Ries_Kieszon Posted January 14, 2019 Report Share Posted January 14, 2019 Hello there, I am trying to design a system using SMA Core 1 inverters in combination with Trina 270/275/280 panels to clear our remainders. When I simulate the system there is no problems at all untill I open the "Performance Ratio (PR) per inverter" tab and notice the following. Inverter 1: average PR of 45% Inverter 2: N.A.N. Inverter 3: average PR of 88% Inverter 4: average PR 32% Inverter 5: N.A.N. (image added) To me it feels there is something off with either the system I've configured or with the PV-sol itself in this case, Can anyone give me any pointers where to look and or how to deal with the situation?
