Abstract
A power supply device includes a photovoltaic power generator, a secondary battery unit, a charger configured to supply power from the photovoltaic power generator to the secondary battery unit, a DC-AC power conversion circuit configured to convert a discharge output of the secondary battery unit into AC power, and a control device configured to control charging of the secondary battery unit based on a load power prediction obtained by a moving average of used power and an amount of power generated by the photovoltaic power generator and perform control to switch output of the amount of power generated by the photovoltaic power generator between the secondary battery unit and a commercial system power based on a value of state of charge (SOC) of the secondary battery unit.
