ABSTRACT:
A compressor motor of an air conditioner is powered by A.C. power from an invertor. In a first mode of operation, the power comprises a combination of a commercial A.C. power source and a solar battery. In a second mode of operation, i.e., a cost-efficiency mode, the frequency of power supplied to the motor is varied to ensure that the motor is powered solely by power derived from the solar battery when such power is above a reference value.
