4.5. Grid connection and backup load connection
Before connecting to grid, please install a separate AC breaker between inverter and grid.
Also, it is recommended that installs an AC breaker between backup load and inverter.This will
ensure the inverter can be securely disconnected during maintenance and fully protected from
over current. For the 25/30/40/50KW model, the recommended AC breaker for backup load is
180A. For the 25/30/40/50KW model, the recommended AC breaker for grid is 180A.
There are three terminal blocks with "Grid" "Load"and "GEN" markings. Please do not miscon-
nect input and output connectors.
All wiring must be performed by a qualified personnel.It is very important for sys-
tem safety and efficient operation to use appropriate cable for AC input connec-
tion. To reduce risk of injury, please use the proper recommended cable as below.

Grid Connection
Please follow the steps below to implement GRID, LOAD, and GEN port connections:
1. Before making GRID, LOAD, and GEN port connections, make sure to turn off the AC
breaker or disconnector first.
2. Remove insulation sleeve 10mm length, insert the wires according to polarities indicated
on the terminal block. Make sure the connection is complete.Then, insert AC output wires
according to polarities indicated on the terminal block and tighten the terminal. Make sure
to connect corresponding N wires and PE wires to related terminals as well.
3. Then, insert AC output wires according to polarities indicated on the terminal block and
tighten terminal. Be sure to connect corresponding N wires and PE wires to related termi-
nals as well.
4. Make sure the wires are securely connected.
