Generac XG04045ANAC 40kW Liquid Cooled 1 Phase 120/240V Standby Generator

The Generac Model XG04045ANAC is a premium, high-capacity standby generator from Generac's Protector XG Series line. It is designed for continuous, whole-building backup power for large homes and demanding commercial or agricultural applications. This generator is distinguished by its industrial-grade, low-speed (1800 RPM), liquid-cooled engine, which maximizes durability, quietness, and fuel efficiency during extended operation. It provides continuous, reliable, and quiet whole-building backup power while meeting the most stringent environmental regulations.

Features

High Power Output:

  • Delivers a maximum continuous power of 40 kW on both Liquid Propane (LP) and Natural Gas (NG), suitable for backing up entire large buildings or complex commercial systems.

CARB/SCAQMD Emission Compliant:

  • The "C" designation means this unit meets the most stringent emission standards (CARB/SCAQMD), making it legally compliant for installation in regulated jurisdictions.

Low-Speed (1800 RPM) Operation:

  • Runs at half the speed of standard air-cooled units. This is the main feature that maximizes engine life, reduces engine noise, and ensures continuous, reliable operation during extended outages.

Industrial Liquid-Cooled Engine:

  • Powered by a robust 4.5L, 4-Cylinder engine. Liquid cooling ensures superior heat dissipation, making the unit reliable for indefinite, continuous periods.

True Power™ Technology:

  • Provides best-in-class power quality with less than 5% Total Harmonic Distortion (THD), crucial for protecting sensitive commercial and industrial electronics.
