<h3>Cummins Onan: A Century of Reliable Power Generation</h3><p>Few names carry as much weight in the power generation world as <strong>Cummins Onan</strong>. The story begins in 1920 when D.W. (David) Onan founded the Onan Corporation in Minneapolis, Minnesota, pioneering small engine-driven generators at a time when reliable electricity was the leading technology of the era. Over the following decades, Onan built one of the most respected distributor and service networks in the industry, earning a reputation for durability that outlasted countless competitors.</p><p>In 1986, Onan Corporation became a fully owned subsidiary of Cummins Inc., one of the world's largest designers and manufacturers of diesel and alternative fuel engines. Rather than diluting the Onan legacy, Cummins amplified it — bringing global engineering resources, deeper parts availability, and a worldwide certified dealer network to back every unit sold. Today, the Onan name lives on as a dedicated generator product line within the unified Cummins brand, particularly in the RV, marine, and standby power markets.</p><h3>Purpose-Built Power for Every Application</h3><p>What sets Cummins Onan apart is the breadth of its application coverage. Whether you need a compact genset for a weekend RV trip, a robust marine unit for life on the water, or a commercial standby system to protect a business, there is an Onan-engineered solution for the job. The <a href="/7305-cummins-onan-generators-generator-2700">Generator</a> lineup spans from the popular QG series — the number-one RV generator brand in North America — all the way up to large commercial and marine sets exceeding 100 kW. Major motorhome and towable manufacturers factory-install Onan generators, a testament to the brand&apos;s reliability credentials.</p><p>Keeping these generators running at peak performance requires quality parts, and Cummins Onan delivers on that front too.
