Generac XG04845CNAX 48kW 3-Phase Standby Generator

Generac XG04845CNAX – 48kW Liquid-Cooled 3-Phase Standby Generator

The Generac XG04845CNAX is a 48kW liquid-cooled automatic standby generator designed for backup power applications using 3-phase service. This model supports 208/120V 3-phase output and can be configured for 240/120V or 480/277V 3-phase applications with optional Voltage Configuration Cartridges. It uses a 4.5L engine operating at 1800RPM and supports natural gas or vapor propane fuel. The supplied product data lists this configuration with no catalyst option and notes that it is not available for purchase in California or Massachusetts. With Quiet-Test mode, cellular connectivity, TruePower technology, and corrosion-resistant construction, this generator supports practical standby power planning when properly sized and professionally installed.

48kW Backup Power for Configurable 3-Phase Applications

The XG04845CNAX is built for standby generator projects where 48kW output, 3-phase service, and voltage flexibility are important requirements. The supplied data lists 208/120V as the base configuration and notes configurability for 240/120V or 480/277V using optional Voltage Configuration Cartridges.

No-Catalyst Configuration for Non-CA/MA Applications

This CNAX configuration does not have a catalyst and is not available for purchase in California or Massachusetts based on the supplied product note. For CA or MA installations, select the correct catalyst-equipped model that matches the required voltage and phase configuration.

Quiet-Test Mode and Cellular Monitoring

Quiet-Test mode runs a lower-speed five-minute self-test that can be programmed weekly, biweekly, or monthly. Cellular connectivity supports Mobile Link monitoring for generator owners and Fleet visibility for supporting generator service teams.

TruePower Technology and Corrosion-Resistant Design

TruePower technology is listed to deliver less than 5% total harmonic distortion for cleaner power quality. The supplied details also note an aluminum enclosure, electro-galvanized steel and aluminum frame components, and a stainless-steel exhaust system for corrosion protection.

The Generac XG04845CNAX is designed for permanent standby generator applications where 48kW output, 3-phase service, and configurable voltage planning are part of the project. For 120/208V 3-phase applications, the supplied product note states that this unit comes with the appropriate Voltage Configuration Cartridge.

For RTS switch applications, the supplied product note states that the appropriate Phase Sense Kit is required for the 3-phase voltage. For 240/120V or 480/277V 3-phase applications, the appropriate Voltage Configuration Cartridge and circuit breaker must be selected for the system to function.
