A single phase inverter, or Variable Frequency Drive (VFD) is used to vary the power supply to an AC motor, allowing the speed of the motor to be controlled (hence why they are often called AC motor inverters). Our range of single phase inverters for sale are suitable for a huge range of industrial, commercial and domestic motors, particularly for fans and pumps where an AC motor running at full speed is not required. AC motor inverters can reduce the energy usage of some motors by as much as 50%, meaning that the inverter price can rapidly be recouped. Browse our range of single phase inverters below, all available with fast dispatch, free shipping and 30-day returns. If you aren’t sure on anything you can get in touch with our specialist team and we’ll be able to help.
