Generac XG08045 Protector Series 80kW 3-phase Generator Features:
Generac XG08045 80kW 3-Phase Protector Series Generator
The Generac XG08045 80kW 3-phase generator is a commercial-grade standby generator engineered to provide dependable backup power for industrial facilities, commercial buildings, agricultural operations, and mission-critical infrastructure. As part of Generac’s liquid-cooled Protector® Series, this generator continuously monitors utility power and automatically starts when an outage occurs, restoring electricity in seconds to keep essential equipment and operations running.
With 80kW of standby power and configurable 3-phase voltage output, the XG08045 is built for facilities that operate heavy electrical loads across multiple phases. This makes it ideal for running commercial HVAC systems, pumps, elevators, refrigeration equipment, manufacturing machinery, and other motor-driven systems that require balanced three-phase power distribution.
The generator is powered by a Generac 4.5-liter liquid-cooled inline four-cylinder engine with turbocharging and aftercooling, engineered for durability and fuel efficiency during extended outages. Operating at 1,800 RPM, the system delivers reliable performance while minimizing engine wear. Generac’s True Power™ electrical technology produces less than 5% total harmonic distortion with ±1% digital voltage regulation, delivering utility-quality electricity that protects sensitive electronics and microprocessor-based equipment.
Every XG08045 3-phase generator ships configured for 208/120V three-phase output, but installers can easily change the voltage to 240/120V or 480/277V using Generac’s Voltage Configuration Cartridge (VCC). This flexible design allows the generator to match a wide range of commercial electrical systems while simplifying installation and reducing the need for specialized wiring changes.
The generator is protected by a corrosion-resistant aluminum enclosure with electro-galvanized baseframe components and a stainless-steel exhaust system, ensuring long-term durability in outdoor environments. It also includes Mobile Link™ cellular connectivity with Wi-Fi backup, allowing owners to monitor generator status, receive maintenance alerts, and verify system readiness remotely.
