Not sure what size you need? See our installation guide →The Generac 48kW XG Protector Series is the largest single-phase liquid-cooled standby generator Generac offers for residential-voltage service — designed for large DFW estates and light commercial properties where whole-facility coverage at 48kW is the baseline, not the stretch goal.
The 48kW Protector uses the same proven 4.5L liquid-cooled four-cylinder engine and compact enclosure as the 32kW and 40kW Protector models, sharing the same 83.4" × 34" × 45.2" footprint. Liquid cooling sustains rated output regardless of ambient temperature — no thermal derating during a July heat wave. Single-side maintenance access simplifies service scheduling and reduces the pad clearance required on one side of the installation.
Generac now bundles the 48kW Protector with the ecobee by Generac Smart Thermostat — connecting the generator to your home's HVAC management. During an outage, the thermostat can work in coordination with the generator's monitoring system to manage cooling loads intelligently, which matters when the generator is running extended cycles during a multi-day DFW outage.
Remote monitoring uses the 410 Controller with Mobile Link, and TruePower™ technology keeps total harmonic distortion below 5 percent for clean power to sensitive electronics and modern inverter-driven HVAC equipment.
HomeSafe installs and services the Generac 48kW Protector across DFW for large residential estates and light commercial properties. These installations require a reinforced pad, specialized lifting equipment, and coordinated fuel and electrical work — HomeSafe manages all of it.
We assess your electrical panel, confirm gas line access, and identify the best pad location. Takes 30–45 minutes. No charge, no obligation.
You receive a single all-in price — unit, transfer switch, concrete pad, gas line, electrical, and permits. No surprise add-ons after you sign.
Most installs complete in one day. We commission the unit, walk you through the controls, and your home is protected before we leave.
A whole-home generator is one of the most valuable upgrades you can make — and financing options may be available to help spread the cost. Get in touch and our team will walk you through what’s possible before you commit to anything.
