How Big of a Backup Generator Do I Need?

The size of your generator is going to be dependent on your needs. If you want your house to be fully powered during an outage a 16Kw generator or larger should provide enough power to keep your house running. But if you need just the necessities or have specific medical needs you can use a 7Kw generator to operate a combination of a sump pump, refrigerator, garage doors, and some other dedicated outlets or devices.
