Inverter Overload design

[makara]

In case, we operate the inverter overload. does it effect to warranties of the products?

This depends on the Manufacturer's conditions of course.

To my opinion, if the inverter is correctly designed, there is no reason for limiting the nominal power of the connected PV array, because the power limitation is ensured by the inverter itself, by displacing the operating point on the I/V curve.

Now if this condition is marked as contractual in the datasheets, you have to observe it of course. You have a checkbox in the PVsyst definition of the inverter, indicating whether the condition is contractual or not. If checked, PVsyst will not allow to design a system overcoming this condition.
