Cummins Diesel Generators

Whether you’re safeguarding a family home or keeping your business operations running smoothly, Cummins diesel generators deliver reliable backup power exactly when you need it. From quiet, efficient residential units to high-performance commercial diesel generators, Cummins offers scalable solutions built for any environment. Whether it’s a storm, a substation invader, or a homeland security incident, it is a relief to know that your power will kick on within seconds, barely enough time to reset your clocks.

For homeowners, a diesel standby home generator provides peace of mind during power outages—automatically restoring electricity within seconds. These stationary systems are connected directly to your electrical panel and can supply 100% of your home’s energy needs, unlike portable models that cover only the basics. With durable steel tanks ranging from 50 to 100 gallons, Cummins diesel generators can power your household for nearly two days without the need for frequent refueling.

Businesses can count on Cummins’ commercial generators to protect critical infrastructure, maintain productivity, and support customer satisfaction even during extended outages. Designed for long-term durability and high-load performance, these systems are ideal for retail, healthcare, manufacturing, and other commercial applications.

All Cummins units are enclosed, grounded, and protected against theft and weather exposure. They’re installed as permanent fixtures and may require permits prior to setup—but that’s where we come in. We offer generator startup and commissioning in Colorado to make sure you’re securely connected and valid for warranty protection. Our certified team of experts can also help you choose the best from all Cummins generators for sale, whether you’re powering a single-family home, a large estate, or a commercial facility.
