Abstract
In a case where it is determined that a generated electric power of a solar panel is less than a predetermined value, a control unit of a solar photovoltaic generation device is configured to disconnect a solar battery from a first electric power conversion unit and a second electric power conversion unit, stop providing a power supply to the first electric power conversion unit to execute a power saving control, and store an open circuit voltage of the solar panel as a reference voltage after the execution of the power saving control. In a case where the open circuit voltage of the solar panel exceeds the reference voltage continuously for a predetermined time period after the execution of the power saving control, the control unit is configured to connect the solar battery to the first electric power conversion unit and the second electric power conversion unit, and start providing the power supply to the first electric power conversion unit to release the power saving control.
