Improper operation during the wiring process can cause fatal injury to
operator or unrecoverable damage to the inverter. Only qualified personnel
can perform the wiring work.
All electrical installations must be in accordance with local and national
electrical codes.
All cables must be firmly attached, undamaged, properly insulated and
adequately dimensioned.
Note
Read and follow the instructions provided in this section while observing all
safety warnings.
Always note the rated voltage and current defined in this manual. Never
exceed the limits.
4.4.1 Grid connection
It’s very important for system safety and efficient operation to use
appropriate cable for grid (utility) connection.
Before connecting to the AC grid, please install separately an AC circuit breaker (250V/20A
recommended) between the grid and inverter.
To reduce risk of injury, please use the suggested cable requirement for AC wire as below:
