As the #1 selling home standby generator brand, Generac’s 7,500-Kilowatt Whole Home standby generator is the most affordable, automatic alternative to portable backup power. Features incorporate many of the qualities and reliability of the bestselling Guardian Series, while remaining the most affordable home standby generator available. Significantly quieter than a portable generator, it protects the home’s most essential circuits, like refrigerators, well pumps and select appliances, without having to manually set up during inclement weather, refuel, or run electrical cords.
