Q1： How to calculate the PV module quantity in series and parallel for DC input of String Inverter?
A PV module parameter, inverter parameter and temperature & conditions of installation area, these 3 aspects shall be considered together and conclude the result. About parallel quantity, avoiding useless wire, we shall put all input wires into the circuit to make sure maximum using of inverter. About series quantity, we shall make sure that the total voltage of all modules in the maximum series shall not be higher than the maximum DC input voltage which allowed by inverter. The total voltage of all modules in series will be great influenced by the module parameter and temperature & conditions of installation area. We shall deal with problems case by case. For example, the common 60-piece polysilicone component, the inverter using temperature is between -25 and 60℃, the parallel quantity of 600V DC input is between 9 and 13 pieces, of 1000V DC input is between 18 and 22 pieces.
