DC Wiring

• Turn off the DC switch.
  Choose 12 AWG wire to connect the PV module.

• Trim 6mm of insulation from the wire end.

• Separate the DC connector as below.

Inverter Installation

Please make sure the inverter will be installed at a proper distance as shown below.

1. Step 1: Fix the bracket on the wall Choose the place you want to install the inverter. Place the bracket on the wall and mark the position of the 3 holes from the bracket.
2. Drill holes with an electric drill, make sure the holes are at least 50mm deep, and then tighten the expansion tubes.
3. Insert the stripped cable into pin contact and ensure all conductor strands are captured in the pin contact.
4. Crimp pin contact by using a crimping plier. Put the pin contact with striped cable into the corresponding crimping pliers and crimp the contact.
5. Insert pin contact through the cable nut to assemble into back of the male or female plug. When you feel or hear a “click” the pin contact assembly is seated correctly.
6. Unlock the DC connector
7. Use the specified wrench tool.
8. When separating the DC + connector, push the tool down from the top.
9. When separating the DC – connector, push the tool down from the bottom.
10. Separate the connectors by hand.
11. Insert the expansion tubes into the holes and tighten them. Install the bracket with the expansion screws.
12. Step 2 : Match the inverter with the wall bracket Hang the inverter over the bracket, slightly lower the inverter, and make sure the two mounting grooves on the back are properly fixed with the two bracket bars.
