What is a Backup Generator?

A backup generator is permanently installed outdoors, much like an air-conditioning unit is. The generator operates on your home's existing fuel source - whether that's natural gas or liquid propane (LP). Sun Energy's standby power system includes the generator, automatic transfer switch, battery charger and distribution panel. The transfer switch is the brain of your backup power system. It continually monitors the utility power for an interruption. If utility power fails, the transfer switch automatically starts the generator, transfers the electrical loads and restores power to your home. When utility power resumes, the transfer switch reverses the process... again, automatically, whether you're home or away.
