PV modules connected in series in each PV string must be of the same specification.
The maximum open-circuit voltage of each PV string must be always lower than or equal to
1000 V DC.
The maximum short-circuit current of each PV string must be always lower than or equal to
13 A.
The positive and negative terminals of PV modules must be connected to the positive and
negative DC input terminals of the inverter respectively.
During the installation of PV strings and the inverter, the positive or negative terminals
of PV strings cannot be connected with short-circuit.
The total output power of PV strings must be always lower than or equal to maximum input
power of inverter.
