A separate DC circuit breaker with a minimum rating of 150A must be installed between the
inverter and the energy storage battery before connecting to ensure safe disconnection of the
inverter during maintenance.
Before connecting the PV panel to the DC terminal, please make sure the the polarity is correct.
Incorrect polarity connections may damage the inverter.
Please check the short-circuit current of the PV cell group. The total short-circuit current of the
photovoltaic battery pack should be less than the maximum DC current of the inverter.
Connect the positive and negative poles of the PV panel output to the positive (+) and negative
(-) poles of the photovoltaic inverter. Each PV port on the inverter can withstand 15A.
When PV is connected, the positive and negative of the same road should be connected to the
same PV terminal (for example, the positive is connected to the positive of PV1, and the
negative is connected to the negative of PV1).
When PV has only one set of string input, please do not mix input area A and B.
When PV panels are exposed to sunlight, there is high voltage. To reduce the risk of electric
shock, avoid touching live parts and handle connection terminals with care.
