A whole-home generator, also called a standby generator, is the best way to ensure that you have consistent, automatic power in the event of an outage. Whole-home generators are permanently installed outside your home by a professional contractor. When the main power goes off, they will automatically kick on to restore your power within seconds. A standby generator can power your whole house for an extended period of time, which prepares you for any storm or disaster that may interrupt your main power supply.
The decision to purchase a whole-home generator is an easy one, but choosing which one to buy…? Well, that’s why you’re here! Read on to learn about the best brands and generators currently on the market.

We’ve compiled our top 5 brands for whole-home generators. We’re proud to report that they are all American brands, meaning that spare parts and service will cost you less than foreign models.
