Earth Connection (MANDATORY) An Earth Cable shall be connected to the earth plate on the grid size in order to prevent electric shock if the original protective conductor fails. - Page 28 Since the inverter is a true hybrid, then the bond must only be made when the inverter is operating in Islanding Mode. To accommodate this, Sunsynk provides an AC output, which is connected 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 45: Setting Up A Lithium Battery
Absorption: To fully charge a battery, a period of charging at a relatively high voltage is needed. This period of the charging process is called absorption. This occurs when the charging of a battery has reached 80% of its capacity. The remaining charge equals 20% approximately. It makes the charger hold the voltage at the charger’s absorption voltage (between 14.1 VDC and 14.8 VDC, depending on charger set points) and decreases the current until the battery is fully charged. - Page 46 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 51: Program Charge & Discharge Times
PLEASE NOTE When communications between the battery and inverter do not exist, do not overcharge 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 specifications provided by the battery manufacturer are followed. - Page 52 Zero Export + Limit To Load Only: The hybrid inverter will only provide power to the backup load connect- ed. The hybrid inverter will neither provide power to the home load nor sell power to the grid. The built-in CT will detect power flowing back to the grid and will reduce the power of the inverter only to supply the local load and charge the battery.
- Page 53 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 54 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 55: Grid Supply Page
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 56 What this page displays: Normal connect: The allowed grid voltage/frequency range when the inverter first time connects to the ƒ grid.

- Page 57 What this page displays: FW: This series inverter is able to adjust inverter output power according to grid frequency. ƒ Droop f: The percentage of nominal power per Hz. ƒ For example: “Start freq f>50.2Hz, Stop freq f<50.2, Droop f=40%PE/Hz” when the grid frequency reaches 50.2Hz, the inverter will decrease its active power at Droop f of 40%.
- Page 58 What this page displays: P(Q): It adjusts the inverter reactive power according to the set active power. P(PF): It adjusts the inverter PF according to the set active power. Lock-in/Pn 50%: When the inverter output active power is less than 50% rated power, it won't enter the P(PF) mode.

Page 59: Advanced Settings For Paralleling Inverters
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 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 60 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.
- Page 61 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 67 For Gen Input mode: Gen Input: Tick this box if using a Generator.
