How Standby Generators Work (and Why They’re Better Than Portable Ones)

The Smart Backup Power Solution for Your Home

At McCay Southern Generators, we talk to a lot of homeowners who wonder: “Why should I invest in a standby generator when I could just grab a portable one from the store?” It’s a great question—and one we’re happy to answer.

Let’s walk through exactly how a Generac home standby generator works, and why it’s a better long-term solution than a portable generator.

What Is a Standby Generator?

A standby generator is a permanent backup power system installed outside your home—much like an HVAC unit. It connects directly to your home’s electrical panel and kicks on automatically within seconds of a power outage. No cords, no fuss, no scrambling.

It’s also connected to a fuel source like natural gas or liquid propane, so there’s no need to keep spare gas cans on hand.

How It Works (In Simple Terms)

1. Outage DetectedThe generator’s automatic transfer switch detects a power failure from the grid.

2. Power Restored in SecondsWithin moments, the generator starts up and begins delivering power to your home.

3. Automatic ShutoffOnce grid power returns, the system shuts itself down and switches you back to utility power—seamlessly.

Portable vs. Standby: What’s the Real Difference?

Why a Standby Generator is Worth the Investment

With a standby system, you’re not just buying a generator—you’re buying:

• Peace of mind during storms and outages

• Reliable power to keep your family comfortable and safe

• Protection for sensitive electronics, refrigerated food, and medical equipment

And most importantly, you're removing the stress and guesswork when the lights go out.
