What is a backup generator? [10 Best Generators for Properties]

A backup generator is an appliance that provides power during an electricity outage. You can choose between a portable generator or a whole-house generator. Portable generators run on gasoline while whole-house generators operate on natural gas or propane. Solar-powered backup generators are now available as well. Different generator models will have varying capacities and costs. Regardless of the type of generator you purchase, you’ll need a compatible transfer switch.
