The total inductance should be determined based on the operating state of the photovoltaic inverter. The capacitance value should be limited so that the reactive power it generates does not exceed 5% of the system's rated power.
The best coupled inductance can then be determined by observing the minimum power loss from Pc (EUR). It is observed from Figs. 6 a and b that the best coupled inductances for 1.5 and 2.5 kW PV inverters are 3.58 and 2.92 mH, respectively.
