Description

The Cummins QuietConnect™ series of home standby generators, including the RS20A (MPN A071Z397), provides reliable and seamless backup power for homes. These generators are designed for ultra-quiet operation, producing a best-in-class 65dB or lower noise level from 23 feet away, comparable to a normal conversation. Key features include remote monitoring and control capabilities via a mobile app, intelligent load management to prioritize essential appliances and manage power between multiple air conditioning units, and all-weather reliability, with starting capabilities down to 0°F and a durable aluminum enclosure with galvanized steel interior built to withstand winds up to 180 mph. The compact design allows for installation as close as 24 inches from the home. The generator can run on either natural gas or liquid propane.
