    GE 15kW - 1, Derecho 2012 - 0
    I purchased this unit last year October 2011. The winter of 2011/2012 was very mild and we didn’t need it, but then came the “derecho” of 2012. With millions homes without power because of the storm, I felt great about the purchase my family made as we are enjoying our standby generator during this outage as our generator kicked in without issue. We would were without power for almost 5 days, but we were nice and cool as our generator ran our complete home, air conditioning and all. With local ... read more regulations, you need to have your unit 5 feet away from your house, so the doors all around isn't a problem. You want 360 degree access. I highly recommend this unit.

    Good unit, fair price, documentation needs a little work
    Everything worked great - took a while to wire and setup propane - but that was to be expected. When I ran test, I kept keep a fault code 8; called tech support and they had me set two dip switches that were not set - wish the doci had that bit of info. Outside of that the unit looks great and works great! Only Gripe is that Home Depot told me that it did NOT come with a pad. I bought a pad and the unit showed up with a pad.

    Product was what we wanted and are happy with what we got.
    I researched quite a few different models of generators and found that this one offered through Home Depot was the best one for us. I am looking forward to having it connected and prepared for back up as the winter starts in full swing.

    Warranty is excellent, as is the service if warranty is needed. Great product, works as specified. High quality materials and well built.

    service/functions
    i am on oxygen 24/7. in the past, i had to find my way down cellar to get on a different oxygen delivery system if i had a power failure. my neighbor had to take care of my gas generator as i am unable to do it. this wonderful generator has given me immeasureable peace of mind and being able to detect what is wrong from inside the house is awesome. philbrick's generators out of stratham, nh is my dealer and i could not ask for better service. all company of all types should take lessons from ... read more them as well as the team they have set up to install them from the electrician (s) to the fuel company. i am so pleased and happy. i will recommend this to anyone.

    Life Saver
    I purchased this G.E. backup generator because I have a daughter that has a need for refrigerated medication. If power goes out, her health cannot be jeopardized. This system gives the family peace of mind, and is a life saver when needed. It has performed flawlessly from the beginning and the small footprint is wonderful.

    Great Product ,Poor Installs
    I am a certified Generac Tech, although the generator is Rated to be 18" from a noncombustible surface and some of the pictures I see are not correct installs. code for Generator installs are 5ft from any opening be it a window or a dryer Vent for reasons of safety from carbon monoxide poisoning from the fumes . please refer to local codes when installing and get a Generac maintenance contract to insure many years of reliable stanby Power

    Nothing to complain about...
    Delivered in a timely manner (10 days) though I believe I was expecting it in around seven. I found through multiple estimates that it is cheaper to buy the unit yourself and then have it installed rather than get it through a thrid party. I finally had it installed for about $1900 which was far less than any other estimate I had been given. Unit works well... I had 2 small problems with the install but I am very happy with the product. Now I can count on the power not going out for at least a few years.

    True peace of mind and a great value
    I had one of these units on my home in Southeast Texas during an extended outage caused by a hurricane. The system performed flawlessly for days on end. It was so nice to have air conditioning, be able to wash and dry clothes, and not have the inconvenience and waste of spoiled food in the refrigerator and deep freeze. The generator required very little interaction during the extended run time except for the addition of oil, which we expected. I can't say enough good things about Generac or their products!

    Best purchase I ever made
    I purchased my GE Generator System after a visit to a 55+ Expo at Dover Downs in Dover, DE. I had thought about a generator and wanted a quote on purchasing one. While at the Expo I meet Nick Sebastian from Towles Electric Inc in Smyrna, De.. We set a appointment and Nick could not have been nicer. We purchased a 20k whole house generator from him. After Hurricanes Irene and Sandy 2 year's in a row I wanted peace of mind, that's what Nick and Big Bertha ( our generator) have done. I LOVE LOVE my ... read more generator, when the power is out we are comfortable and safe in our home.

