Inverter Selection and Fan Speed Control

Where there is a single phase supply the inverter can convert the single-phase supply to three-phase power. Single -three phase inverters will take a 230V single phase supply and convert it to a 230V three phase supply to power a three phase fan. The correct selection of an inverter depends on the motor kW rating of the fan, the inverter has to
