INSTALLATION Parts List Check the equipment before installation. Please make sure nothing is damaged in the package. You should have received the items in the following package: Hybrid Inverter Wall Mounting Stainless Steel Anti-Colli- Bracket x1 sion Bolt M12x60 x4 Parallel Communication Stainless Steel Mounting L-type Hexagon Wrench...
Selecting the Mounting Area For proper heat dissipation, allow a clearance of approximately 500mm to the side, 500mm above and below the unit, and 1000mm to the front of the unit. DO NOT install the inverter in the following areas: Areas with high salt content, such as the marine environment.
If children under 10 years old may approach the unit, take preventive measures so they cannot reach and touch the unit. Install the indoor unit on the wall where the floor height is higher than 1600mm. Before connecting all wires, please take the metal cover off, removing the screws as shown below: Mounting the Inverter Select installation locations that are adequate to support the weight of the converter.
Inverter Hanging Plate Installation 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.

29.9/30/35/40/50KW model, the recommended AC breaker for grid is 240A. There are three terminal blocks marked as GRID, LOAD, and GEN. Please do not confuse input and output connections. External AC SPD is compulsory on all Sunsynk inverters. WARNING All wiring must be performed by qualified personnel. System safety and efficient operation need to use appropriate cable for AC input connection.
1. Switch the Grid Supply Main Switch (AC) OFF. 2. Switch the DC isolator OFF. 3. Assemble PV input connector to the inverter. 4. Use the MC4 connectors supplied by Sunsynk with the inverter. THREE PHASE HI 29.9/50kW | User Manual...

WARNING Before connection, please ensure the polarity of the output voltage of the PV array matches the DC+ and DC- symbols. Please do not connect the PV array's positive and negative poles to the system ground bar. This can seriously damage the inverter. Before connecting the inverter, please make sure the PV array open-circuit voltage is within the maxi- mum limit of the inverter.
Connecting the CT Coil The CT coil is one of the most important parts of the Sunsynk inverter. This device reduces the power of the inverter to prevent feeding power to the grid. This feature is also known as “Zero Export”.
NOTE: When the reading of the load power on the LCD is not correct, please reverse the CT arrow. When the inverter is in the off-grid state, the N line needs to be connected to the earth. For systems utilizing three or more inverters drawing over 300A from the grid, it's advisable to employ larger CTs (Current Transformers).

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. It is crucial to refer to the manuals that manufacturers produce for their batteries. That way, the chance of errors occurring during installation is significantly reduced.

Page 48
7. Grid peak shaving: When this is selected, the grid output power will be limited within the set value. If the load power exceeds the allowed value, it will take PV energy and stored battery energy to supple- ment. If there is not enough PV energy or stored energy to meet the load requirement, grid power will increase to meet the load needs.
Page 49
Zero Export to CT: The hybrid inverter will not only provide power to the backup load connected but also give power to the home load connected. If PV power and battery power are insufficient, it will take grid ener- gy as a supplement. The hybrid inverter will not sell power to the grid. In this mode, a CT is needed. For the installation method of the CT, please refer to the chapter "CT Connection".
Page 50
Example 2: The power produced is supplying the ‘Non-Essential Load’ while the inverter is set at a maximum power of 50kW (Max Sell Power). The inverter is connected to the grid, but no export is performed. The unit allows small amounts of power to flow from the Grid (100W Zero Export Power) to prevent any back-flow. In this example, the solar PV is prioritised to supply the Load first and then subsequently, charge the battery.
