Description

Please note: This generator is three-phase and not suitable for running large single-phase equipment such as welders and air compressors.

The Genmac Wonder 3-Phase Generator delivers stable, pure sinewave power with very low harmonic distortion, making it ideal for sensitive electronic equipment, including electronically controlled machinery. Designed and made in Italy, this generator combines robust construction, quiet operation, and advanced technology for reliable off-grid or backup power.

Economical, reliable generator with a powerful, fuel injected Honda petrol engine. Ideal for business and house backup where the mains supply is 3 phase and for running large 3 phase welders and other electronic controlled 3 phase machinery. Full protection from the elements with a galvanized steel canopy and a powder coated finish for ultimate durability. Pure sinewave & stabilized voltage makes this generator ideal for powering sensitive electronic equipment.
