Generac XG04845 Protector Series 48kW 3-phase Generator Features:
Generac XG04845 48kW 3-Phase Generator
The Generac XG04845 3-Phase Generator from the Protector® Series delivers an impressive 48kW of standby power, engineered to serve commercial buildings, multi-load facilities, and large estates with complex electrical needs. Its 3-phase output options, high motor-starting capacity, and advanced diagnostics make it a robust solution for seamless operation in critical applications.
Powered by a 4.5L liquid-cooled Generac inline 4-cylinder engine, this model runs at 1800 RPM for optimal fuel efficiency, low noise, and extended engine life. The unit is equipped with True Power™ Technology, producing <5% total harmonic distortion, ensuring clean, utility-grade electricity that’s safe for sensitive electronics and variable-speed HVAC systems.
One of the highlights of the XG04845 is its fully integrated Power Zone® 410 controller—a full-color, multilingual digital interface that provides real-time access to engine diagnostics, load status, fuel levels, and performance metrics. The system supports 3-phase voltage sensing and allows for easy configuration between 208/120V, 240/120V, or 480/277V, using optional Voltage Configuration Cartridges (VCCs). Whether for retail, light industrial, or healthcare support, this flexibility supports diverse power needs.
Mobile Link™ connectivity is built in, allowing users or service providers to remotely monitor the generator's operation, receive alerts, and access maintenance history from any smartphone or PC. Coupled with optional field-installable accessories such as annunciators, emergency stop switches, and cold-weather kits, the XG04845 adapts to your environment and operational priorities.
Its corrosion-resistant aluminum enclosure, electro-galvanized base, and stainless steel exhaust system ensure it holds up in harsh climates. Rated to withstand 145 mph winds, the enclosure also keeps operational noise levels impressively low—in the low 60s dB(A) at 23 feet, depending on load and configuration.
The generator consumes about 6.6 gallons per hour of propane or 604 cubic feet per hour of natural gas at full load, offering efficient performance even at peak output. It includes a sealed bearing alternator, belt-driven cooling system, and a controller-selectable fuel source, making installation and operation streamlined and reliable.
