Generac QuietSource 22kW (Alum) NG/LP 240 3 Phase
Generac Power Systems

Generac makes it easy to configure a standby backup power system for your home or business needs. The 22kW liquid-cooled generator is capable of providing standby backup protection for large homes and commercial applications, designed specifically for high demand power generation needs.
Low speed, automotive style liquid-cooled engine runs at only 1800 rpm during a power outage for a substantially quieter generator, greater fuel efficiency, and longer engine and alternator life.
Super quiet, super efficient, patented Quiet-Test mode for a weekly test mode that’s quieter than other brands, consumes less fuel and helps make your Generac generator the most environmentally friendly on the market.
Standard aluminum, all-weather enclosure provides the ultimate protection from the elements. Aluminum’s natural corrosion resistance prolongs the life of your generator and is recommended for salt-air, coastal locations.

Generac has created
a controller for liquid-cooled models with an improved user interface for easier monitoring and management of the generator functions.

Comment by Jim C. on 9th Nov 2014

My Mom and Dad are both in their 80's and live in the country. With the installation of the 6551 I can rest assured that they will never be without power, heat, ac and water. this is a great unit and worked perfectly upon startup. Should have installed this a lot sooner for them.

By the way, my son-in-law also has one for his home. I live in a motorhome or I would have one also.
