What to look for in top-rated standby generators

1. Power Capacity

The first thing to consider is the power capacity of the generator. It should be able to handle your home’s power needs, so calculate the total wattage of all appliances and systems you want to keep running during a power outage.

2. Fuel Type

Standby generators can run on various types of fuel like natural gas, propane, or diesel. The choice of fuel type will depend on availability and cost-effectiveness in your area.

3. Transfer Switch

A transfer switch is necessary for safe operation. Automatic transfer switches start the generator automatically during a power outage and shut it down when utility power returns.

4. Noise Level

Generators can be loud, so consider the noise level if it's located near living spaces. Some models come with sound-dampening technology.
