7210 - 24/21kW Air-Cooled Standby Generator, Aluminum Enclosure, 200 SE ATS w/ HEMS (not CUL)


  • Generac 7210 is the latest addition to the Guardian Series home standby generator family. It runs on a Generac G-Force V-Twin overhead valve industrial engine with a maximum 3600 RPM. The 999cc engine has a “Spiny loc” cast iron sleeve for longer life.
  • G-Force design is more fuel efficient and runs cooler while consuming less oil. It is purpose-built for extended use.
  • The 120v/240v 60Hz automatic home generator runs on LP or natural gas. When grid power fails the ATS commands the engine of the generator to start functioning. Your home appliances will continue to run safely throughout the outage.
  • On natural gas, the generator produces 21kW and 24kW on LP. The model runs quietly with low emissions and provides clean power for sensitive electronics.
  • True Power Technology offers best-in-class utility-grade electrical power with less than 5% THD.
  • The 200-amp, indoor and outdoor rated NEMA 3R transfer switch with aluminum enclosure powers all circuits of the house. Choose to power a few circuits or all.
  • The variable speed technology allows the air-cooled gas engine to change its speed according to the changing load. Engine runs smoothly under no pressure from the load you add.
  • Smart, user-friendly controls make the model easy to use and maintain. Generac’s Evolution™ Controller features a multilingual display. You can check the battery status and track maintenance intervals in the language of choice.
  • You can also check the status of the unit any time of the day or night from anywhere in the world on cell phones, tablets, laptops, and PCs. Mobile Link ™ Remote Wireless Monitoring allows you to get connected for real-time updates and get in touch with the service dealer for prompt service when required.
  • This automatic standby generator is backed by a 5-year limited consumer warranty.
