40,000 Watts. 4.5L Liquid-Cooled Engine. Complete Estate Protection.
The Generac Protector Series 40kW (Model XG04045ANAX) provides the ultimate peace of mind for large residential estates and commercial properties. This high-capacity 1-phase unit senses a power loss and restores electricity automatically, handling massive electrical loads including multiple central AC units and medical equipment. With TruePower™ Technology, it delivers utility-grade power quality with less than 5% total harmonic distortion for the safe operation of your most sensitive electronics.
Industrial Strength Engineering
Powered by a heavy-duty, purpose-built 4.5L 4-cylinder in-line engine, the 40kW Protector Series is designed for reliability in the most demanding conditions. It features a dual-valve ultra-low pressure fuel delivery system that ensures peak efficiency. Maintenance is a breeze thanks to the Single-Side Access design, allowing all regular service points—from oil filters to coolant—to be reached from a single side of the enclosure.
Advanced Corrosion Protection
Ideal for coastal and harsh environments. This unit features an all-aluminum enclosure, electro-galvanized steel frame components, and a stainless-steel exhaust system to resist rust and wear for years to come.
Smart Monitoring & Control
Includes FREE Mobile Link™ Cellular Connectivity. Monitor your generator's status from anywhere in the world using your smartphone. Receive maintenance alerts and status updates in real-time.
