Abstract :
This paper investigates the time behavior of over-irradiance events in which the photovoltaic (PV) array outputs more power than the rated power of the inverter. A new dynamic interpretation of such events is proposed and is compared to the conventional static viewpoint. Facts revealed under such dynamic view may lead to new guidelines for system integrators and inverter designers in both sizing and designing inverters. A way to extend overload operation time of inverters is also proposed.
