Inverter track the GMPP?

[hugomoreira22]

I don't know this is the best forum for this question.

When a partial shading occurs on the string, and I define my modules on the string the module layout.

Does PVsyst consider that the inverter will track the best Maximum Point (Global maximum power point)?

Thank you,

Yes, in the simulation the inverter chooses the best MPP (which is not necessarily the case in the reality).

However this best MPP voltage is often lower than the Minimum voltage for MPP tracking, so that the simualtion will choose the better power between the secondary MPP and the power at the VmppMin. This is visible in the plot showing the I/V curves in the Module Layout tool.
