A system is disclosed that includes an open-circuit voltage measurement device for measuring an open-circuit voltage of a string of solar battery panels in a state where the string and a load are not connected; a drive control device for controlling an output voltage of the solar battery panels; and a calculation control device for outputting a signal for controlling the drive control device so that the open-circuit voltage attains a predetermined voltage equal to or more than an operable voltage of the load but not more than a breakdown voltage of the photovoltaic power system, based on the open-circuit voltage measured by the open-circuit voltage measurement device when the string and the load are in an open state. |
