Page 15: Battery Connection
Inverter Hanging Plate Installation Battery Connection For safe operation and compliance, a separate DC over-current protector or disconnect device is required between the battery and the inverter. In some applications, switching devices may not be required but over-current protectors are still required. Refer to the typical amperage in the table below for the required fuse or circuit breaker size. - Page 16 WARNING All wiring/connecting must be performed by qualified personnel. Ensure the inverter unit is wired correctly before making the final DC connection or closing the DC Breaker/disconnection device. A reverse-polarity connection on the battery will damage the inverter. Please follow below steps to implement battery connection: 1.

Page 42: Setting Up A Lithium Battery
The batteries recommended for use with the Sunsynk systems are AGM Lead Acid or Lithium Battery Banks. At its core, an AGM is still a lead-acid battery. AGM stands for Absorbent Glass Mat, which refers to the tech- nology these devices use to create power. This fiberglass mat sits between the positive and negative lead plates of your battery. - Page 43 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 56: Paralleling Inverters Advanced Settings
Select the corresponding meter type according to the meter installed in the system. 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 57 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 58 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.
