S.F. Posted March 2, 2018 Report Share Posted March 2, 2018 Dear PV-sol experts, I have a question regarding the calculation of the dimension factor, influenced by the cos phi and the AC Power Rating of the inverter. 1. When using the Huawei SUN2000-36KTL inverter with the posted output specs, PV-Sol is taking the "Rated AC active Power" (from data sheet, picture 1) both as the "AC Power Rating [kVA]" and as the "AC Active Power [kW] (cos(phi)=1)". (picture 2) If i change the cos(phi) to 0,9, the "AC Active Power [kW] (cos(phi)=0,9)" changes regarding to that (picture 3) Actual question: It was my understanding, that the36KTL can bring up tu 40kVA apparent power, as seen in the data sheet. Shouldn't it be possible to use the 40kVA apparent power as active power in case of cos(phi)=1? Picture 1: Huawei SUN2000-36KTL inverter output specs Picture 2: Huawei SUN2000-36KTL PV-Sol dimension wit cos(phi)=1 Picture 3: Huawei SUN2000-36KTL PV-Sol dimension wit cos(phi)=0,9 Thanks for thinking!
