substantial amounts of money due to the expensive peak power charges.
- Page 61 For Aux Load Output mode: Aux Load Output: This mode utilizes the Gen input connection as an output which only receives power when the battery SOC and PV power is above a user programmable threshold. For Example: Power=500W, ON: 100%, OFF=95%. When the PV power exceeds 500W, and battery bank SOC reaches 100%, Smart Load Port will switch on automatically and power the load connected.
