Guardian 22 kW Generator Features and Benefits

The 22 kW Guardian® Series home standby generator is the largest air-cooled home standby generator on the market. Not only does it deliver all the features and functionality customers have come to expect from the market-leading brand of home standby generators, but with an MSRP that is the lowest cost per kilowatt of any air-cooled home standby generator. Provides whole house coverage for many homes.

Guardian 22 kW Generator <strong>Features and Benefits</strong>

Lowest Cost Per Kilowatt
Homeowners can invest in a home standby air-cooled generator size that used to only be available in much more expensive, liquid-cooled models, giving them the lowest cost per kilowatt available.

Generac OHVI® Engine
Your Guardian Series generator might have to get you through days—or weeks—without utility power. Generac’s OHVI® engine, specifically designed for generator use, provides the reliability to power through the most severe outages.

True Power™ Technology
Best-in-class power quality with less than 5% total harmonic distortion means clean, smooth operation of your sensitive electronics and appliances.

Evolution™ Controller
The next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons.

Certified for 18" Installation to the Home
Third-party certified to NFPA standards to be installed as close as 18” from the home’s exterior wall, provided it is located away from doors, windows, and fresh-air intakes, and unless otherwise directed by local codes.

Easy Installation
When combined with a pre-wired transfer switch or Smart Switch, re-engineered connection points, and composite mounting pad that eliminates the need for a poured concrete base (unless specified by local codes), the Guardian Series 22 kW generator is easy to install.

Rated for Operation in Areas with Low Natural Gas Pressure
In areas with low natural gas pressure, the Guardian Series 22 kW generator can operate on natural gas pressures of only 3.5” of water column.

All-Weather Aluminum Enclosure
Our durable powder-coat finish helps make the sturdy, all-weather aluminum enclosure corrosion resistant, making it ideal for coastal, salt-air climates. It’s also able to withstand 150 mph winds.

Tool-less Fuel Conversion
Switch between natural gas and LP fuel in the field in a few seconds, without the need for any tools.

Quiet-Test™ Mode
All standby generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Guardian Series home standby generator runs its self-test at a lower, quieter RPM than standard operation, and can be programmed to run weekly, bi-weekly, or monthly.

Mobile Link™ Compatible
Take advantage of Generac’s Mobile Link cellular remote monitoring system and check on your generator’s status using your computer, tablet or smartphone, even when you are away. Sold separately.

Non-cellular remote monitoring options are also available for generator monitoring from inside the home.

24/7/365 Customer Support
Power outages don’t always occur during normal working hours. That’s why Generac’s customer care call center—right here in Wisconsin—provides support any time of day or night, all year long. Generac is standing by 24/7, every minute of every day, to answer your questions.

5-year Limited Warranty

Home Generator Buyer's Guide

Included with This Generator Bundle

Gain up to whole-house coverage through smart power management. If it is unlikely you will turn on every appliance at the same time (most people don’t), a smaller generator paired with a Generac Smart power management transfer switch provides whole-house coverage through a managed power solution. The process is simple - non-essential circuits are shed when the generator approaches maximum capacity to eliminate overload, then are cycled back on when essential circuits are satisfied. Give yourself a little more than just the basics without a substantial increase in your investment.

Rated 5 out of 5 by from Peace of mind for our family. As a natural gas utility worker, I have seen first hand the crippling impact that power outages can have during ice storms. I now have the peace of mind knowing that my family ( including a mental and physically disabled adult ) is in good hands when I can't be there.

Rated 4 out of 5 by from good product bad item The 22K generator was installed in october. It ran very badly. It took 4 to 5 visits by the installer before a second company determined that the Mags were bad. This second company charged me $150 to determine this problem. The Mags were replaced by the installing company and it seams to be running well. All this took three months to resolve. Good product bad item.

Rated 5 out of 5 by from It's a big unit in a small box So far we are well pleased with the unit, the auto no load test works well. We look forward to this test every Monday at 10:00 AM, when this happens., it gives us the good filling that we just might not be left in the dark anymore. We have had one loss of power since the install, all systems performed as designed. Thanks Jack

Rated 5 out of 5 by from This product has everything we need The only accessory I would like to add is an app and WiFi connection that would notify me when an event involving the generator has occured.

Rated 5 out of 5 by from Highly Satisfied! I purchased the first unit for our home and a second unit for our cottage, about a month later. The units are performing great, they are currently set to cycle on for 5 minutes once per week. Had one very short power loss at our house and the generator did its job. It started within seconds of the power loss and shut down promptly after the power was restored. I am very satisfied with the design of the unit and the installer did a great job!

Rated 5 out of 5 by from This generator is awesome. After contacting generac by e-mail. I received a reply. And was set up with a certified dealer. Everything went very well. I would recommend this generator and installation by Billy Cooper to any one.

Rated 5 out of 5 by from Sleep Better Knowing Power Is Thete Installation was very straight forward with our installer. Looked better than other installs I had seen in the past. Unit is definitely quiter and more efficient too. The 10 year warranty Is amazing and is certainly a manufacturer testimony to the quality we can expect to receive from this unit.

Rated 5 out of 5 by from A whole hse Generac, and how we feel abt it Our power went out and the generac cut on within 3 sec, as the contractor said it would. It did make a loud clunk sound when it cut over, and the generator does make some noise. The clunk sound woke us and the dogs up, and the generator is close to a bedroom, so it did disturb our grandson. The cut-over box (on the outside) is just outside my bedroom, so explains why it woke us and the dogs. Other then that, it works great, and a small price to pay(being woke up) for keeping power on. I love the looks. Contractor was very thorough, and helpful. We needed a new elect panel, so he took care of it. Also needed a larger gas meter and line put in, and he made all the arrangements for us, with our permission. I highly recommend this contractor. We have a neighbor that has a young child, so happy it has locks on it. Our town is known for power outages, so very happy we had it installed.
