Abstract

According to an embodiment, a power supply system includes a power storage unit, a changeover unit, and a control unit. The power storage unit is configured to store electric power generated by a power generation unit. The changeover unit is configured to make a changeover between a first state in which a load is connected to the power generation unit and a second state in which the load is connected to the power storage unit but not the power generation unit. The control unit is configured to perform control to make the changeover to the first state when a value obtained by subtracting a first value from a value of the electric power fed from the power generation unit is not less than a value of the electric power fed to the load. Otherwise, the control unit is configured to perform control to make the changeover to the second state.
