Choosing the right home standby generator to suit your family's needs is an important decision and one of the best a homeowner can make. Home standby generators are low maintenance and kick on automatically when the power is lost. With larger capacities, they can do more than just keep the lights on. Whether you need a home backup generator to power your whole house or just a few rooms, you will have no problem selecting the home backup generator that’s right for you. Shop a vast selection of natural gas, propane (LP), and diesel home backup generators today.
