kjs55 Posted August 21, 2019 Share Posted August 21, 2019 (edited) PVsyst v6.83: I see a Hidden Parameter for "Maximum PnomRatio for inverter sizing" but not for "Minimum PnomRatio for inverter sizing". Is there a technical reason why the latter is missing? Is there some other way to set the latter using some other parameter(s) in PVsyst (hidden or not)?

dtarin Posted August 21, 2019 Share Posted August 21, 2019 My guess is that it has to do with equipment safety and protecting the inverters. A low pnom ratio might not function the most efficiently, but I dont think it's going to break the inverter, whereas too high of a pnom ratio can. Most inverter manufacturers only list max ratios (when they do list them) and not min ratios. Link to comment Share on other sites More sharing options...
