Abstract
The disclosure reduces the occurrence of an inrush current upon electrical connection of a storage cell, allowing immediate use. A power supply apparatus is configured to convert DC power from a solar cell and a storage cell into AC power and includes: a first capacitor disposed between the solar cell and the storage cell; and a controller configured to charge the first capacitor with power from the solar cell or a power grid and, after a first voltage of the first capacitor exceeds a second voltage of the storage cell, to electrically connect the storage cell with the first capacitor.
