Not sure what size you need? See our installation guide →The Generac 28kW standby generator fills the gap between the Guardian 26kW ceiling and the liquid-cooled Protector series — delivering 28kW on propane and 25kW on natural gas in a residential-sized cabinet that installs on a standard concrete pad. For large DFW homes where the 26kW would be stretched thin, the 28kW provides the headroom without the site-prep requirements of a commercial-class unit.
This model runs the same G-Force 1000 engine as the 22kW through 26kW Guardian units, and ships as a complete system with a 200-amp automatic transfer switch included — built-in whole-home surge protection comes bundled with it, a $300 value on its own. It also introduces Generac's Power Zone 200 Controller with cellular Mobile Link connectivity. Where the older Evolution-controlled Guardian models connect via WiFi, the Power Zone 200 uses cellular — meaning remote monitoring and status updates remain active even if your home's internet service is out during an outage. If you're not home when the power goes out, you'll know the generator is running before your WiFi router does.
True Power™ technology keeps total harmonic distortion below 5 percent for clean, stable power to inverter-driven HVAC systems and sensitive electronics. Quiet-Test™ weekly self-exercise mode verifies unit readiness at low load without the noise and fuel consumption of a full-load test.
HomeSafe installs and services the Generac 28kW across DFW — Fort Worth, Southlake, Keller, Flower Mound, Frisco, Plano, and surrounding communities. As a Generac PowerPro Elite+ dealer, we stock most parts locally and provide priority service support.
Note on fuel output: At 28kW on liquid propane and 25kW on natural gas, the 28kW has the widest LP/NG output gap in the residential generator line. Homes on a natural gas line needing closer to 28kW of output should confirm whether natural gas line pressure and volume can support peak load demand — this is part of the site assessment HomeSafe performs before installation.
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.
