Hello,

We have been working with some of our manufacturers and we have realized that the auxiliary consumption of the inverters at 50° can have an additional impact of up to -0.5% in the output energy compared to the consumption at 25°.

Similarly, the efficiency of inverters may vary around - 0.3% / - 0.4% depending on their temperature.

As the inverters' characteristics are studied at 25°by norm, the simulation could be almost +1% off in the PR just due to the effect of the temperature on the efficiency and auxiliaries of the inverters.

I think it would be a gain in precision to modify the .ond to integrate a dinamic correction of the auxiliaries and the efficiency of the inverters.

Thank you,
Enrique Trabajo.
