Generac XG04845ANAX 48kW 120/240V Standby Generator

Generac XG04845ANAX – 48kW 120/240V Standby Generator with ecobee

The Generac XG04845ANAX is a 48kW 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 listed with no catalyst option. This listing also includes the ecobee by Generac Smart Thermostat, which is designed to integrate with Generac home standby generators for in-home energy monitoring and enhanced backup capabilities. Because this unit does not have a catalyst, it is not available for purchase in California or Massachusetts based on the supplied product note. With Quiet-Test mode, cellular connectivity, TruePower technology, and corrosion-resistant construction, this generator supports standby power planning when properly sized and professionally installed.

48kW Backup Power for 120/240V 1-Phase Applications

The XG04845ANAX is built for standby generator projects where 48kW output, 120/240V 1-phase service, and fuel flexibility are key requirements. Final load sizing, fuel setup, voltage requirements, and site conditions should be reviewed by a qualified installer before purchase or installation.

ecobee by Generac Smart Thermostat Integration

The included ecobee by Generac Smart Thermostat is designed to work with Generac home standby generators for in-home energy monitoring and enhanced backup capability. This adds useful visibility for buyers who want a more connected standby power setup.

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 Mode, TruePower Technology, and Corrosion Resistance

Quiet-Test mode runs a lower-speed five-minute self-test that can be programmed weekly, biweekly, or monthly. 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 XG04845ANAX is designed for permanent standby generator applications where 48kW output, 120/240V 1-phase service, and no-catalyst configuration are part of the project requirements. The included ecobee by Generac Smart Thermostat adds connected energy monitoring support for a more informed backup power setup.

With Quiet-Test mode, cellular connectivity, TruePower technology, 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.
