The new 18 kW model makes whole-house protection more affordable than ever before. With Generac's exclusive Quiet-TestT feature, and a standard all aluminum enclosure, the 18kW is also a tremendous value.

A high efficiency alternator and a 992 cc OHVI® engine, the 18 kW provides the performance of a larger liquid-cooled model for less money. The 18 kW has the power to provide whole house coverage, for many moderately sized homes.
