Abdel Posted February 4, 2022 Share Posted February 4, 2022 Hi folks Regarding to ohmic losses. I have system consists of 120Kwp (PV modules) and 100KW inverter power. The system consists of 18 PV strings , 18 PV modules per string. I want to connect directly 18 strings on 10 MPPTs/20 Inputs , which means that I don't need combiner box in the system. Now for ohmic losses , PVsyst define combiner box for the calculations and there is no option to skip it .My question , how I can calculate the power loss if I have for example 18 PV strings connected directly to the Inverter MPPTs inputs without combiner box in PVsyst ? ?
