How To Determine What Size Generac Generator You Need

Okay, friends, let's talk power! But not the kind that makes you a superhero (although, having backup power is pretty super). We're talking about generators, specifically Generac generators. Why Generac? Well, they're a trusted brand, and honestly, nobody wants their lights flickering during a zombie apocalypse... or, you know, a slightly less dramatic power outage.
Figuring out what size generator you need might seem intimidating, like advanced calculus or folding a fitted sheet. But trust me, it's way simpler than either of those! It's about ensuring you have enough juice to keep the essentials humming along when the grid decides to take a vacation. And who doesn’t love a good backup plan?
Step 1: Inventory Time! (The Fun Kind)
First things first, you need to make a list. Not a grocery list (though, snacks are always a good idea), but a list of all the electrical appliances you absolutely need to run during a power outage. Think of it as your survival kit, electricity edition. What's non-negotiable?
Must Read
We’re talking:
- Your refrigerator (nobody wants spoiled food, right?)
- Your furnace or air conditioner (depending on the season, a lifesaver!)
- A few lights (so you're not bumping into furniture in the dark)
- Your sump pump (if you have one – a flooded basement is definitely not fun)
- Maybe your TV or internet router (gotta stay connected to the world, and Netflix, obviously)
Be realistic! Do you really need to power your entire home theater system? Or can you survive a few hours without it? Prioritize the necessities, and you'll save yourself some money (and generator size).
Step 2: Watt's Up? (Understanding Electrical Power)
Okay, here comes the slightly technical part, but don't worry, I'll keep it painless. Every appliance has a wattage rating – it tells you how much power it consumes. This is usually found on a sticker on the appliance itself. Look for "Watts" or just "W."

Here's where it gets a tiny bit tricky: Some appliances, like refrigerators and air conditioners, require extra power to start up. This is called "starting wattage" or "surge wattage," and it's typically higher than the "running wattage." You must account for this!
If you can't find the starting wattage, a good rule of thumb is to multiply the running wattage by 3 for motors (like refrigerators and air conditioners). Better to overestimate than underestimate!
Step 3: The Math (It's Easier Than You Think!)
Now for the grand finale: adding it all up! Take your list of appliances, note their running wattage and starting wattage, and do some simple addition. Don’t worry, you can totally use a calculator (or your phone!).

First, add up the running wattage of all the appliances you want to run simultaneously. This gives you your total running wattage.
Second, identify the appliance with the highest starting wattage. You only need to add this one starting wattage to your total running wattage.
So, the formula looks like this:

Total Generator Size Needed = Total Running Wattage + Highest Starting Wattage
Let's say your total running wattage is 5000 watts, and your air conditioner has a starting wattage of 3000 watts. Then you'll need a generator that can handle at least 8000 watts. Easy peasy!
Step 4: Shop Around! (And Maybe Treat Yourself)
Now that you know your wattage needs, it's time to shop for a Generac generator! Look for models that meet or exceed your calculated wattage. It's always a good idea to have a little extra headroom – that way, you can add a few extra lights or charge your phone without worrying about overloading the generator. Think of it as having a little extra elbow room on an airplane – always a good thing!

Consider the type of generator too. Are you looking for a portable generator for emergencies, or a whole-house standby generator that automatically kicks in when the power goes out? The choice is yours!
Bonus Tip: Consult the Pros!
If you're still feeling unsure, don't hesitate to consult with a qualified electrician or a Generac dealer. They can help you assess your specific needs and recommend the perfect generator for your home.
Remember: This process is about empowerment! It's about taking control of your power supply and ensuring your comfort and safety during an outage. And hey, who knows? Maybe you'll even become the neighborhood hero, the one with the generator that keeps the lights on when everyone else is fumbling around in the dark.
So, go forth, calculate, and conquer! The world of backup power awaits. The knowledge is empowering, and the peace of mind it brings is priceless. Now that you know the basics, you're well on your way to selecting the perfect Generac generator and ensuring you're never left in the dark again. Start researching, explore your options, and get ready to embrace the freedom of having your own reliable power source. You got this!
