    Dear PVsyst Team, I need some clarification on the AC Losses portion, 1) AC Transformer Losses portion While defining the losses from the datasheet tab (6600kVA Nom.Power) 3 Nos of Trafo is used in the project so total Nom.Power will be 19800kVA. here, the point to be noted is that no value of temperature is being defined in PVsyst. Then, how the Nominal power at STC calculation is performed in internal pvsyst (at transformer side). 2) AC Wire Loss Inverter to Transfo Inverter ratting Nominal power at 50deg is 275kVA and as per the power vs temp curve (image is attached here for the reference) 20 deg to 30deg the power is 330kVA only Then, how the Nominal power at STC calculation is performed in internal pvsyst (at inverter side).
