Abstract
DC supply circuitry is disclosed to supply DC power from an AC source to a DC PV panel input associated with a PV energy storage system (ESS) inverter system. The DC power may be supplied in accordance with a DC current and DC voltage. The DC PV panel input may function by adjusting the drawn current that is supplied by the DC supply circuitry based upon changes in the load, e.g. battery charging. The DC supply circuitry may function to adjust the supplied DC voltage in accordance with changes in the drawn current using a corresponding point on a predetermined DC voltage current-voltage characteristic (I-V) curve. The predetermined I-V curve may represent an ideal I-V curve associated with a DC PV panel system that is compatible with the PV ESS inverter system, thereby allowing for the use of DC PV panel inputs that may typically go unused.
