The QuietConnect™ air-cooled series is built for homeowners who want whole-house backup without the noise — a best-in-class 65 dB(A) or lower, about the volume of a normal conversation, in a compact 34 x 36 x 27 in footprint. It runs on natural gas or LP vapor, starts itself when utility power drops, and returns to standby when the grid comes back.
Features and benefits
- Quiet by design. Sound-insulated, weather-protective enclosure rated 65 dB(A) or lower.

- Intelligent load management. With a load management kit, the control cycles high-demand appliances on and off so the set carries the whole home without overloading.
- Remote monitoring and self-diagnostics. Cummins Connect Cloud™ app for iOS and Android, email notification, and fault detection with service info on the in-home display.
- Clean power, simple install. Electronic governor and less than 5% THD; molded polymer base means no concrete pad, and a flexible 12 in fuel line ships with the genset.