    Great Product, Great Price,Great Company
    The unit is on our patio about 4' from the house, it has come into use three time and is just a little louder than our outside central A/C unit. We installed it after building a new home and loosing our last home to hurricane Ike. It's a true blessing, you don't realize how reliant you are on electricity until you don't have any. After living close to a month without electricity we will never have a home again without one. It's the heart of the house providing the ability to have A/C, ... read more heat,appliances, lights,hot water, and on. Thanks GE

    Neat appearance
    I called Mr Sparky and made an appointment. Mr Chad Blanton came out in a few days to discuss my gen needs. We came to a solution and he and Mr Dallas came back in few days for the installation. These two guys were very efficient and done a very professional job. They even replanted a flower that was in the way during installation. I was very pleased with their service and how neat and respectful they were when they replanted my flower. Mr Blanton came back after gas was installed and started ... read more the gen up. He was very helpful and explained things that I needed to know. These two guys were very curtious and professional

    Works well
    Seems well built and works perfectly. Only time will tell how it holds up in the weather here in NY. The installing electrician was happy with the support line, 'tho there were long waits.

    GREAT UNIT!
    My wife and I purchased this unit for our home in the mountains in San Bernardino, CA. We have had the unit since January, 2011. I have MS and I am disabled, we have chair lifts in our home and God forbid I need to be on a ventilator it would save me. The unit self test for 20 minutes every Saturday. It is quiet and really is white noise. We have had several power outages in the past year the longest lasting 5 hours in the middle of February in a huge, cold, snow storm. The generator kicked on ... read more right away and ran our whole house with no problems. It runs on natural gas so with natural gas you only get 18000 W but more then enough to run everything in our house and then sum. If you have the means and the need I highly recommend this unit!!

    Highly Recommended
    Got it earlier during the year. Installed it and wired it myself (with my son) but we got a plumber to extend the gas line. Total cost of the project including land-prep, battery, plumbing and electrical wires totaled to $4,500. Automatically exercises every week. People say having a generator is an insurance that prevents outages - during hurricane Sandy, we did not lose power, but the peace of mind was invaluable. All my friends who has seen how it switches the whole house automatically ... read more (during my demonstrations) were amazed. A must have investment against aging infrastructure and more frequent and severe storms.

    11kw generac
    delivery-good to store, good packing, good looking product, fits nice near the house, panel nice, gas hook-up easy, electric more on the hard side to figure but will make sure everything works good, the rest is up to the weather and electric supplier!!!!

    Well priced, excellent unit
    Received an excellent price on this unit thru the Pro Desk. Ordered at beginning of September & was received in an acceptable time frame-no shortage due to storms, etc. Had unit installed by an electrician and the local gas company. Relatively easy installation. Only been needed one time since being installed but worked flawlessly. Installed remote monitor for ease of mind. One point of interest: check the amount of fuel consumed and be sure that you have sufficient tank capacity for a 2-3 day ... read more run. Also notify gas supplier that you have the unit just so they are aware that you may need a fuel delivery during an extended outage.

    Generator and cost
    I am very satified with the product and highly recomend them. The price to actual use will be hard to justify however - when you need it it seems god sent! - Generac is not friendly to anyone in the aftermarket for technical information.

    Easy as pie
    I've had this unit for about a month now. Of course we haven't had a power outage. The once a week check running is quiet and seemless to me. So far it's as "easy as pie"

    Not Electrically Freindly!
    Let me first say what a wonder product this is. Once it was connected, just turn it to auto and wait to loose power. In less than 3 weeks after installation we lost power for over an hour and the unit functioned great. The generator is designed well mechanically for ease of service. The removable front panel makes servicing a breeze and the oil drain extension is greatly appreciated. I would have given this a 5 star rating except during installation it is not electrically friendly. By this I ... read more mean there is not much room to make wiring connections. The instructions state that you need two seperate conduits for electrical connections but there is only one access hole for this. Not sure why Generac didn't put in two? There should be more room to make wiring connection at the generator. Terminal access is very limited

    Great value and High quality
    We needed a reliable electric source for the winter months while we are on the road. After the ice storm of 1998 we were reluctant to travel. The Kohler name and the Home Depot’s great price were too hard to pass up. Installation was easy enough and the final connections were done by licensed contractors. The transfer switch works in less than 10 seconds so the power is only out briefly.

    It seems like a solid unit and looks very nice next to the house.
    Although we have not had a need for our Kohler generator yet, Seems to be working properly and was easy enough for a licensed Electrician to install. Home Depot does not carry or offer a group 51 battery for the generator. You would think one would come with the unit for the money.
