PV Connection
The inverter has two PV inputs and can be configured in independent mode or
parallel mode. Refer to the user manual for mode selection.
Before connecting the PV arrays to the inverter, ensure that the impedances
between the positive terminals of the PV string and Earth, and between the
negative terminal of the PV string and Earth are larger than 200 kOhm.
The inverter will not function properly if the DC polarities are reversed.
Check the positive and negative polarities of the PV cells.
