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
Mobile Link™ Connectivity 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, our generator is taken care of before the next outage. 
Mobile Link™ comes standard with Protector Series 22-100 kW gaseous models and all diesel (RD) models.  The Wi-Fi device is standard on every Protector series generator except for the RG13090/RG15090 and the 130 – 150 kW gaseous models.

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 Appearance blends with yard. With tornados in the area, and trees and wires down, it is really most comfortable to know the generator is standing by to keep sub-pumps operating in an emergency situation.

Rated 5 out of 5 by from Great investment We live in the foothills of Monrovia and power outages are inconvenient. Fire season is nearly year round. It is evident that Edison will be quick to shut down service at any sign of danger. To avoid "sleepless nights" we investigated full house generators and nothing came close to Generac. LT Generator was great to deal with, from the initial walk-thru and explanations right up to the final signoff. Our installation date fell right into the monsoon conditions last December and LT dealt with enormous challenges to work around them. The inside staff were great to work with and kept informed at all times. They arrived exactly when they said they would and worked past dark a couple of times. When done, the unit fired up and worked flawlessly. Said a lot to me about the professional quality of the entire crew. My next door neighbor watched the progress and was impressed. His identical unit was installed in mid-February and he had the same pleasant experience.

Rated 5 out of 5 by from Harrington Electric Asheville, NC Rick, Alan and Billy did a great job with install and cleanup. Rick reviewed the buying and install process. Install took one day. Asheville inspector approved install 48 hours after installation. I would definitely recommend Harrington Electric for Generac install and other electrician needs. 22KW was tested as part of the install process and generator set to automatically test bi-weekly based on homeowner custom times.

Rated 4 out of 5 by from Wifi set up The problem we're having is setting it up to the wifi system. You have to use your phone to activate the Generator and on the phone it ask for a code, we put in the code that was sent via email and it will not go to the next step so we can program the Generator. Our Electrician is having the same issue and is having to wait 30 minutes for technical support. There should be an easier way to program these Generators.
