Cummins Quiet Connect 20kW Home Standby Generator | RS20A

Cummins RS20A

Cummins Quiet Connect 20kW Home Standby Generator supplies your entire home during an outage. Requires a Cummins Onan Automatic Transfer Switch (sold separately.)

The Cummins RS20A home standby generator connects permanently to your house through an automatic transfer switch and the natural gas or propane supply. It monitors the power company distribution lines 24/7, then automatically starts and runs when it detects an outage and continues to run until the utility restores power.

Cummins RS20A Home Standby Generator

Cummins RA Series Automatic Transfer Switches (sold separately) have a NEMA 3R rating for indoor and outdoor use. They install between the utility meter and a typical 100-amp or 200-amp main circuit breaker panel. Both Service Rated and Non-Service Rated switches are available. The generator controller monitors the utility supply and automatically starts the generator within seconds after the outage occurs. After the generator starts, it signals the transfer switch to supply the home with power from the generator.

Powerful motor starting capability allows the Cummins RS20A to start a 5-ton air conditioner while operating a full household load and supply clean power to sensitive electronics at the same time. From a no-load condition to accepting a normal household load, the voltage varies by no more than 1.25 percent. Under steady-state conditions, the RS20A maintains voltage within 1.25 percent and frequency never varies more than 1.25 percent. Clean, worry free power you can count on.

The Cummins Quiet Connect 20kW with Intelligent Load Management (**kit sold separately) learns and remembers the power requirements of 240-volt loads like air conditioners. Load management allows a smaller, more fuel-efficient generator to manage up to four central air conditioners or other heavy loads. The A051C329 Cummins Load Management Kit controls two appliances like an air conditioner or water water. Two kits can control four loads.

Monitor and control the Cummins RS20A from almost anywhere. Advanced Remote Access (no cost) uses the highway safety and monitoring network for vehicles and equipment. Check generator status, program exercise periods, even manually start and stop the generator using the Cloud Connect Smartphone App on phones, tablets, or computers. Send performance data directly to your authorized dealer for worry-free maintenance.

A compact, efficient design packs the Cummins RS20A Quiet Connect home standby generator into a 34 x 36 x 27-inch enclosure. The generator meets NFPA 37 code for installation just 18-inches from the home. A sleek and attractive cabinet blends into the landscaping.

Patented sound technology and an advanced housing design with a corrosion resistant aluminum exterior and galvanized steel interior reduces noise and vibration. Sound levels of just 65dBA make Cummins Quiet Connect 20kW one of the quietest in its class.

The Cummins RS20A Home Standby Generator comes equipped for operation down to zero degrees out of the box. Cold weather accessories extend the operating temperature well below zero for reliable starts across the northern continental United States.

A patented “Crank-Only” mode reduces wear and tear during the exercise cycle. The engine cranks without starting while the controller performs diagnostics. The RS20A generator gets the exercise it needs, while the controller ensures that the generator is operating correctly. This eco-friendly feature saves fuel and produces less noise than operating the generator for 5 to 20 minutes every week.

A Cummins QSJ999G Engine powers the RS20A home standby generator. Cummins, the world-class leader in diesel and natural gas engines, designed and built the propane or natural gas engine. The installer selects the fuel-type during installation.
