Product Details

Generac Guardian 8kW Without Transfer Switch - 6245

Provides essential circuit power protection for your home, ensuring the necessities remain powered during an outage.

Features:

  • Generac OHVI® Engine
    Your Guardian Series generator might have to get you through days—or weeks—without utility power. Its OHVI® engine, specifically designed for generator use, provides the reliability to power through the most severe outages.
  • 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
    With an intelligent 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 11 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 11 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 confitions. 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.
  • 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.
  • 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.
  • 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.

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.

We've had our residential backup unit for about four years. It often doesn't start at all in really cold weather (it's supposed to run automatically for ten minutes once a week). We have the service people out when we notice this happening, but that hasn't seemed to help. I don't know if it's been this way since it was installed, but we've definitely noticed it in the last couple winters. We just had our annual inspection and got hit for $600 for a new controller board because the choke supposedly wasn't operating correctly. All in all, if doing it again, I would seriously look at other brands. We went with a terrific local dealer who has done a lot of work for us and our employers. No problem with the dealer. But I do have questions about the hardware's reliability. Cold weather is probably the likeliest time for us to have a power outage, and we're not confident any more.

Let the winter storms come

By 

from Wolcott

Comments about Generac Guardian 8kW Without Transfer Switch:

I live in a rural area where electricity outage is a habit. My Generac allows me to sleep without worries. Every Saturday the generator comes on at 1:p m notifying me that all is well. So far two of my neighbors have purchased one and we compare notes, everything is fine on the hill and the lights are shining brightly. The product is great but even better is the customer satisfaction whenever I call Generac, I have one person assigned to me and all questions are answered. They have honored their warranty without any questions. If you don't have one you should get one.

Keeps your beer cold.

By 

from Kitchener

Comments about Generac Guardian 8kW Without Transfer Switch:

During a recent power outage a neighbour approached our front door to ask how we still had power and he didn't. I explained about our Generac back up generator. I said I still had the ball game on tv, A/C, and cold beer in the fridge. He remorsefully said he had no tv and no A/C but had cold beer in the fridge if only his wife would let him open it to get a beer out. When the power goes off you don't always know for how long it will be off. With a Generac back up system these issues are no longer a concern

Best Generator on the Market

By 

from New Baltimore

Comments about Generac Guardian 8kW Without Transfer Switch:

We purchased the 8kw generator in September of 2014 and had it installed 1 week later. Our timing was great because we lost power 5 times in the next several months. Everytime we lost power, the generator started within 1 minute of powerloss and continued to run until power was restored. The Generac generator provides all the power you will need and gives you great peace of mind.

I AM 80 YEARS OLD, AND MAY BE ON VACATION OR IN THE HOSPITAL MY HEATING SYSTEM WILL NOT WORK WITHOUT ELECTRICITY IF MY ELECTRICITY GOES OFF IN THE WINTER, MY PIPES WILL FREEZE AND BURST, AND MY HOME WILL BE RUINED THAT WILL NEVER HAPPEN WITH MY GENERAC, WHICH IS WORKING BEAUTIFULLY SINCE IT WAS INSTALLED

8KW Generator

By 

from Brewster

Comments about Generac Guardian 8kW Without Transfer Switch:

I have such peace of mind with my Generac 8KW. It starts right up when the power is out. If it happens during the night, in the morning I don't even realize that my power is through the generator.

Good unit, but did have some issues

By 

from Moorefield

Comments about Generac Guardian 8kW Without Transfer Switch:

The product works well. It provides all the backup power I need. It takes over automatically, tests itself weekly. It was exactly what I wanted and it works. The issue I have had is that the weekly test cycle fails and after 6 months and finally 3 support visits the control board will be replaced tomorrow. Hopefully I will have no more issues after that.

Original motor failed shortly after two year warranty. Costly replacement motor.. Hope the new one works for a long time.

By 

from Blowing Rock

Comments about Generac Guardian 8kW Without Transfer Switch:

I purchased the 8kw with a two year warranty from my electrician. Shortly after two years the motor failed even though there was oil available. At a cost of $650 a new motor was installed and I have not had to use the generator. I was told that I have a new warranty.My fingers are crossed that it will last a long time with no more problems.
