Clearance
Ensure that there is a minimum of 400mm clearance space around the inverter.
Wall mounting
Be careful to avoid pipes and electrical cables when punching holes into the wall.
System overview
- You must consider the suitable positioning of the battery and the PV.
- You can choose CT or smart meter to connect to the inverter. If there are strict requirements on the limited export power, a smart meter is recommended.
Earth connection
Main earth connection should be connected to the grid tied terminal block.
Note : The earth bond point on the bottom of the inverter is designed for
connection to the battery and additional earth bonding.
Battery terminal connection
- Properly crimp ring terminals to power cables
- Ensure connection is tight and the ring terminal cannot move
PV connection
- Please make sure the PV input voltage/current isn’t beyond the specification
- When installing the PV terminal, pay attention to the positive and negative terminals and one-to-one correspondence between the terminals and inverter. Follow the labelling underneath the connection points
AC connection
- Grid tied connections are on the right-hand side
- If using the back-up connect on the left-hand terminals, ensure that you have sufficient overcurrent protection and sufficient earthing in place
