Cummins: The Pinnacle of Integrated Power Systems

A global power leader founded on diesel engine innovation, Cummins is defined by its vertically integrated approach to manufacturing. By designing and building every major component of its power systems—from the engine and alternator to the controls and aftertreatment—Cummins delivers a fully harmonized solution engineered for optimal performance and reliability. This “Power of One™” philosophy makes them a preferred partner for complex, mission-critical applications like healthcare and data centers.

Cummins Generator

Profile

Founded in 1919 in Columbus, Indiana, by mechanic Clessie Cummins and banker William G. Irwin, Cummins Inc. was built on the pioneering development of the diesel engine. The company’s reputation for quality and reliability was forged in the early days of the American automotive industry and solidified during the post-World War II road-building boom, where its famous N series engines powered more than half of the heavy-duty truck market.

The Cummins Generator Portfolio

Every critical piece is designed to work together. That is the heart of the Cummins approach.

  • Product lines: Diesel, natural gas, and HVO-ready generators. Stamford® and AvK® alternators. Automatic transfer switches. PowerCommand® controls.
  • Power range: From small commercial needs to high-horsepower units for the largest facilities.
  • Fuel options: High-efficiency diesel and natural gas with broad support for renewable diesel (HVO) across the lineup.

Why Cummins

  • The Power of One™: Engine, alternator, controls, and aftertreatment come from the same company. Systems are matched from day one and supported by a single partner.
  • Fuel efficiency and emissions leadership: Engine know-how translates into lower operating costs and confidence with current and future regulations.
  • Mission-critical expertise: Data centers, hospitals, and water infrastructure rely on Cummins for ratings, packaging, and deployment models built for zero-excuses uptime.
  • Digital oversight: PowerCommand® plus cloud connectivity enables real-time monitoring, protection, and streamlined paralleling.

    What is Cummins PowerCommand and why does it matter?

    PowerCommand is Cummins’ control platform for generator protection, monitoring, and paralleling. It simplifies integration and gives you one controls ecosystem from the same manufacturer.

    How do I choose between Cummins QSK high-horsepower and Centum series units?

    QSK serves heavy industrial and large standby applications with proven durability. Centum emphasizes high efficiency and packaged performance for modern facilities. We pair the right line with your load and runtime needs.

    Are Cummins generators compatible with HVO renewable diesel?

    Many newer Cummins diesel models are HVO-capable. We verify compatibility by model and can help with fuel commissioning and documentation.

    What is the typical lifespan of a used Cummins diesel generator?

    With proper maintenance, Cummins diesel generators are known to run for tens of thousands of hours. Many standby units have low hours and a lot of life left. Our inspection helps estimate remaining life.

    Do used Cummins generators come with a warranty?

    Used units do not carry a new manufacturer warranty, but Generator Source offers warranty options or guarantees on select units. Ask about coverage for the specific generator you are considering.

    Can Generator Source assist with installation and ongoing maintenance for a used Cummins generator?

    Yes. We can handle installation and connect you with our service teams for maintenance, parts, and technical support. Service locations include Austin, TX, Brighton, CO, Jacksonville, FL, and Pensacola, FL.

    How do I know the condition of a used Cummins generator?

    Every unit receives a comprehensive 31-point inspection, including load bank testing. We share reports, photos, and often videos so you have full transparency on condition and performance.

    Are replacement parts readily available for older Cummins generator models?

    Yes. Cummins’ global parts and service network is a major advantage. Parts for most Cummins engines and generator models are widely available, which supports long-term ownership.
