Very quiet and reliable power

Ordered and installed 20KW with 200 amp panel in Michigan 11-2021. Shipping was fast and arrived damage free on time. This unit is very, very heavy. Do not short cut on the site prep. I used a concrete pad on top of pea gravel and it has not settled. The transfer panel is large and has to placed in a area that is accessible. The transfer panel is 200Amps and MUST be matched to a 200 amp service panel that wired in your building. When power goes out the switch over to generator power is very short time, just a few seconds after it started. This generator is so quiet. We don't know its running in the house. We have a 4 ton air conditioner, well, sewer, grinder pump, hot tub, two fridges, all the normal appliances, lights, gas heat, gas dryer. The highest load was 48% of capacity. This unit is set up for ethernet remote monitoring which can be viewed from an app on your phone. It has 183 hours of time on it now and has worked perfectly during power outages. I have both this model at our primary home and a Generac Guardian at a remote Michigan vacation home. Overall they both work well, but prefer the Cummins due to being quiet and switch over time. Would recommend.

Cummins QSJ999G Engine powers the RS20A home standby generator. Cummins, the world-class leader in diesel and natural gas engines, designed and built the propane or natural gas engine. The compact and sleek design allows you to safely install this generator just 18 inches from the home, and practically blends into the landscaping. This generator has a corrosion resistant aluminium casing with galvanized steel interior which redueds noice and vibration so sound levels are 65 dB(A) - one of the quietest in its class.

The cummins RS20A is prepared right out of the box for operation at temperatures down to zero degrees. Cold weather accessories can allow this generator to operate at temperatures far below zero degrees, which make a senesible addition to any home across the nothern united states.

This powerful motor allows the capability to start and run a 5-ton air conditioner while managing a full household load and allowing you to power sensitive electronics with less that 5% total harmonic distortion.

 

The RA Automatic Transfer Switch is integrated with the RS series genset. These products are Listed to UL 1008, the Standard for Transfer Switch Safety. The switch and generator set combination is specifically designed for a simplified, quicker installation.

The RA transfer switch monitors utility power 24 hours a day and 7 days a week. When utility power becomes unsatisfactory or fails; the generator set is signaled to start, then automatically transfers the load. When stable utility voltage returns, the transfer switch will automatically switch electrical load from the generator to the utility. No action is required by the home owner.
