Things to Consider Before Buying Best Whole House Generators

Although you might know all about the different kind of generators available on the market, it’s still not enough to make the right decision. Whole house generators have certain features that you need to keep an eye on while purchasing. We have discussed these features in detail below.

  • Automatic Shutoff

The first thing you need to make sure of is if the whole house generator you want to buy comes with an automatic shutoff feature. This will ensure that the generator isn’t running on low fuel as it automatically turns off in that case.

On the other hand, this feature can also turn on the device by itself in terms of a power outage.

  • Type of Enclosure

You might already be aware of the fact that a whole house generator is usually placed outside your house. This means they would have to endure the damage caused by different environmental conditions over the years. Hence, it’s only wise to pick a generator that comes with a heavy duty steel frame.

A thicker enclosure will also reduce the amount of noise it gives off. It’s also ideal to choose a material that is resistant to rusting and corrosion.

  • Generator Capacity

Before you buy any whole house generator, you first need to consider the type of house you live in and the amount of power you need. It would be foolish to buy a model that generates more electricity than you need. Similarly, a low powered generator won’t do you any good if you own a large suburban home.

Smaller whole house generators come with a power capacity of 20kW to 50 kW. There are also some generator power calculators online that will help you determine which generator is most suitable for your household.

Final Verdict

We have finally reached the end of this guide on the best whole house generators. Make sure you go through all the different features of all the models we reviewed. That’s how you will be able to know which of the features appeal to you the most. However, you shouldn’t only base your decision on that.

Make sure you keep the key factors in mind when you are out purchasing a whole house generator. To get a better idea about which model to choose, you should also measure the square footage of your household. The number of electronic appliances in your house should also be taken under consideration.
