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.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e48kW Backup Power for 120\/240V 1-Phase Applications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe XG04845ANAX is built for standby generator projects where 48kW output, 120\/240V 1-phase service, and fuel flexibility are key requirements.
