Generac XG04845C Protector Series 48kW 3-phase Generator (SCAQMD Compliant) Features:
Generac XG04845C 48kW 3-Phase Generator
The Generac XG04845C is a top-tier 48kW 3-phase automatic standby generator engineered to deliver dependable, utility-grade power in complex commercial and industrial settings. Built with long-term reliability and intelligent management in mind, this generator pairs high-output performance with advanced monitoring and control, all housed in a corrosion-resistant, quiet-operating enclosure.
Powering the system is a 4.5L liquid-cooled Generac inline 4-cylinder engine, running at an efficient 1800 RPM. Designed to run on either natural gas or propane, the unit allows for seamless fuel selection through the onboard controller—no manual hardware switches required. This naturally aspirated engine supports continuous operation at full load with excellent fuel economy, consuming 6.6 gallons/hour of LP or 604 cubic feet/hour of NG.
The XG04845C’s Power Zone® 410 digital controller is the brain of the system, offering real-time diagnostics, programmable settings, and full 3-phase monitoring. The multilingual, full-color interface provides instant access to voltage, current, fuel pressure, engine temperature, load data, and more. With built-in Mobile Link™ cellular connectivity, you can manage and monitor the generator remotely from any web-connected device.
This generator is capable of outputting across configurable voltages: 208/120V, 240/120V, or 480/277V 3-phase, using optional Voltage Configuration Cartridges (VCC). Whether for small industrial campuses, large commercial buildings, or critical service facilities, the XG04845C offers flexible voltage adaptability for a broad range of applications.
The system is UL 2200 listed, EPA certified, and compliant with California and Massachusetts emissions regulations. The enclosure is wind-rated to 145 mph and built from aluminum with a RhinoCoat™ powder finish, offering resistance to corrosion, salt, and severe weather. Sound output stays near 67 dB(A) at 23 feet, with even quieter operation during self-testing thanks to Quiet-Test™ low-speed exercise mode.
A wide range of optional accessories is available, including emergency stop switches, cold weather kits, annunciators, and seismic anchoring systems, enabling customization for highly regulated or mission-critical environments.
