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.

Rated 5 out of 5 by from Extremely quiet - functions perfectly After losing power for the 4th time this summer, I bit the bullet and installed this generator. I am embarrassed to say it took me this long - it is a real life saver. With a 1 yr old toddler running around the house, I feel so much better knowing that we'll have continuous power during the heat of the summer and cold of the winter. It runs very quietly, you can't even tell it's on - except when you get the alert on your iPhone when you get the attachment that connects to the cloud for notifications. Really cool that it alerts me every week when it starts it's test and when it finishes. Very happy with the product.

Rated 5 out of 5 by from Peace of Mind / Security Provided Power in our area goes out several times a year. We've had to check into a hotel foe days at a time, plus the added cost of lost food in the refrigerator & freezer. in addition our major concern is that our Alarm system's back up battery is only good for 24 hours - thus when the power is out over 24 hours our alarm system doesn't work. For all these reasons we decided to have a Generac standby generator installed. Two days after it was installed our power went out - but only for a few seconds for us because we had the Generac - Our neighbors were without power for hours. It works very well, looks good and provides that peace of mind we were looking for - Thanks Generac.

Rated 5 out of 5 by from Attractive, relatively quiet, convenient It means everything to me, living alone and a senior, to have the peace of mind from this unit. I spent a lot of time last winter alone in the dark and cold and uncertain of the future during several lengthy power outages. I decided I never wanted to go through that again. On another person's recommendation, I called Generac and told them I knew nothing and needed a lot of information. They couldn't have been more helpful. Everything was handled with utmost professionalism. In short, it is worth every penny to never have to live without power and water again.

Rated 5 out of 5 by from The 22KW generator has all the features I need for all house functionality. We live in a rural area where power is lost several times a year due to summer and winter storms. So, when I watched the TV Generac promotional ad, I knew I needed to call for more information. Customer service put me in touch with a local authorized dealer/servicer and the rest is history. Now with the purchase and installation of our Generac automatic standby generator (22KW), we feel safe and secure when these storms occur. I would recommend purchasing the generator from an authorized dealer/servicer. These professionals must meet all Generac technical training certifications for the smooth installation and running of all the generators.

Rated 5 out of 5 by from Peace of Mind Worth The Cost My husband and I live in a rural area prone to frequent power outages due to wind, ice and down trees. After suffering through 6 days of freezing cold last year with pipes frozen, no heat or water and no power other than a small, portable generator, we made the decision to purchase the 22W Generac Stand By Generator. We now have peace of mind knowing our whole house is protected from power outages and we can be warm and comfortable. I look forward to the weekly test runs as this serves as a reminder that our whole house is protected. Thanks to our local service company for their great service and friendly support. We can definitely recommend this unit to our friends and neighbors.

Rated 5 out of 5 by from Peace of mind! A whole house generator is truly a purchase that relieves the stress of what will happen when power is disrupted.

Rated 5 out of 5 by from Praises for Generac I purchased my generac in 2012 after a tropical storm put me out of power for several days. Now that I am retired, being without power stressed me out. So I called my local generac dealer and purchased a whole house generator. The peace of mind I have when a tropical storm threatens is absolutely wonderful. I have lost power on 2-3 occasions for several hours. The unit didn't miss a beat. Thank you generac!

Rated 4 out of 5 by from waited too long to buy it had the first black out and generator started in 5 seconds. It was a great feeling when all around me power was out except for us. The black out stress left in seconds.
