Generac Diesel Standby Generators

The Industry's Most Comprehensive Line.

Diesel-fueled generators are the workhorses of the industry. They can be an efficient choice for high kW applications, as well as for facilities where code requirements (NEC 700 and NFPA 110) call for on-site fuel storage, like hospitals and 911 call centers. They can also provide backup power in remote areas where businesses do not have access to the natural gas supply.


To provide the best possible diesel-fueled solutions, Generac specifies diesel engines proven in real-world applications under adverse conditions. They are designed for:

  • Easy maintenance
  • Extreme endurance
  • Dirty fuel tolerance

Diesel engines also provide the response, power, and longevity required for many applications. They are also EPA-compliant from the Generac factory providing you with a single stop for all your generator support.
