The Generac 22kW Standby Generator is a permanently installed, air-cooled home standby power solution designed to provide automatic backup electricity during utility outages. Connected to an existing natural gas or liquid propane fuel supply, this generator is rated for 120/240V single-phase operation and is commonly paired with a 200 amp automatic transfer switch for whole-home or large-load coverage. It is well suited for residential applications where maintaining power to critical systems such as HVAC, refrigeration, lighting, home offices, medical equipment, and connected devices is required. The system is engineered to start automatically when a power loss is detected and to run continuously until utility power is restored.
This 22kW Generac standby generator incorporates electronic fuel and ignition control to optimize fuel usage and support stable power output. Built-in cellular connectivity enables remote monitoring of generator status, performance, and maintenance alerts through the Mobile Link platform. Additional design features such as oil level sensing, improved cold-weather starting, and an enclosed aluminum cabinet with a sloped roof support reliable operation in a range of environmental conditions. Typical use cases include primary residences, large homes with central air conditioning, and properties requiring dependable backup power for extended outages.
