Home Standby Residential Generators
Comfort, security and convenience are things you can depend on with a Cummins Onan residential standby or portable generator … just in case the power goes out. It is easy to forget how much we depend on power. We use it for everyday essentials like heating, cooling, security, refrigeration, lights, cooking and bathing. With power outages occurring more and more frequently, it is good to be prepared. A Cummins Onan standby generator can give you peace of mind and the ability to live your busy life, uninterrupted.
Generally, a Cummins Onan residential home standby generator set offers many features not found on portable generator sets, such as a more sophisticated control system, a fully weather–protective enclosure, significantly quieter operation, and more capacity so you can power more conveniences. It goes on automatically when you need it and shuts down automatically once main power is restored. It is connected directly to a fuel system and your home's electrical system so you won’t have to fill a gas tank or manually transfer power from the utility to the home standby unit.
