1. SAFETY WARNING !!! HIGH LIFE RISK DUE TO FIRE OR ELECTROCUTION. The Sunsynk Parity Hybrid Inverter can only be installed by a qualified licensed electrical contractor. This is not a DIY product. Be sure to read this manual thoroughly before installation.
15. Ground connection 16. Data logger The Sunsynk Hybrid Parity Inverter is a highly efficient power management tool that allows the user to hit those ‘parity’ targets by managing power flow from multiple sources such as solar, main electrical grids, and generator, and then effectively storing and releasing electric power as the utilities require.

3. INSTALLATION 3.1. Selecting the mounting area DO NOT install the inverter in the following areas: Areas with high salt content, such as the marine environment. It will deteriorate metal parts, causing the parts to fail or the unit to leak water.
Even if they are installed more than 1m apart, it is still possible to receive noise under some signal conditions. If children under 10 years old may approach the unit, take preventive measures so that they cannot reach and touch the unit.
Risk of injury when lifting and from falling inverter Remember that this inverter is heavy (See section 2 “Technical Data”)! Please be careful when removing the inverter from the packaging and mounting it onto the wall. 3.3. Battery Connection ...
Before making the final DC connection or closing the DC breaker/disconnection device, ensure that the inverter is wired properly. Reverse polarity connection on the battery will damage the inverter. Recommended DC Surge Protector: 3.3.1 Connecting a Lithium Battery When connecting a Lithium battery, follow the connection steps bellow and then check section 4.13 “Setting Up a Lithium Battery”...
3.4. AC Connection – Single Inverter or Multi Inverter System All wiring and cable sizing must be following the country wiring regulations and code of practices. Ensure that suitable disconnection devices and RCDs are fitted. NOTES Depending on the battery type, the inverter should be capable of controlling the batteries BMS.

GEN/AUX Connection for a generator This works like a conventional grid-tied inverter. It is both an in and out GRID connection for non-essential load and supply Connection of essential loads such as lighting, security systems, and LOAD internet Recommended AC Surge Protector Please ensure you use suitable protection devices.
3.5. 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 17
IMPORTANT !!! See below for information to determine if the CT coil is connected the correct way around: 1. First of all, ensure that the CT is measuring some power flowing into the house/inverter by switching off the "Time Of Use" setting and disconnecting the PV panels.
3.5. Connecting the PV The inverter has two built-in MPPT controllers, MPPT 1 and MPPT 2, which can connect two arrays of photovoltaic panels in parallel with a maximum current of 18 Amp (as shown below). Before connecting to PV modules, install a separate DC circuit breaker between the inverter and PV modules.

4.2. Switching ON/OFF Once the inverter has been properly installed and the batteries are connected, press the on/off button (located on the left side of the case) to turn-on the system. When the system is connected without a battery but connected with either PV or grid and the on/off button is switched off, the LCD will still light up (display will show off).

Use battery SOC for all settings (%). No battery: tick this box if no battery is connected to the system. BMS setting. Active battery - This feature will help recover a battery that is 100% discharged by slowly changing from the solar array.
Shutdown causes the inverter to enter standby mode. It will not completely shut down the inverter. The total shutdown is below 19V. The voltage displayed on the Sunsynk Parity Inverter will vary depending on whether the inverter is charging or discharging the batteries.
State of Charge Bulk: Involves about 80% of the recharge in which the charger current is held constant (in a constant current charger), and voltage increases. The properly sized charger will give the battery as much current as it will accept up to charger capacity (25% of battery capacity in Amp hours) Absorption: Remaining charge equals 20%, approximately.

NOTE Some types of lithium battery the BMS cannot be controlled by Sunsynk inverter. In this case, treat the battery as a lead-acid type and set the charging and discharging protocol following the battery manufacturer specification.
IMPORTANT When not using communications between battery and inverter, never overcharge your battery bank concerning current and 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.

Concerning the detailed figure above: 1. Tick this box to do 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).
Example: This is a zero export power to the grid example. Power is supplying the non-essential load and maximum power of the inverter is set as 8kW. The inverter is connected to the grid, but no export is performed. It allows small amounts of power to flow from the grid (set as 100W in this case) to prevent any backflow.
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 8.8kW inverters that can be paralleled in a single phase utility grid is three (26.4kW) and the maximum number that can be paralleled...
Page 34
IMPORTANT Be careful with bus bar sizes. The CT coils used to limit export power must only be connected to the master. Therefore, if six inverters are paralleled, three CT coils will be required. Connect a RJ45 communication cable between each inverter; the order is not important since both sockets are the same, so there is no IN or OUT.

Most wind turbines are three-phase PM type. Therefore, either a wind turbine controller or a direct connection to the MPPT via a simple protection circuit will be required. Dump Load: When the battery (battery bank) is fully charged and the water turbine/wind turbine/solar module is still generating power, a dump load will provide the electricity a path to flow.
