10 Best Home Electrical Generators We've Tested 2025: Top Rated

The best generator to run a house depends on various factors, including the size of your home, the number and type of appliances you want to power, your budget, and your specific power needs. Standby generators are often considered the best option for running a house because they provide seamless backup power during outages. Brands like Generac, Kohler, Briggs & Stratton, and Cummins offer reliable standby generators in various sizes and fuel types to match different home requirements.

How big of a generator do I need to run a house?

Determining the size of the generator needed to run a house involves calculating the total wattage requirements of all the appliances and systems you want to power simultaneously during an outage. This includes considering the starting wattage of appliances, which can be higher than their running wattage. While the size of the generator needed varies depending on individual circumstances, standby generators typically range from 8kW to 22kW for residential use, with larger homes requiring higher capacity generators.

Is a 22kW generator big enough for a house?

A 22kW generator can often provide sufficient power for many average-sized homes during an outage. However, whether it's big enough for your house depends on factors such as the size of your home, the number and type of appliances you need to power, and any additional power requirements you may have. It's crucial to assess your specific needs accurately and consult with professionals to determine if a 22kW generator is adequate for your home.

Is it worth getting a whole house generator?

Whether it's worth getting a whole house generator depends on your individual circumstances and priorities. Whole house generators offer several benefits, including automatic operation, seamless backup power, and the ability to maintain comfort and safety during extended outages. They can also increase the resale value of your home. However, whole house generators can be a significant investment, so it's essential to consider factors such as your budget, the frequency of power outages in your area, and your reliance on electrical devices and appliances when deciding if it's worth it for you.
