PROBLEM TO BE SOLVED: To enable preferential supply of power to load devices requiring the supply of power in supplying power to the load devices from a photovoltaic power generation device, and enable presentation of the state of power supply to the load devices to a user.SOLUTION: In a DC power supply system 1, a switch unit is arranged, in a power supply path, at a position to divide a power supply range to which a power from a photovoltaic power generation device 4 is supplied and a non-power supply range to which a power is not supplied. A switch control unit 62 controls the opening and closing state of the switch unit, and in setting the power supply range to which a power from the photovoltaic power generation device 4 is supplied, sets the power supply range so as to supply power in order from a load device having the highest priority on the basis of information on priority for the load devices L11 to L16 held in a priority holding unit 63. The switch control unit 62 displays the state of power supply in the power supply path on a control panel 64. |
