Hello,
I would like to know if and how PVSYST manages the MPPT efficiency i.e. the ability of the inverter to follow MPP. I suppose it depends on inverter MPPT algorithm, sampling frequency, global and local MPP etc...
Does PVSYST include this MPPT efficiency in inverter .OND model?
If not, what is in your opinion the pecentage losses attributable to the MPPT in-efficiency?

thanks a lot

PVsyst doesn't take the MPPT tracking losses into account.
This is extremenly dependent on the inverter's technology, and the manufacturers never (or almost never) give information about this performance.
If you want to take it into account, you have to include this loss in the inverter's efficiency.

Thanks,
does someone has guidelines to quantify this additional loss?
