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 5 holes
from the bracket.
Drill holes with an electric drill, make sure the holes are at
least 50mm deep, and then tighten the expansion tubes. 
Insert the expansion tubes into the holes and tighten them. Install the
bracket with the expansion screws. 
Step 2: Match the inverter with a wall bracket

| Cable | 2.∼5 6mm² | 4∼6 6mm² | 6∼10mm² | 10∼mm² | |||||||
| Micro-breaker 1 | 16A | 25A | 40A | 50A | 60A |
Trim all the wires to 52.5mm and the PE wire to 55mm.
Use the crimping pliers to trim 12mm of insulation from all wire ends as shown
in the picture.
Note: Please refer to local
cable type and color for the actual installation.
Separate the AC plug into three parts.
Insert the sleeve assembly into the cable.
Install the copper wire into the plug terminal and lock the screw.
Lock the lock nut and the sleeve(35N·m), lock the sleeve and the
plug(1.51.7N·m). Insert the plug assembly into the socket (inverter end) and
lock each other by the coupling twist.
DC Wiring
Turn off the DC switch.
Choose 12 AWG wires to connect the PV module.
Trim 6mm of insulation from the wire end. 
Separate the DC connector as below.
Insert the stripped cable into pin contact and ensure all
conductor strands are captured in the pin contact.
Crimp pin contact by using a crimping plier. Put the pin contact with striped
cable into the corresponding crimping pliers and crimp the contact.
Insert pin contact through the cable nut to assemble into the back of the male
or female plug. When you feel or hear a “click” the pin contact assembly is
seated correctly. 
Grounding Wiring
Screw the ground screw with a screwdriver as shown below. 
Startup
Procedure
1. After checking all connections are correct, turn on the external DC /AC
breakers.
2. Turn the DC switch to the “ON” position.
3. Inverter will start automatically when PV panels generate enough energy,
the LED will be green.
