The Generac XG Protector Series liquid-cooled standby generators deliver premium, code-compliant power protection for large residential and commercial applications. Engineered and assembled in the USA, these units are powered by a purpose-built 2.5L inline 4-cylinder engine that features intelligent proprietary controls for optimized fuel efficiency across varying temperatures and elevations. Driven by the advanced Power Zone 410 controller, the series offers seamless fuel choices between natural gas and liquid propane, which are selectable directly at the controller. With a robust wind-speed rating up to 145 mph, a corrosion-resistant aluminum enclosure, and ultra-quiet operational modes, these generators guarantee quiet, reliable backup performance without property disruption.
