Cummins standby generators
QuietConnect is Cummins' residential home-standby generator line—not a separate generator company. The range includes compact 13, 17 and 20 kW-class air-cooled systems plus larger residential/light-commercial models. This guide explains the model names, remote monitoring and ownership decisions before sending you to the exact manual or dealer.

What the Cummins terms actually mean
QuietConnect
Cummins' name for its residential standby-generator family. The name emphasizes sound-attenuated enclosures and residential use; the QuietConnect range still contains multiple model sizes with different parts and maintenance requirements.
Read the official explanation ↗RS13A / RS17A / RS20A
Cummins model-family codes for residential/light-commercial standby generators. The number roughly identifies the model's kW class, but do not decode parts, battery size or exact fuel output from the name alone—use the model spec sheet.
Read the official explanation ↗Cloud Connect
Cummins' current homeowner remote-monitoring app. It lets an owner monitor a supported home standby generator remotely rather than walking outside to check the controller.
Read the official explanation ↗Crank-only exercise
A Cummins exercise option on supported QuietConnect models that can crank the engine and run diagnostics without fully starting it. It is one of several configurable self-test modes, not a universal feature of every generator brand.

Five terms you should not have to decode
kW (kilowatts)
A measure of generator power. One kilowatt equals 1,000 watts. A bigger kW number means more electrical capacity, but it does not automatically mean the generator can run every appliance in every home.
ATS (automatic transfer switch)
The electrical switch that detects a utility outage, disconnects the home from the grid and connects it to generator power. When utility power returns, it switches the home back automatically.
Air-cooled vs. liquid-cooled
Two different ways the engine removes heat. Air-cooled units are common in smaller residential standby systems; liquid-cooled systems are generally used as capacity and engine size increase. Maintenance and installation rules differ.
Exercise / self-test cycle
A scheduled automatic test the generator performs when there is no outage. It is simply checking that the system can start and report faults; it has nothing to do with a workout program.
Load management
A control strategy that delays or prioritizes selected large appliances so they do not all demand power at the same time. It can sometimes let a smaller generator support more of the home without overloading.
What stands out
- Cummins publishes the QuietConnect residential family as sound-attenuated, with a manufacturer claim of 65 dB or lower for the series.
- The RS13A, RS17A and RS20A share a well-documented air-cooled family with model-specific spec sheets and cold-weather options.
- Cummins publishes a Cloud Connect monitoring path, automatic-transfer-switch guidance and homeowner sizing resources in one residential support ecosystem.
What to verify
- • Dealer and service availability is local; check the Cummins locator in your area before assuming a nearby residential service option.
- • Cummins' 13/17/20 kW models have different warranty treatment from larger 25–125 kW families according to the current homeowner FAQ.
- • Battery groups, cold-weather kits and maintenance parts must be matched to the exact RS model.
- • The current homeowner remote-monitoring name is Cloud Connect; older third-party references may use different Cummins/Onan terminology.
Model families in our research
These cards open current manufacturer information until we have enough verified depth to justify a dedicated model page of our own.
RS13A
13 kW-class QuietConnect residential/light-commercial model. Use the exact spec/manual before ordering a battery, heater or maintenance part.
View official model information ↗RS17A
17 kW-class air-cooled QuietConnect model in the same core residential family, but still requiring model-specific parts and maintenance lookup.
View official model information ↗RS20A
20 kW-class QuietConnect air-cooled model. Cummins publishes its own product/spec information rather than treating it as an interchangeable RS13A/RS17A variant.
View official model information ↗Larger QuietConnect RS models
The residential/light-commercial line extends well beyond 20 kW. Larger models move into different engines, batteries, warranties and service requirements.
