Abstract:
1. A method of controlling a photovoltaic inverter for variable-speed controlling a motor with solar cells as its power source comprising a step of starting up the motor by supplying a start-up power through the photovoltaic inverter from said solar cells while monitoring the output power and voltage of said solar cells, a step of storing the voltage value of the solar cells as a reference voltage (V a step of continuing accelerating until the voltage of the solar cells shifts from said reference voltage (V a step of, after the voltage of the solar cells reached the first voltage (V a step of, after this deceleration operation is over, when the voltage of the solar cells is within the given allowable voltage regulation range (Hb) with reference to said reference voltage (V
