PURPOSE:To stabilize a maximum output by connecting or disconnecting a load to or from a solar battery circuit in accordance with the change of the voltage obtained from a solar battery to always fix the voltage so that the output is maximum. CONSTITUTION:Plural loads 2, 21, 22- are connected in parallel to a plus-side circuit A and a minus-side circuit B of a solar battery frame 1 through switches 3, 31, 32-. A controller 5 is connected between the first load 2 and a solar battery 4, and a voltmeter 6 is connected between circuits A and B. Switches 3, 31, 32- are switched by the controller 5 in accordance with the change of the voltage of the voltmeter 6 to change the number of loads, and the voltage is always fixed to obtain a maximum output. |
