In an inverter control device that detects the output voltage of a solar cell and is equipped with a frequency setting circuit that controls the output frequency of an inverter that operates a load with multiplication reduction torque characteristics at a predetermined frequency based on a frequency command signal. Then, a DC/DC converter converts the frequency command signal into a correction signal level and compares the above frequency command signal with the above correction signal as a first frequency command signal, and if the output of the solar cell decreases, the inverter A small priority circuit that outputs a second frequency command signal corresponding to the output voltage of the device that lowers the upper limit output frequency is provided, and the frequency and voltage of the inverter are controlled based on the second frequency command signal. An inverter control device characterized by:
