"The inverter power is strongly oversized" error on all projects (new and old)

[diegogto]

Hi,

I am getting the "The inverter power is strongly oversized" error on all projects (new and old), no matter they are correct or not. I have all hidden parameters in default and no matter which inverter/module combination I use, it always show that error unless it is triggered from some other error, as "inverters undersized" for example.

Should I need to reinstall?

Which PVsyst version?

Under Hidden parameters > Verifications on Grid Systems,

• set "Inverter power is strongly oversized" to 0.1 ratio

• set "Limit overload loss for design" to 60%
