What to look for in top-rated home backup generators

1. Power Output

The amount of power the generator can produce is crucial. This should match or exceed the total wattage of the appliances and devices you plan on using during a power outage.

2. Fuel Type

Home backup generators typically run on gasoline, diesel, propane, or natural gas. Each type has its own pros and cons in terms of availability, cost, and environmental impact.

3. Noise Level

Generators can be noisy. Check the decibel level to ensure it won't cause too much disturbance, especially if you live in a residential area.

4. Automatic Transfer Switch

An automatic transfer switch (ATS) allows the generator to start up automatically when power is lost, and shut down when it's restored. This is particularly useful for maintaining power during unexpected outages.
