What a Whole-Home Standby Generator Is - A Plain-English Guide
Last verified: September 2026
Everything you actually need to understand a whole-home standby generator — what it is, how it switches your home over automatically, and what it takes to put one in. Rather talk it through? My number is (330) 200-8042.
Standby Generators, at a Glance
A whole-home standby generator lives outside, watches your power, and switches your home over to its own power automatically when the utility fails — no cords, no gasoline, no going outside in the storm. This guide explains what it is, how it works with an automatic transfer switch, how it differs from a portable, and what the install involves. There's a printable 29-page version up top.
Common Questions
1 What is a whole-home standby generator?
It's a generator that's permanently installed outside your home on a pad, wired into your electrical system through an automatic transfer switch, and connected to a permanent fuel supply — natural gas or propane. When the power fails, it starts and powers your home on its own.
2 How is it different from a portable generator?
A portable is stored, wheeled out, started, and refueled by hand every time. A standby is already outside, already wired in, and already fueled — it starts itself and switches your home over automatically, whether you're home or not. It costs more but asks nothing of you.
3 Does it turn on automatically?
Yes. An automatic transfer switch senses the outage, starts the generator, and switches your home from the grid to generator power — usually within seconds — then switches back and shuts down when the utility returns.
4 What does it run on?
Natural gas from the utility, or propane from a tank on your property. Natural gas usually keeps flowing during outages; propane stores for years but the tank is finite, so tank size matters for long outages.
5 Can I install one myself?
No. The electrical and gas connections require a licensed electrician, a licensed gas pro, and a permit — and doing it yourself isn't safe or legal and can void the warranty. It's a professional install, start to finish.
6 Do I really need one, or is a portable enough?
It depends on your outages, whether you're on a well, medical needs, and how much a portable's hands-on routine suits you. Frequent or long outages, well water, and travel all point toward a standby. Our standby-versus-portable guide compares them honestly.
Would You Rather I Just Help?
Understanding a standby generator before you spend is one of my favorite things to help with — I don't sell them, so it's just honest advice. I'll look at your home and your must-run list and help you decide if a standby is right, then line up licensed pros I trust. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
