Abstract
A system and method for controlling the DC voltage provided to a PV inverter is disclosed. A PV system includes a pair of PV array group configured to generate a direct current (DC) output from received solar irradiation and a DC-to-AC power inverter electrically coupled to the pair of PV array groups to receive the DC output therefrom and invert the DC output to an AC output. The PV system also includes a switching element positioned between the pair of PV array groups and the DC-to-AC power inverter, with the switching element being configured to selectively connect the pair of PV array groups to the DC-to-AC power inverter in one of a series arrangement and a parallel arrangement, so as to control a level of DC voltage received by the DC-to-AC power inverter from the pair of PV array groups.
