    Kohler quality and reliability is apparent in this generator
    The Kohler generator has all the features (and then some) of any other unit on the market, which included a quality transfer switch. The 5 year guarantee is also a great feature as nearly all other generators only offer a 1 (sometimes 3) year warranty. It is easy to install and program and is not very loud when running under load. The plastic outter shell is well insulated against noise and the plastic mounting platform (like the outter shell) is corrosion-proof, a "must" in the wet Florida ... read more weather. Even with the purchase of the wire, conduit and fittings, the Kohler generator was competively priced.

    20,000-Watt Standby Generator with 200Amp Whole House Service Entrance Automatic Transfer Switch with Load Shed Kit
    This Kohler unit was shipped on time and with much care. I can not say enough about this product. The manuals were easy to understand and also to implement during the installation. it is a project for individuals with skillsets for this kind of work. but when it is up and running this Kohler 20KW stand by generator is a "peace of mind" gen-set when your power goes out. We live in Western NY and the winters are harsh at times, with ice storms and power grids fluctuating and going out from time to ... read more time. So this installation was a no-brainer. If you can afford it we highly recommend using Kohler products, they are very well made and have a great warrantee.

    nice package with automatic switch
    this unit works well, nice design easy installation built to last . lost power muiple times up to 30hrs at a time it turned on and off automatically as it supposed to when power was restored or lost the only thing is during install there is no tech support to talk to kohler sent a tech onsite for a question that could have been answered in a second the service call was free

    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.

    Great Product - Does what is suppose to do
    The Generac 17kw is fabulous. It will power 16 circuits in my house (200 amp panel). I have ran the A/C, stove, microwave, outdoor lighting, 2 tv's, a computer, refrigerator and all downstairs lighting, upstairs lighting and a hair drier all at once with no noticable effect on the ability to run anything. All 16 circuits powered beautifully at once. Unit also has an external plug (15 amp) that may be of use and may be used by neighbor to help them out. Noise level is great. It is located about ... read more 15 feet from my living room and you can hardly hear it with the tv on. I was expecting it to turn on this past saturday and had to mute the tv to verify it was running. It sounds about as loud as a mower 3 to 4 doors down. That's not bad at all. Neighbors can hardly hear it. Super product. Beware...Track your usage as my installer said that Generac is very picky when it comes to warranty claims. Be sure to keep all receipts for servicing etc. and a run log. Installation of the transfer switch is definitely NOT a DIY project. My locality requires electrical and gas inspections after installation and before unit is fired up. A good install company will include all permits in installation costs. Depending on your circumstances and property (how far lines have to be ran etc.) it would not be beyond expectation to expect install costs for this generator to run from $7000 to $8400 (including generator costs) depending on your circumstances. If more, get a second quote (I'd advise that anyway). This range is for NG. propane tanks to be sure will add additional costs. Expect the 20KW generator to run around $1-$1.2K more (including the generator). Ask about any additional extension on the manf warranty from your install company. Mine offered an additional year parts and labor (from 2 to 3 years). Do your research for your area. But this is a super great product!!! It is costing about $3-$4 per month to exercise each week. My house is about 2100 sq ft. It cost about $20-$30 per day to operate during an outage. This is certainly cheaper than a portable. If you are in an earthquake zone you should consider propane backup if generator will be powered with NG. If gas lines are damaged you will have a backup fuel source). One other item, your a/c will likely require two circuits, as mine does. The furnace fan will take another one. That leaves you with 13. That handles all my needs. Washer and dryer (you should have enough clean clothes to last a week or two) would be doable with the 20kw as you have 4 more circuits (dryer will likely take two). The only kitchen item I left out was the dishwasher (not crucial for a few days). If you can live without the laundry and dishwasher, you can save approximately $1k-$1.2k for the 20kw. If not, you may want to consider the additional cost of the 20kw. Hope this helps. These are answers to questions I had going in. Kaos

    Wonderful Product
    I had mine installed and what a true pleasure. The local electrician I had hired arrived on time and did a professional job as did the local plummer in hooking up the gas line. Starts every Saturday at 10:00am and runs for 10 minutes.

