PURPOSE:To reduce the initial cost and to decrease the running cost of a solar battery utilizing system by using a commercial power source at the time of starting a load and switching to the operation of a solar battery after becoming in normal state. CONSTITUTION:A controller 7 closes a contact 9 ON by an input of an operation start signal of an input terminal 8 and supplies a commercial power source 5 to an inverter 6 to energize a motor 2 by the starting current of the motor 2. After the prescribed time, the controller 7 opens the contact 9 OFF, and connects the contact 10 to a solar battery 1 side. Since the load 2 is started by the commercial power source and energized by the solar battery 1 after starting, the solar battery which requires high cost and installing plate can be reduced. |
