Generac's air-cooled automatic standby generators are manufactured to operate on a natural gas or liquid propane fuel source. Attempting to utilize alternative fuels to run the generator is not recommended; doing so will immediately void the product's warranty.

The loads required in a house will vary, and are not determined by the square footage of the home, but are determined by the items you deem necessary to run in an outage situation. To properly determine the correct generator for your needs, we recommend working with a certified electrician in your local area. For help locating a certified party near you, contact us directly at 888-GENERAC (436-3722).

Great Gen.
Great system works great. Have had one power outage and it was about 24 deg. And it started first time ran about one hour and you couldn't tell that the power was off. I bought mine during to time that it had a 10 year warranty.
by Ghostrider
Makes me fill protected
The unit looks great..I live in the country where the power goes out quite frequently..so now I never even think about when we have bad weather..Only had it for a year, so I can't comment on maintenance or reliability. I have not had any problems. I have a geothermal HVAC system and the well pump is tied into my shop therefore I need to transfer switches to power both my home and my shop. With the underground power it makes for neat installation. Very pleased.
by Bill
Makes Us Feel More Secure
We have only had our GenerAC whole-house unit for 6 months and only had to use it once but the feeling that our basement will no longer flood when the power to the sump pump goes out during a storm or that we can still flush when there's no electricity to run the well is very satisfying.
by Dex
Best value on the market
Generac is consistantly a great product to install and enen better value long term.
by Agenerator
Great
I've had it since spring 2016 first test on our New England nor'easter 1/24/17 thank god it was just 60 mile an hour winds and rain and not snow kicked on twice in one day worked great neighbors on now envious
by Sparky
Great Generator
Good, reliable, high quality backup power source. Installed on high concrete footing for easy access and snow avoidance. Would prefer if the top cover had more of a crown to prevent standing water... also, would prefer self-adjusting valves. Bottom line - Works as advertised... would recommend.
by GenAnTonic
Wonderful
Everything as advertised ... Great communications ... actually looking forward to the power going out now
by lolox2
One of our best purchases ever.
In the last five months we have lost power six times. My wife and I talked about getting a generator but thought they would be way to expensive. Boy were we wrong! When I told my wife the price she said "order it" Four days later it was here and two days after it was installed. We have the 16,000 watt Generac with the whole house transfer switch. IT RUNS EVERYTHING. Very Very pleased.

Whole-House Standby
My Generac Standby Generator is off to a good start. We have it completely installed and have run the whole house from it for about an hour. It appears to perform as advertised, but one hour doesn't really tell us how it will do after a hundred hours. I expect no problems, though. The installation is not difficult but there's a lot of work. The Generac manuals say, "Only qualified electricians. . .should attempt installation!" They mean it. Unless you are well versed in wiring branch service panels and dealing with the National Electric Code, you shouldn't attempt it. I did but I'm an electrical engineer with much wiring experience. There are some things you can't get from the Generac literature: the long front opens for engine access so it needs space in front; the breaker panel is on the outside of the right end; the electric and gas inlets are on the back near the right corner (as seen from the front); the output breakers are 65 amps so #6 AWG wire to the transfer switch is sufficient, even for a 200-amp switch; the package weighs almost 500 pounds; the base dimensions are 48 by 29 inches so the concrete pad needs to be several inches larger; six conductors #18 AWG rated at 250 vac are needed for control wires from the transfer switch to the generator. These are all questions I had while planning the installation before ordering. The overall work, from placing concrete for the pad to running 60 feet of 3/4" conduit under the house to installing the transfer switch to running the generator power and control wires took about a dozen hours. My installation supplies the whole house through 200-amp service. Shifting the mains from the top of the entrance panel to the transfer switch and then connecting the transfer switch to the entrance panel requires you to work with #000 AWG wire, which can be a struggle. That part of the installation took over two hours and a couple of skinned knuckles. Once everything is installed, testing is straight forward and the system ran properly as soon as programming its controller was finished. You must perform the authorization-code step. Materials for installation totaled about $600. My time is free and our daughter's help is priceless!

Response from GeneracMar 23, 2015
We are happy to learn of the positive experience that you have had with our automatic standby generator and associated transfer switch. As you have alluded, we would always recommend utilizing qualified electricians for installation purposes. Also, please note that the wiring and configuration of each installation will vary from one setup to the next, as local codes supersede any of our recommendations as the product's manufacturer. Lastly, please note that the information that you were unable to locate in the product's literature is in fact provided in the unit's documentation. If you would like to receive this literature for future reference, please do not hesitate to contact us directly at 888-GENERAC with the model or serial number of your personal unit. Lastly, to ensure that you have registered the unit properly with Generac Nation, please provide the requested information at the following link: http://www.generac.com/generac-nation-sign-up?cid=frm-100-aa Generac

Best move I ever made
I use to use a 8 K welder generator to keep power running in the house but I had to be home to connect it. I travel all the time not fun getting the phone call from Mrs. I connect this up and could not believe how well the switch and generator reacted to an outage, and how it handled the load. I highly recommend this generator and switch.