    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!!

    Great Generator and Switch
    Had this installed at my home in southern Ontario in November. Just this past weekend the ice storm hit and if it wasn't for this generator, we would have lost power for 28 hours. It kicked in about 20-30 seconds after the power went out, and kept running continuously with no issues all day in into the next morning when power was finally restored. Couldn't ask for better, the rest of the houses on our street were dark and we running normally. For the peace of mind and comfort this brings, it is a great deal.

    Generac Generator
    Generac 11KW generator: Installation is pretty straight forward for this unit. If you are installing this yourself you should have w working knowledge of wiring (high and low voltage), Plumbing if you are installing LP or NG, local codes and permits, if you install main auto transfer switch the power must be disconnected to rewire the panel and an inspection must be done before the power is reconnected. The installation does take some time to do it right but is well worth it for the peace of ... read more mind in an emergency. Be aware of the additional expense of the materials needed for the installation and inspections. VERY HAPPY WITH THE UNIT.

    Installed and Ready
    Earlier in the year, my wife and I decided on having a backup generator installed. We opted for a unit that provided the basic backup features in case of a power outage. Since moving here just over a year ago, we have already experienced four outages and with a blind elderly mother living with us, that makes life difficult. After some research, we decided on the size and made the call. Our selected dealer / installer responded immediately and after their survey, we completed our selection and ... read more set up the installation date. We now have a brand new generator installed and doing its weekly test run. So far, since the installation, we have had no outages but there have been plenty of opportunities owing to the spring storms in our area. We are extremely pleased with the installation, the installer and the services they provide. If we never need the generator, that is fine by me but I know it is sitting there ready to go if we do.

    Awesome Features!
    We decided to purchase a generator after Super Storm Sandy. This generator made us so happy we did. We've had some prolonged power outages since our purchase and it has proved to be an asset in our home. We have alot of outages where we live and a generator is a must! We're so glad we chose this one, it's fantastic. Thankyou for making such a great product.

    Great little pkg.
    If you are considering a GE generator you should know before you place the non-returnable order that the warranty is void if the install is not signed off by a plumber, electrician and the local officials. It was my intention to do the install and rough in the electrical and have a licensed electrician do the final inspection and connections, but without the signatures of the local officials and the plumber I have no warranty. This did not come to my attention until after the unit arrived and I ... read more read the manuals, at that point it could not be returned. Just something to keep in mind if you are thinking about the GE product.

    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.

    Great product does what it says it will do
    Very happy with purchase wish I had done it 15 years ago could not get my husband to agree to it.. Runs like a gem has a little qlich had a bad fuse so it ran the battery down and would then not start the generator. But got that replaced and it runs just beautifully. The out side of the box is very pleasing to the eye.

    Easy to Install and Quiet running ! Good instructions and support !
    Runs very quiet when it runs once a week to exercise its self and charge battery.Programing was easier than I thought.I poured a concrete slab and dug the trench to my 500 gal propane tank. Pressure tested by my gas company and it fired right up. We did switch it from Natural gas to LPG. Great product for homeowners. It runs my well and whole house, It starts about 9 or 10 seconds after the power goes out. Great piece of mind for us in rural northern Ca.

    So far so good
    I hired an electrician to install the generator due to permit and inspection requirements. He chose to install with 100 amp service, which added some cost and time to doing the work, due to large wire size. Overall the installation was straight forward and everything went fine. I already had a breaker panel set up for a generator, so did not use Square D buss in transfer switch cabinet. Unit started immediately (Nat Gas) on the first try, and we gave it three more tries by manually killing the ... read more power company feed, and each time the unit started and transferred the load successfully. First outage will be the next test.

    This product is a very well made item.
    I am very proud to have this Kohler Generator sitting on my patio. It seems to be very well made and is in a corrosive housing. I think kohler is a little too pricey on their accesories. They ask $700.00 for the automatic switch and Generax has them for under $500.00. The problem, Generax is not compatible with Kohler. You can't win for loosing...Fred

    good product
    good product but the battery that I bought separately did not fit into the cover. Kohler should specify the type and size of battery required for each model.
