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 Great Generator for the money paid Great installation job by the company I selected. Only twice has the generator kicked in but each time was a source of relief knowing I had power. It is the 22kw air cooled and seems to power the house entirely, at least the appliances I had to use and the cooling/heating system. Lag time was approx 30 to 1 min but there was power thereafter. Just long enough where you do have to reprogram the clocks on the microwave and stove, etc. The generator is situated in a nice outside structure which seems durable. I also liked the fact it was bolted to the cement and there was a shroud that covered the bolted area. It is associated with some noise but is markedly different from the portable generators (my neighbor has one and I can hear it clear across a field at least 200 yards. Appears to be low maintenance with the generator cycling to check itself I believe twice monthly. I have yet to see it cycle. Will contact the installation company when oil change , etc is needed. Overall, I believe it was worth the investment for piece of mind and also safety and comfort. So far looks good and works great.

Rated 5 out of 5 by from This product has a great appearance. We are very pleased with this generator. We have not had a need for it yet, but are very confident that it will operate as we were instructed. We are also very pleased with the electrician in his installation. He is very knowledgeable and precise with his work.

Rated 5 out of 5 by from Great Product Great product, love not having to worry about a power outage. The generator is a good price for the great quality and features. You can tell a lot of planning went into the way the generator is built and packaged for the delivery.

Rated 5 out of 5 by from Ready when you need it Only came on a couple times so far, but certainly comforting to go from sitting in the dark to full power in less than a minute. Thanks!
