Page 18: 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 19 3. Crimp terminals: 4. Fasten terminal with a bolt: 5. Fasten the terminal with outer cover: NOTE: Depending on the battery type, the inverter should be capable of controlling the battery BMS. There- fore, you need to set the protocol of the BMS on both the battery and the inverter. When using more than one battery, the first battery will be the master, and the other batteries will be the slaves.

Page 45: Setting Up A Lithium Battery
State of Charge Bulk: The bulk charge is the first stage of a battery’s charging process, where the charger identifies the battery and its needs and then applies a high voltage to do the bulk of the charging. It involves about 80% of the recharge. - Page 46 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: 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 56 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 57 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 61: 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 62 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 63 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.
