Caterpillar: The Global Standard for Durability and Reliability
Legacy of Power: 100 Years of Building a Better World
The Caterpillar brand is built on a century-long foundation of engineering excellence and unparalleled durability. The company’s origins trace back to the 1925 merger of Holt Manufacturing and C. L. Best Tractor Co., two pioneers who revolutionized agriculture and construction with the invention of the track-type tractor.35 This heritage of building machines for the world’s toughest jobs is deeply embedded in the DNA of their power generation systems.Caterpillar’s journey into power generation began in earnest in 1931 with the production of its first diesel engine, the D9900.36 This innovation quickly established the company as a leader in diesel technology, and by 1937, it was the world’s largest producer of diesel engines.37 Throughout history, Cat® power has been trusted for monumental tasks, from helping to build the Hoover Dam to supporting Allied forces during World War II, cementing a global reputation for unwavering reliability.
Profile
Cat’s first diesel engine arrived in 1931. By the late 1930s the company was a leader in diesel technology. Over the decades Cat power supported landmark projects and critical missions, which is why the name still signals reliability to operators everywhere.
The CAT Generator Portfolio
Cat offers one of the broadest generator lineups in the market, built to perform across climates, regulations, and applications.
- Product lines: Diesel and natural gas generator sets, mobile units, Cat® Switchgear, ATS, and Battery Energy Storage Systems that can tie into microgrids.
- Power range: From small single-digit kVA models to multi-megawatt plant-scale systems. There is a precise fit for nearly any site.
- Fuel options: Diesel and natural gas are core strengths. Cat also supports renewable and emerging fuel pathways to help organizations meet sustainability goals.
Why CAT
- Global dealer network: Parts, service, and expertise are easy to reach. For remote projects or multi-site operators, this support often becomes the deciding factor.
- Built for harsh environments: Designs originate from construction and mining. Expect long life and steady performance when conditions get difficult.
- Low total cost of ownership: Efficient engines and straightforward maintenance keep life-cycle costs down. Strong resale values protect the investment.

Are Cat® generators compatible with Cat switchgear and ATS for a fully integrated system?
Yes. Cat gensets are designed to integrate with Cat switchgear and Cat Automatic Transfer Switches. We confirm model-level compatibility and provide one set of drawings so the whole system works as intended.
Can I monitor a Cat generator remotely with Cat Connect?
In most cases, yes. With the right hardware and a subscription, Cat Connect enables remote status, alarms, and basic analytics. We can quote hardware, setup, and onboarding.
How do I choose between Cat 3500 and C175 series for megawatt-class loads?
Both are proven for large standby and prime applications. The 3500 is a long-running workhorse with wide parts availability. The C175 delivers higher power density and is often selected for large critical sites. We help match the series to your load profile, footprint, and emissions requirements.
What is the typical lifespan of a used Caterpillar diesel generator?
With proper maintenance, Cat 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 Caterpillar 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 Caterpillar 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 Caterpillar 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 Caterpillar generator models?
Yes. Cat’s global parts and service network is a major advantage. Parts for most Cat engines and generator models are widely available, which supports long-term ownership.
