PROBLEM TO BE SOLVED: To effectively use generated electric power even if the electric power generated by solar panels is little.SOLUTION: A power source controller 90 includes: an input part 91 where direct current is input from a PV array 5; a connection circuit 100 connected between a rectifier 81 and an inverter 82 in a power source portion 80 of an air conditioner; an output part 94 that outputs the direct current to an LED illumination 6 operating at a voltage lower than the minimum value of the output voltage of the rectifier 81 necessary for driving a compressor of an air conditioner; and a switch portion 104 that flows the direct current to both the output part 94 and the connection circuit 100 from the input part 91 when an output voltage of the rectifier 81 is lower than an output voltage of the PV array 5 while the direct current is flowed to the output part 94 from the input part 91 when the output voltage of the rectifier 81 is higher than the output voltage of the PV array 5. |
