miikaelopes Posted March 16, 2017 Share Posted March 16, 2017 Hi,I have a 1MW installation, in which we are facing high temperatures on equipments, we are looking to install a refrigeration system but we want to take into account the profitability of this update, so i was looking to run a PVsyst that i would input the airconditioners consumption and the power derating of inverters in case of heat. there is any method to do this inside PVsyst or not?Best regards Link to comment Share on other sites More sharing options...
André Mermoud Posted March 22, 2017 Share Posted March 22, 2017 The power derate of PNom(ac) as function of the temperature may be specified in the inverter's definition. The fan's consumption should be specified as "Auxiliary Loss" (in the "Detailed losses part).The inverter temperature conditions during the simulation may be specified in the "Miscellaneous tools" part.

david.zar Posted June 15, 2017 Share Posted June 15, 2017 André,If we selected in "Miscellaneous tools" one option, Does the program calculate the temperature derating with the meteorological information if the .ond has the information? Link to comment Share on other sites More sharing options...
