  1. Dear developer team, I hope my message finds you very well, I have an question which is so urgent please. This simulation I have been doing is critical to the point that many decisions will be taken on for this already running PV system. I'm acting as a consultant for this system hence results and its explanation is important. My question is why for this project (project file and PDF simulation report are attached) the losses due to down regulation on the account of mpp voltage is so high? it represents almost 9% of the annual losses? I can see that the operating voltage is operati
  2. Good morning, I am considering the following configuration of 5 strings of 18 modules each with the 20KTL Huawei inverter and AC-300M/60S modules: That is, not the typical configuration of two identical strings per MPP, as the current would be too high: I understand that the first configuration is possible, but I'm not sure how the connection would be done in the "real world". Would it be a string per MPP input entrance, leaving the sixth unused? How would the inverter know I'm not following the second configuration, which is not allowed?
  3. Hello everyone, I would like to ask a question about the losses about regulation on account of MPP Voltage Range. Actually I work on effect of MPP range on total energy yield and now I use trial version of PVSOL to check whether the software gives expected results or not. Minutely simulations are supposed to seize the instantaneous voltage drops on PV arrays due to momentary low irradiance values that exist quite frequently in cloudy weathers. So inverters whose MPP range extends towards lower voltages can keep operating with relatively high efficiencies compared to the inverters with narro
