Hello folks, I have been reading some topics in the forum but I did not achieve to a final conclusion regarding the understanding of how PVSyst uses inverters temperature in the simulation.
1. In the OND file it is informed pretty much points combining Temperature and Power. The temperature informed is the Ambient Temperature or the Inverter's Temperature?
2. On Energy Management -> Inverter Temperature. There are 3 options:
a) Ambient temperature on exterior - Does it consider a perfect cooling of the inverter? Hence the inverter is always operation unders the ambient temperature?
b) This one is pretty clear, adding a extra fixed temperature on top of the ambient temperature. OK
c) Pretty much ok too. The inverter temperature varies according to the PV power input. Is there any usual number that could be used for reference either for central and string inverters?
My final question is:
If the temperature informed on the OND file is related to the ambient temperature, how does PVSyst considered the heating deagrading on the inverter?
But if the temperature informed in the OND is the Inverter's temperature, how does PVSyst estimates the inverter's temperature?
Finally, for my real case scenario, a PV plant in Brazil in a hot location (28ºC to 40ºC). What is the proper way of running simulations that considers temperature degrading on the inverter?
