Looking for a top of the line home generator? We’ve been in the prepping game for a long time so we know the ins and outs of handling basic survival needs like what to eat, drink, and so on. After getting those squared away you’ll want to think about getting a home generator. It can be a complex task but we’ve done the research for you, compiling reviews from expert tradespeople in our research.

What’s the price of a generator for your whole house?

We’ve put together a full guide to help you figure out how to choose a home generator that will be right for you, let’s start with cost.

Including the price of installation, the full cost of getting your new generator will be between $500 to $3000. Smaller portable units do not require professional installation and will save you money.  

Next, we will describe the specifics of how much a generator will run you based on your needs. 

What is the best home generator size for my house?

To figure out what you need, begin by asking yourself how much wattage is needed: 

Where is your home’s water coming from?

Pumping water from a well requires 3800 watts or more for a 230+ volt generator.

What type of heating system do you have?

With systems using gas or forced oil for power, only a small generator is needed to produce at least 2500 watts. Larger furnace systems need more power

15,000 watts is the baseline for electric heat, so even the best portable generator for home use won’t be enough.

What type of system powers your hot water set up?

Like the systems we previously described, oil or gas systems use the least energy: around 2500 watts.

More energy, 4500 watts at minimum, will be needed for electric heat.

For houses that use municipal water and a small heating system, 3000-5000 watts will most likely be enough. Water from wells and large heaters take much more energy, 5000-7000 watts.


Lay Out Your Home’s Electric System

Once you figure out how you’re going to use your generator, you’ll then need to take a look around your home. Locate all of your power switches and wall outlets, and trip the service panel switches to discern what matches to which locations in your home.

What way should I go about this? It’s simple if you get help from a friend. Have your friend wait by the service panel tripping different switches then you will go around your home to see what switch turns off what. Using a phone or radio to communicate can be a big help. Be sure to record all of the information and you’ll be all set.

Figuring out Wattage for Your Home Generator

Determining the size of the home generator you should purchase means you need to add up how much wattage you will use.

It can be tricky, though it’s not as difficult as it may seem. You simply need to survey your home to discern what devices need power and then come up with the sum of their required wattage.

Typically you will find that your devices display its wattage somewhere like a label, but if you can’t seem to find one then you might find it listed in a manual, or by searching online.

We hope to give you safe estimates to work with, but don’t forget:

Appliances may use a range of energy, greater or less than what we’ve described.

When a product turns on it consumes a higher level of energy. Then it was dropped afterward while being used. An automatic home generator will help save unnecessary power waste with this.


How Big Should My Home Generator Be?

After you determine the approximate wattage needs for your home’s devices to use in a crisis you can figure out how big of a generator is needed. If you’re looking only for a  backup home generator then a smaller size should work. 

Little: Typically puts out roughly 2000-6000 watts. “Inverter generators” are the name for portable ones often used for camping. The more powerful the more they will cost.

Medium: Puts out 1500-5000 watts. Ideal when supplying just a few essential appliances.

Big: Puts out 6500-8000 watts. It can supply power for multiple rooms.

Oversize: Puts out 15000-20000 watts. It can supply a whole house. 

Some devices just require too much energy to safely keep running with a generator. You might want to consider switching to more energy-efficient appliances when thinking about the best power generator for home use.


Types of Home Generators: Solar lights or gas-powered?

When it comes to solar there aren’t many options available, but finding the solar-powered generator for home use can be done. You will need to pay more and end up with lower wattage but it can save you money long term. 

A gas generator for home is a reliable choice, most portable generators run on gas and they can output a low to the medium flow of energy. When thinking about the fuel you want to choose based on what is easily available, so you may want to think about a home diesel generator instead of gas.
