An Inverter Generator electronically throttles the engine up and down to meet demand instead of running full tilt all the time. The resulting improvement in efficiency means that you won’t have to fill up the gas tank as often. Inverter generators also produce lower emissions and are generally very quiet.

These machines come at a premium price, but they run longer, quieter, and more efficiently. the generator’s alternator produces high voltage multiphase AC power. The AC power is then converted to DC. Finally the DC power is converted back to AC by the inverter. The inverter also smoothes and cleans the power to make it high quality. A special microprocessor controls the entire process, as well as the speed of the engine.
