In order to couple a solar inverter with a PV plant, it's important to check that a few parameters match among them. Once the photovoltaic string is designed, it's possible to calculate the maximum open-circuit voltage (Voc,MAX) on the DC side (according to the IEC standard).
The input section of the inverter is represented by the DC side where the strings from the PV plant connect. The number of input channels depends on the inverter model and its power, but even if this choice is important in the plant design, it does not affect the inverter operation.
The second important check is the short circuit current match. It's important to ensure that the maximum short circuit current of the PV field is lower than the maximum current allowed by the inverter. This rule is valid for each inverter input. ISC, MAXPV < IDC, MAXINV
