PROBLEM TO BE SOLVED: To provide a power supply device which can efficiently supply generated power and charging power to a load without interruption by a power generation state of a simple power supply device and a charging state of a storage battery in accordance with an operation state of the load.SOLUTION: A power supply device 10 performs: a first control mode for controlling generated power to be supplied to a load 6 when a solar battery panel 1 can supply power; a second control mode for controlling a storage battery 4 to be charged with remaining power of the generated power supplied to the load 6 when the generated power is larger than power consumption and the storage battery 4 can be charged at the first control mode; a third control mode for controlling the generated power of the solar battery panel 1 and discharged power from the storage battery 4 to be supplied to the load 6 when the solar battery panel 1 can supply power but the generated power is smaller than the power consumption and the storage battery 4 can discharge power; and a fourth control mode for controlling the discharged power from the storage battery 4 to be supplied to the load 6 when the solar battery panel 1 cannot supply power and the storage battery 4 can discharge power. The power supply device performs the modes by control of a main control section 21 and the like. |
