Generac XG04045ANAX 40kW 120/240V Standby Generator

Generac XG04045ANAX – 40kW 120/240V Standby Generator

The Generac XG04045ANAX is a 40kW liquid-cooled automatic standby generator designed for backup power applications using 120/240V 1-phase service. This Protector gaseous generator supports natural gas or vapor propane fuel and is part of the Liquid Cooled XG Series. The supplied product data lists this model with no catalyst option and notes that it is not available for purchase in California or Massachusetts. With Quiet-Test Self-Test Mode, TruePower technology, controller-selectable fuel, cellular connectivity, and corrosion-resistant construction, this generator supports standby power planning when properly sized and professionally installed.

40kW Backup Power for 120/240V 1-Phase Applications

The XG04045ANAX is built for standby generator projects where 40kW output, 120/240V 1-phase service, and fuel flexibility are key requirements. Final load sizing, voltage requirements, fuel setup, RPM, catalyst requirements, and site conditions should be reviewed before placing an order.

No-Catalyst Configuration for Non-CA/MA Applications

This ANAX 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 Self-Test Mode and TruePower Technology

Quiet-Test Self-Test Mode runs at a lower RPM for a five-minute test cycle and can be programmed weekly, biweekly, or monthly. TruePower technology is listed to deliver less than 5% total harmonic distortion for clean, smooth power quality.

Controller-Selectable Fuel and Corrosion Resistance

This generator supports controller-selectable fuel setup for natural gas or vapor propane. The supplied details also list an aluminum enclosure, zinc-plated fasteners, and electro-galvanized frame rails with powder coat for corrosion resistance in demanding outdoor environments.

The Generac XG04045ANAX is designed for permanent standby generator applications where 40kW output, 120/240V 1-phase service, and no-catalyst configuration are part of the project requirements. Its controller-selectable fuel setup helps support natural gas or vapor propane planning for the site.

With Quiet-Test Self-Test Mode, TruePower technology, cellular connectivity, and corrosion-resistant construction, this generator supports practical standby power planning and long-term service visibility. This no-catalyst model should be reviewed carefully for state-specific emissions requirements before ordering.
