Generac Protector 22kW QS Standby Generator

Automatic Backup Power For Large or Custom Homes
Looking to back up your entire home, or more items than usual? Consider the Protector gaseous automatic backup generator line. These units powers essential appliances and modern technologies during power outages, allowing homeowners and their families to continue living life comfortably and without interruption.

What Makes the Protector Series Such a Great Choice?
Generac's Protector Series offers benefits that competitors can’t match. Installation flexibility and cost reduction. Sophisticated, yet intuitive controls. Quiet operation. Supported by a 24/7/365 customer support team at our corporate headquarters, and a nationwide dealer network of more than 6,000 strong.

The best liquid cooled engine packs more power into a smaller footprint - ideal when space is a premium.  The neutral styling, color and small footprint fits unobtrusively into landscaping. Clean burning, continuous fuel choice of natural gas to LP.

True Power™ Technology
Delivers best-in class power quality with less than 5% total harmonic distortion (THD) for clean, smooth operation of sensitive electronics and appliances.

Evolution™ Controller
A cutting-edge, intuitive control. The Evolution controller features a multilingual, two-line LCD text display with color-coded, backlit buttons. It has received upgrades, including USB flash capability, smart battery charging, voltage adjustment, and backlit membrane pad style buttons.

5-year limited warranty with extended warranty options available
We are proud of our innovative product design, high quality and first-class reliability so we stand behind them with a strong 5, 7 or 10-year limited warranty.

Can Be Installed Just 18" From a Structure
Capability to be installed 18 inches away from a structure, ideal for areas with tight lot lines.  Generac’s is the only manufacturer of standby generators to have 18” offset on most of its residential lineup.

Tough, Durable All-Aluminum Enclosures
Our RhinoCoat™ powder-coated finish helps make corrosion-resistant aluminum perfect for all weather conditions.

All backup generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Protector Series home generator runs its self-test at a lower, quieter RPM, which can be programmed to run weekly, bi-weekly, or monthly.

Mobile Link™ Connectivity
Comes standard with all Protector Series generators. Mobile Link allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet or PC. Easily access information, such as the current operating status and the generator’s maintenance schedule. Connect your account to an authorized service dealer for fast, friendly and convenient assistance. With Mobile Link, your generator is taken care of before the next outage.

Additional Features
Improved stub ups and electrical connection access decrease installation costs. All connections are dual conductor rated, and the implementation of quick connects for the control wires, completely eliminates the need for crimping or lugging.
Improved customer connection access, which decreases installation costs.

Rated 5 out of 5 by from Ease of mind recommended by two friends with similar unit who give it high rating. My wife and I are in mid 70's and both use C Paps for sleep apnea. In addition, this will ease the inconvenience of flashlights and candles, /The installers were kind and professional..

Rated 5 out of 5 by from Just what you need for emergencies! I needed a power source for my wife while I am out on emergency calls. This powers my entire residence automatically. No mess. No fuss. Reliable. What more could I ask for!

Rated 5 out of 5 by from Top of the Line The generator had been installed less than a week when a wind storm knocked out power to our village. The Generac started up on Q, and supplied us with all the needed power until WE Energies got us back online. Flawless.

Rated 5 out of 5 by from Peace of Mind We've had ours for nearly two years now and the power outages are becoming more routine here in northern Calif. If it isn't PG&E doing preemptive shutoffs due to winds, it's forest fires like the one we lived through here, just last week. Originally we were going to buy the air-cooled unit of the same output, but my electrician gave me a heads up on this liquid cooled unit and it has paid off for us. The lower dB level plus the extended maintenance schedule is a must when you are making power 24 hrs/day, multiple days in a row. This machine is built to take that duty cycle. We use propane and it can run into cost, but it is really cheap peace of mind for us and I have no regrets on buying this machine. Now my neighbor has the same model and he thanks me for educating him as well. Me too because his is just as quiet as mine.

Rated 5 out of 5 by from Quiet and Powerful After a great deal of research I settled on the liquid cooled 22kW natural gas powered generator. Quieter and longer lived. I also opted for the extended warranty as well. Very happy.

Rated 5 out of 5 by from Performed flawlessly Had our 22 kw liquid cooled Protector QS installed 4 years ago. Don’t remember if we ever had any outages longer than a day or so. It has always run great. We got the true test during Hurricane Laura. We left the morning before the storm hit. It was nice to comeback to a home with minor damage and a generator running just like it was supposed to. All in all it ran for 7 days and never missed a beat. Thank you Generac for making such a quality product. FYI , scheduled maintenance was performed during the outage.

Rated 5 out of 5 by from 7Years old and still going strong I've had my 27KW for over 7 years and it's still performing excellent. We have the annual maintenance with our generator installer (Reliable our of Deerfield FL) and I could not be happier. Two years ago, it ran for 10 days consecutive and never missed a beat! Highly recommend.

Rated 5 out of 5 by from Natural Gas 22KW I live in south Louisiana and have been plagued by un-reliable electrical power. It seems that most storms, of any size, disrupt the power and on average it will be out for a minimum of 6 to 8 hours. My area is usually the first to ho out and the very last to have power restored. My Generac 22KW QS unit works great. We have had 3 power outages in the past year, and the generac unit picked up and handled the load without any problem.
