Generac XG08045 Protector Series 80kW 1-phase Generator Features:
Generac XG08045 80kW 1-Phase Protector Series Generator
The Generac XG08045 80kW 1-phase generator is a powerful liquid-cooled standby generator designed for large residential estates, commercial properties, agricultural operations, and light industrial applications. As part of Generac’s Protector® Series lineup, the generator continuously monitors incoming utility power and automatically starts during an outage, restoring electricity within seconds to keep critical systems operating.
With 80kW of standby power in a 120/240-volt single-phase configuration, this generator is designed to support substantial electrical loads such as multiple HVAC systems, refrigeration equipment, pumps, lighting systems, and other high-demand appliances. This level of capacity makes the generator well suited for large homes, retail businesses, farms, and facilities that require more power than traditional residential standby generators.
The XG08045 is powered by a Generac 4.5-liter liquid-cooled inline four-cylinder engine with turbocharging and aftercooling, engineered for long service life and efficient operation during extended outages. Operating at 1,800 RPM, the generator provides reliable performance while maintaining stable electrical output. Generac’s True Power™ electrical technology delivers less than 5% total harmonic distortion and ±1% digital voltage regulation, ensuring utility-quality electricity that protects sensitive electronics and modern appliances.
Built for outdoor durability, the generator is housed in a corrosion-resistant aluminum enclosure with electro-galvanized baseframe components and a stainless-steel exhaust system. The system also includes Mobile Link™ remote monitoring with cellular connectivity and Wi-Fi backup, allowing users to monitor generator status, receive maintenance alerts, and confirm system readiness from a smartphone, tablet, or computer.
