This residential generator has enough power to keep you cool on a hot day same as it can generate heat to keep you warm and comfortable in case of an unexpected winter blizzard. Power outage is no longer an issue with CUMMINS RS20AC. Its engineering is there to prevent troubles related to power outage so you can keep enjoying life when the world around you is on standstill.

The RS20AC home standby generator is permanently connected to your home with the use of an automatic transfer switch. The CUMMINS RS20AC operates on the existing supply of natural gas (at 18kW) or LP gas (at 20kW) from your home (it is important to take into account the difference in power depending on the fuel used). The CUMMINS RS20AC operates non-stop during a power failure. The RS20AC monitors the power company distribution lines and switches on automatically in the moment it detects outage. The generator then runs uninterrupted until the utility power is restored.  

The RS20AC is designed to handle cold climates with temperatures bellow 0°F (-18°C) and colder if need be. The generator can easily manage up to 4 loads simultaneously while it continuously monitors how much power is required independently for each load. The CUMMINS RS20AC has powerful engine starting ability and can easily kick off and run a 5-ton air conditioner while operating a full household load providing clean power to sensitive electronics all at the same time.

In order to maintain it in perfect working conditions this superb home standby generator has a ‘Crank only’ mode. The CUMMINS RS20AC has an exercise mode of operation, which can be set to the time, date and frequency that suits you best. ‘Crank only’ exercise mode reduces engine wear, fuel costs and further reduces the sound of an already quiet generator.
