Unreal losses due to IL_Imax


Recommended Posts


After an update of PVsyst several projects that were working perfectly in previous versions, started to have losses due to overcoming the Inverter max current.

The issue just happens in the summer months, when the temperature and irradiance are higher (both increasing Isc).

The effect seems to be coherent but this is not happening in real life. Comparing a real project with the simulation the accuracy at "normal" days is very good. However when we have the "inver max current" issue the difference between real production and PVsyst simulations is huge (see image ... days highlighted in yellow)

I would appreciate any suggestion to solve this issue at the PVsyst simulation and to understand why it is happening.

Thanks and best regards,
