3.4 Grid connec�on and backup load connec�on
· Before connec�ng to the grid, a separate AC breaker must be installed between the inverter
and the grid, and also between the backup load and the inverter. This will ensure the inverter
can be securely disconnected during maintenance and fully protected from over current. The
recommended of AC breaker for the load port is 63A for 8kW, 63A for 10kw and 63A for 12kW.
The recommended of AC breaker for the grid port is 63A for 8kW, 63A for 10kw and 63A for 12kW.
· There are three terminal blocks with "Grid" "Load"and "GEN" markings. Please do not misconnect
input and output connectors.
All wiring must be performed by a qualified personnel.It is very important for
system safety and efficient opera�on to use appropriate cable for AC input
connec�on. To reduce risk of injury, please use the proper recommended cable
as below.

Please follow below steps to implement Grid, load and Gen port connec�on:
1. Before making Grid, load and Gen port connec�on, be sure to turn off AC breaker or
disconnector first.
2. Remove insula�on sleeve 10mm length, unscrew the bolts, insert the wires according to
polari�es indicated on the terminal block and �ghten the terminal screws. Make sure the
connec�on is complete.
