Abstract
A power storage system includes an electric power conversion apparatus, an electric power generation source, and a power storage unit. The power storage unit is configured to have a stored power voltage equal to or higher than a first control voltage to be given to a control unit, the first control voltage being necessary for electric power conversion operation by a DC-DC converter in the electric power conversion apparatus. The control unit in the electric power conversion apparatus is configured to start operating and control an operation of a first switch, when a generated power voltage of the electric power generation source reaches a second control voltage lower than the first control voltage.
