Requirements for the PV modules per input
All PV modules should be of the same type.
All PV modules should be aligned and tilted identically. Otherwise the yields may be reduced.
If 2 strings are connected to one input, the same number of PV modules wired in series should be connected to each string. Otherwise the yields may be reduced.
On the coldest day based on statistical records, the open-circuit voltage of the PV array must never exceed the maximum input voltage of the inverter.
The maximum input current per string must not be exceeded, and must not be greater than the rated through-current of the DC connectors.
The thresholds for the input voltage and the input current of the inverter must be adhered to.
