Cummins RS20AE 20KW Quiet Connect Extreme Weather Generator

The all-new Cummins RS20AE is a 20kW emergency standby gas generator that will power your 5-ton air conditioner, security system, and all other home appliances when grid power fails. Storms, hurricanes, tornadoes, and wildfires bring down power lines and you need a reliable source of power to keep the day running as usual. This air-cooled model runs on LP and natural gas. During a power outage, run it for as long as it takes for grid power to get restored to the neighborhood. There is no need for refueling when you run it on natural gas.

Remote monitoring allows you to turn your unit on and off from any location using the Smartphone, tablets, laptops, and PCs. Control real-time operations and diagnostics or view status codes from near or far. The advanced voltage and frequency regulation protects all home appliances that have micro-chips. Total harmonic distortion is less than 5%, ideal for use with computers, laptops, cell phones, and tablets. The heavy-duty engine runs quietly at 65dBA. Safety features, low cost, remote monitoring, and high performance make this 20kW emergency standby gas generator an ideal choice for home, shop, and office. Cummins RS20AE is easy to operate and maintain. All Cummins products are made in the USA and are backed by warranties and nationwide dealer networks.
