3. Assemble PV input connector to the Inverter.
Check whether the polarity of the connecting cable of the photovoltaic
string is correct, and ensure that the open circuit voltage under any
condition does not exceed the upper limit of the inverter input value of
600V.
Please don't connect PV array positive or negative pole to the ground, it
could cause serious damages to the inverter.
Before connection, please make sure the polarity of the output voltage of
PV array matches the "DC+" and "DC-" symbols.
