Page 16: Battery Connection
4.4. 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 17 CAUTION All wiring/connecting must be performed by qualified personnel. Before making the final DC con- nection or closing the DC Breaker/disconnection device, ensure the inverter unit is wired correctly. A reverse-polarity connection on the battery will damage the inverter. Please follow below steps to implement battery connection: 1.

PLEASE NOTE Depending on the battery type, the inverter should be capable of controlling the batteries 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.

4.7. Connecting the AC Before connecting to grid, please install a separate AC breaker between inverter and grid. Also, it is recom- mended that installs an AC breaker between backup load and inverter. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current. For the 3/3.6/5/6KW mod- el, the recommended AC breaker for backup load is 32A/40A. -

4.9. Installing the CT Coil The CT coil is one of the most important parts of the Sunsynk Parity 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 26 If the CT coil is fitted in the wrong way then this variable will have neg- ative instead of positive values when the power is flowing into the house/ inverter. Also, the inverter export limiting function will not work prop- erly.

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 44: 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 45 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 50: 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 51 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 52 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 53 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 54: 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 55 What this page displays: Normal connect: The allowed grid voltage/frequency range when the inverter first time connects to the ƒ grid. Normal Ramp rate: It is the startup power ramp. ƒ Reconnect after trip: The allowed grid voltage/frequency range for the inverter connects the grid after ƒ...
- Page 56 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 57 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 58: Advanced Settings For Paralleling Inverters
Set the Modbus SN for paralleling. The Sunsynk 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 paralleled 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 59 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 60 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 65: 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 66 For Gen Input mode: Gen Input: Tick this box if using a Generator.
