Home Standby Generators

For homeowners interested in permanent backup power generators to automatically power their homes during outages, there’s no better option than Generac’s best-selling models.

Generac is the most recognized name in home standby generators, and for good reason. As the brand that essentially created the residential standby generator category, Generac builds home standby generators specifically for one job: keeping your home powered automatically when the grid goes down. No extension cords, no manual startup, no interruption to your daily routine.

This is the Generac home standby generator, the heart of your backup power system. Permanently installed outside your home, it runs on natural gas or liquid propane and powers on automatically within seconds of an outage, no manual startup required.

The automatic transfer switch is installed at your home's electrical panel and acts as the brain of the system. It continuously monitors your utility power and signals the generator to start the moment an outage is detected. When utility power is restored, it transfers control back and shuts the generator down.

The generator sits on a pre-poured concrete pad, keeping the unit level, stable, and properly elevated off the ground. The pad is typically installed as part of the overall generator installation process and must meet local code requirements for size and placement.

Always On, Always Ready

Generac home standby generators are permanently installed outside your home and wired directly into your electrical system through an automatic transfer switch. The moment utility power is lost, the transfer switch detects the outage and the generator powers on within seconds, restoring electricity to your home whether you’re there or not. When utility power returns, the system transfers back and the generator powers down on its own.

Runs on the Fuel You Already Have

Generac standby generators are designed to run on natural gas or liquid propane, connecting directly to your existing fuel supply. That means no fuel storage, no trips to the gas station, and no risk of running out of power mid-outage.

Whole Home or Essential Circuits

Generac offers a wide range of output sizes, from units designed to keep your critical circuits running to larger systems capable of powering your entire house simultaneously. Whether you need backup for your furnace, sump pump, and refrigerator or full coverage for a larger home, there’s a Generac home standby generator sized for the job.

Quiet Enough to Be a Good Neighbor

Despite their output, Generac home standby generators operate at sound levels comparable to a central air conditioning unit, around 65 to 67 decibels depending on the model. Powerful without being disruptive.

Monitor From Anywhere

Many Generac models include built-in Wi-Fi connectivity and are compatible with the Mobile Link app, which lets you check your generator’s operating status, maintenance schedule, and alerts from your phone no matter where you are.

Professional Installation Required

Because home standby generators connect directly to your electrical panel and fuel line, installation must be handled by a Master Electrician familiar with generator hookups and local code requirements. Permits are typically required, and proper installation is essential for both safety and warranty coverage.
