Guardian 8 kW Generator <strong>Features and Benefits</strong>

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, 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 8 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 8 kW generator can operate on natural gas pressures of only 3.5” of water column.

All-Weather Steel Enclosure
Our durable powder-coat finish helps make the sturdy, Galvanneal steel enclosure perfect for all weather conditions. 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.

Quick, Quiet Exercise Test
Standby generators require a short run-time periodically, known as exercise, to test and ensure the system is functioning properly and ready for an emergency. The Guardian 8 kW self-test runs for only twelve minutes. Choose your schedule - 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 Love it We switched from oil to gas in August of 2012, and had a new high efficiency furnace installed... But also decided to install this 8kw generac just because in this area of Eastern PA there's way too many trees within the power lines, and of course the storms in the past 2 years have put out power for several days. It worked for the first time during hurricane Sandy (power was out for 4 days). It turned on with in 10 seconds and worked flawlessly the 4 full days. Great buy and great value. It really is tough to not have electricity and the unit was great for the simple reason that we 3 year old twins.

Rated 5 out of 5 by from Excellent Economical Upgrade We upgraded to a Generac 6237 generator during a house addition. Since its installation 15 months ago, it has reliably turned on automatically and powered 10 circuits every time we lost power. One of the outages lasted for 1 1/2 days. Fueled by NG, I never had to worry about refueling it as I would have with the gas portable generators we had before. And of course, being an automatic generator, it shut itself down when line power was restored. Not having to setup the portable generator cables anymore is a major relief. The automatic generator backs up the refrigerator, freezer, furnace fan, small hot water heater, Internet gateway with TV, garage, microwave, ceiling fans, some lights and electrical outlets. All these circuits are 120 volts and enough power for our use. It will not power our AC, and we knew it would not when we bought it. My wife and I live alone and not having AC for short periods of time is minor to us. We have a small portable AC conveniently stored in a closet. It is easy to move and setup when needed, and it cools one room comfortably. We live in a heavily wooded area in Atlanta with many power outages over the past 34 years. We have had two portable generators in the past 20 years that provided critical power when needed. But even with the newer one with a manual transfer switch, it was a chore to fuel it, keep fresh gas on hand, protect the unit from the elements, and decide when to start and shut it down. The Generac 6237 does all that work now. Looking at the outside and inside of the generator enclosure, it is easy to see Generac engineers and builds quality. It looks good, and the inside compartment is clean and neatly organized. This is a quieter unit compared to any other generator I have ever heard running. Priced at the low end of the Guardian series, the 6237 balances excellent quality and enough backup power while remaining economical enough for us. Recently, a Generac dealer performed our first maintenance.The service tech changed the oil and filter, refilled it with synthetic oil, serviced the battery, and checked and set the valve lash. He explained the control panel operation and answered all my questions. He informed me that properly maintained and serviced, these units can last 15 years or more. I plan to always have the scheduled maintenance in the manual done. So, I am very confident that our Generac generator is a good investment that will continue to provide us reliable backup power for many years to come.

Rated 5 out of 5 by from Peace of Mind From start to finish, we were very happy with the installation of our Generac generator. Since it's installation within the past two months, we have experienced two small power outages. Hearing the generator "kick in" put a smile on our faces knowing we were prepared. A great decision, a great choice.

Rated 5 out of 5 by from I am no longer terrified of power failures We had three power failures between the day I ordered and the scheduled installation and it was not More than a couple of weeks. I worried so because my husband has spent 5 months in the hospital this last year, and I was feeding him through a mediport in his chest. Each bag was $1,000 and required refrigeration. I now have total confidence in keeping his medications safe. I have not had a failure since we have only had it less than a month; but now I can't wait for a power failure. I can't wait to turn on the lights and watch the neighbors sit in their dark homes. Bad attitude I guess! I used to laugh at my daughter when she would say the same thing. She would say "I love power failures" Now I can agree!

Rated 5 out of 5 by from Early stages of use, but so far so good.......... I had this unit installed by a local dealer about two weeks ago. Up to this point I have not had to rely on generator power, but we feel very satisfied that when the time comes that we do, we will be well prepared with our new Generac unit. The peace of mind alone was well worth our investment. The unit is sleek, looks good in the yard, installation seemed easy by our dealer, and the unit performed flawlessly during our testing and at the weekly exercise time. Extremely pleased as this point, we will reserve full judgment for when the unit is required during a power outage. Until then, so far so good.......

Rated 5 out of 5 by from Very Happy I choose Generac My home just had a 8kw home backup generator installed with natural gas. This generator is easily powering the essentials in my house (furnace, well, sump pump, hot water heater, radon mitigation, 2 refrigerators, and 1 deep freezer). There was still circuits to spare so some outlets and lights are working in the home with no problems as well. I'm very pleased with this purchase and have no worries about the quality, comfort, and longevity this will bring to my home and family.

Rated 4 out of 5 by from It has been there when we needed it! The generator has been reliable in each of the power outages that have occurred in our neighborhood. It also looks as good as the day it was installed thanks to A-Z's maintenance.

Rated 5 out of 5 by from Finally, a product and service you can rely on Every so often a product is delivered, installed and made ready to use by factory trained personnel. This generator met all our needs, was reasonably priced and was installed by professionals. Not only is it reliable, it also sets ones' mind at ease when living in areas prone to bouts of severe weather.
