How Many Watts Is A Whole House Generator

Okay, let's talk generators. Whole house generators, to be exact. The unsung heroes that keep the lights on when Mother Nature throws a tantrum. But how many watts do you really need?

The Wattage Wonderland

Figuring out generator wattage can feel like navigating a confusing theme park. There are so many numbers! And everyone seems to have a different opinion.

The "Official" Answer (which I mostly ignore)

The "experts" will tell you to meticulously calculate the wattage of every single appliance. Then, add them all up. Sounds fun, right? (Spoiler alert: it isn't.)

They'll suggest getting a professional electrician. Which, honestly, isn't bad advice. But, where's the adventure in that?

My Unpopular Opinion: Common Sense Wins

Here's my hot take: most people way overestimate what they need. We're talking serious overkill. A 20kW generator? Do you really need to run a welding shop during a blackout?

Let's be real. Are you going to be running your dishwasher, washing machine, and oven simultaneously during a power outage? Probably not.

The "Essentials Only" Approach

I'm a big fan of the "essentials only" approach. Think of it as minimalist living, but powered by a generator. What do you absolutely need?

Lights? Check. Refrigerator? Definitely. Maybe the TV to catch up on the news (or binge your favorite show). Essential electronics like charging your phone.

Forget the electric toothbrush charger. Ditch the hair dryer. You'll survive, I promise.

The Wattage Breakdown (Rough Estimates)

Let's get down to some (very rough) numbers. Keep in mind, these are just estimates. Your mileage may vary. Blah, blah, blah.

Refrigerator: 600-800 watts (starting wattage can be higher).

Lights (LED): 5-15 watts per bulb. LED are the only way to go!

TV: 100-200 watts (depending on size and type).

Laptop: 50-100 watts.

Cell Phone Charger: Practically nothing (5-10 watts). But essential for survival!

The Starting Wattage Trap

Here's a sneaky little trick the wattage calculators often overlook. Appliances with motors (like refrigerators and air conditioners) require more power to start than to run.

This is called "starting wattage." It's like needing a running start to climb a hill. The generator needs to handle these brief surges.

A refrigerator, for example, might only need 150-200 running watts. But starting it requires a surge of 600-800 watts. That initial burst matters.

Finding Your Generator Sweet Spot

So, how do you find the sweet spot? The Goldilocks wattage that's just right?

Consider Your Comfort Level

First, be honest with yourself. How comfortable are you with roughing it? Can you handle a few hours without the microwave?

If you need to run the entire house, including the jacuzzi, you'll need a bigger generator. If you're happy with the basics, you can get away with less.

The "Test Run" Approach

Here's a simple (and free!) method. During your next power outage, make a note of everything you actually use. Just the essentials. Write it down.

Then, use those numbers to estimate your wattage needs. It's a real-world test. No fancy calculators required.

My Recommendation (Grain of Salt Required)

For most average-sized homes (1500-2500 square feet), I think a 7500-watt generator is plenty. Seriously. It'll cover the essentials without breaking the bank.

Add a window AC, bump it up to a 10,000. Add a central AC and bump it up to 15,000 or higher. Depends on the size of your AC unit.

But, again, consider your lifestyle. And your tolerance for discomfort.

Generator Types: Portable vs. Standby

Now, let's briefly touch on generator types. There are two main contenders: portable and standby (whole house).

Portable Generators: The Budget-Friendly Option

Portable generators are cheaper. They can be moved around. But they require manual setup and refueling. This means more work when the power is out.

They typically run on gasoline or propane. Which you need to have on hand.

Standby Generators: The Set-It-and-Forget-It Option

Standby generators are permanently installed. They automatically kick on when the power goes out. Super convenient, but also more expensive. A whole house generator.

They usually run on natural gas or propane. Giving you a continuous fuel supply.

Installation Considerations

Whether you choose a portable or standby generator, installation is key. Improper installation can be dangerous. Carbon monoxide poisoning is no joke.

For portable generators, always operate them outdoors, away from windows and doors. Ventilation is crucial.

For standby generators, hire a qualified electrician and plumber. They'll ensure everything is installed safely and according to code. Don't cut corners here.

Maintenance Matters

Generators are like cars. They need regular maintenance to stay in top shape. Don't neglect them.

Change the oil. Clean the air filter. Check the spark plugs. Follow the manufacturer's recommendations. It's worth it.

A well-maintained generator will be there for you when you need it most. A neglected one will leave you in the dark.

The Bottom Line: Don't Overthink It

Choosing a generator can feel overwhelming. There are so many factors to consider. But don't overthink it.

Assess your essential needs. Choose a generator that meets those needs. And don't be afraid to downsize. You might be surprised at how little you actually need.

After all, a little discomfort is a small price to pay for peace of mind. Especially when the lights go out.

And remember, a generator is just one piece of the puzzle. Battery backups for your computer and other important electronics are also great to have.

Consider a UPS (Uninterruptible Power Supply) for your computers, modems, and routers. It'll provide you with enough power to properly shut down computers.

Or if you want, it will allow you to work a few more minutes while you wait for the generator to get going.

Good luck finding the right generator for your home! May your lights always shine bright (even during a power outage). And may your neighbors be jealous of your preparedness.

Because if you don't have a generator, you'll be going to your neighbor to charge your phone.

Always keep your gas tank for your generator as full as possible. Nothing worst than a generator that stops working during a power outage because it ran out of gas.

Have your generator be ready for you during an emergency.

So, to answer the question: how many watts is a whole house generator? It depends! But probably less than you think!
