OUR GENERATORS

TOP CERTIFIED Cummins Dealer in Texas

All communities require a stable power source. Unfortunately, outages can happen anytime, so San Antonio residents and business owners need something to jumpstart their operations. Generators are the most reliable option, and Cummins is a renowned brand. They provide a wide array of devices for all applications to ensure the owner receives energy in any circumstance.

Cummins power systems include gas and diesel-powered generators (15-3750 kVA), diesel engines, alternators, and battery storage units. The company manufactures all components of its generators, offering an integrated approach that guarantees a well-coordinated device. Regardless of the challenge, Cummins helps ensure resilient operation at any site through design expertise, first-class equipment, and excellent customer service.

Cummins Home Standby Generators

One of the most common types of generators is a standby unit. These backup power solutions supply a business with power during an outage. Typically, they’re stationary and have a concrete pad that provides a solid foundation outside the facility. Most impressively, these systems provide tremendous power during extended outages. But unlike continuous or prime models, they’re only used during blackouts or inclement weather.

Another quality of standby generators is that they provide power automatically, so the owner doesn’t need to be present during blackouts. For instance, if an owner is on vacation when an outage occurs, the standby system ensures the sump pump and other appliances run without compromising home security. Furthermore, most models can supply the entire home with energy because they operate on unlimited settings.

Cummins Portable Generators

Portable generators are diesel or gas-powered devices that provide temporary energy. They feature an engine that turns a turbine to create a certain amount of usable electricity, depending on the system’s wattage. Users can supply their tools or appliances directly from portable generators by plugging them into sockets. Alternatively, these systems can be wired into the home’s sub-panel to ensure several machines remain operational during outages.

Portable generators are perfect for commercial applications. For example, construction teams often use them to power their lights and tools at remote sites. Likewise, sports officials can bring them in for night play or operate electronic timers or scoreboards. Residents also use these systems during blackouts to keep their essential appliances running. In most cases, they provide enough energy to keep refrigerators, TVs, lights, and freezers working for an extended period.
