kjs55 Posted October 27, 2020 Share Posted October 27, 2020 Hi:PVsyst v6. Please add MPPT Efficiency to the list of "Contractual specifications, without real physical meaning" in the .OND file.This value is commonly reported on datasheets, etc. It relates to unavoidable losses from oscillations about the knee of the power vs. voltage curve (e.g., due to granularity limitations from both component/hardware choices and software algorithms--these losses are unavoidable even with an ideal curve). It would be good to keep track of the nameplate value in an inverter's .OND file.Thanks. Link to comment Share on other sites More sharing options...
