    Kohler whole house generator/14KW
    The power has not been off yet.I think it will be nice to not have to hook up a generator to have electric power.

    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.

    Installed 4 years ago and works very well
    I live in a bedroom community north of Boston. Its been 4 years since installation and very few problems have occurred. I have it operating on natural gas which is the best option since it is less likely to be effected by stormy weather. The transfer switch works flawlessly. I hardly know when it switches from utility power to generator and back. is relatively quiet since I have installed it out back about 6 feet away from the house. The exercise cycle also works well and only a few minor faults ... read more have occurred. These were readily corrected with the help of your excellent phone support. It's also interesting to note that since I have installed this unit, we have not had a power failure for more than a few minutes at a time, so I don't know how well it will perform over an extended period.

    Happy with Generator
    Works well, needed warrantee work after one year which is very costly. Defective ground on engine generator and defective control board in electrical control panel. Dealer honored the engine repair, not the panel. Very expense and not a DY project.

    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.

    nice unit , quiet,poor manual
    the unit is very good looking and is very well made, it is very quiet when it operates and is easy to program, the installation manual is very misleading unless you have installed several, more parts are included if prewired and never know if its need or not as you proceed. still a excellent unit

    Great product! Easy to install
    After review numerous options I settled for the Generac 16kw. Great product and well built! Made in the USA! It was very easy to install and just as easy to use. Operation is effortless! Basically it's off, manual, or Auto operation! Well thought out for oil changes and maintenance!

    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.

    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.

    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.

    New Coustomer
    I've just bought this unit from Home Depot and have yet to get it installed. Still working on that. Just want to say to others that an instalation done right may run you as much as the unit itself. My bidders have said we may have to update my service pannel. Ouch. Thats about a grand on top of everything else. No matter as lone as it's permited, city inspected and tested I'll be happy. What Home Depot doesnt tell you ( I had to speak with Generac coustomer service) is that a "GenPad" is ... read more included in the kit. Along with a flex gas hose and transfer switch. I was looking to buy one and couldnt find it any where. Your best bet if you have questions about the systems is to contact Generac. 1-888-436-3722 I plan on witeing another review when it's installed and working. I'm sure I'll be happy.

    peace of mind in the middle of nowhere
    Delivery of the unit was accomplished in the most professional manner possible. My location in the middle of Michigan's U.P. forest land was of some concern to me, but the private delivery company used by Home Depot did its job perfectly. When I contacted Home Depot's customer service on several occasions to express some concerns about the delivery methods, the reps were always courteous and very helpful. The generator arrived in perfect condition and on time. Two days after its installation, ... read more there was a three-hour power outage, and the unit performed flawlessly. It is a state-of-the-art unit and offers peace of mind in such a remote location, one which usually experiences frequent power outages throughout the year. Because my house is all electric (including heat), this type of protection is most welcome!

    This was a great deal from Home Depot!
    This is an upgrade generator. I am replacing 12 year old Briggs and Stratton 12 KW. This 22 KW will handle my whole house. I'm hoping I won't need it, but if the power goes out I'm ready. Very nice!

    Works as advertised.
    Product arrived on time and in perfect condition. Electrician who installed it was very impressed with how easy it was to install with it's pre-wired transfer switch. Unit started right up and performed all tests flawlessly. Initial excercise of generator also ran properly. 10k generator supplies my small home with almost complete electrical service. No more worries about power outages.

    Great Generator - be selective with who installs it
    I do a lot of research before I buy things, this generator seems to be the best value out there. My only issues were the installation charges. Home Depot contractors quoted me $7500 installed - that's $4500 just for installation of a $3000 generator??? Back to researching online - I found a website that stated the installation should take about 6-8 hours for an experienced electrician. Ok, so I called some other Generac dealers in my area. They were all around $3000-$3500 for installation. The ... read more n I called just a regular licensed electrician, said he's installed several Generac generators and he'd do it for time and materials, should be about $1000. It took him about 7 hours total, my bill came to $810. The propane company charged $550 to install 2 100 gallon tanks and hook them up to the generator. So total installation cost for me was under $1400 - a far cry from $4500 - do your homework, make some phone calls. We don't lose power often, but it's peace of mind knowing we now have this unit hooked up.

    Good price, acceptable quality
    I am electrician and we have installed more than 100 in less than a year, I like the performance, virtually dot have to do anything, just change the oil. It is true that we have taken some mechanical problems with some, but in general I like. I recommend it.

    My GE Stand By Power
    I had to replace a damaged 14 year old stand-by power unit with the General Electric 20KW generator. I chose GE over Generac and Kohler because of GE Symphony II power management, internal engine heater, and running DB rating. In addition, certified installation company was of "paramount" importance. Scott and Keith at Emergency Power Solutions, performed a excellent quality installation, have excellent GE product knowledge, and prompt monitoring and communications during power outages. This was ... read more a excellent investment for the safety of my family. Works wonderful !

    A very useful addition to our property
    We have a handicap situation in our home and need a back up electrical source to operate the assistance equipment our daughter must live with. We did run into engine problems early on but were addressed quickly and none since. The unit was installed in the Fall of 2010 and currently has 250 plus hours of service (New Hampshire location). The switch over to the generator and back to the electrical grid is rapid and smooth. I have constructed a roof over the unit to keep the snow buildup away from ... read more the air intakes, saved shoveling.

    Remains to be seen
    This GE generator is a branded Briggs & Stratton unit with a better warranty. All customer support, technical support & warranty is done thru them, with GE providing none. That said, I have no problems with that. My issue is when purchasing from the Depot as they are not a listed service or warranty provider for this GE unit, it is up to you to find a dealer when required. Installation was pretty straight forward, with me hiring a licensed plumber and electrician as required. So far we haven't ... read more had an outage so it just sits there....waiting. How well it will work, I have no idea but I'm hopeful as it tests fine. It has a 5 year parts & labor warranty on the generator side, 2 year on the motor. That is longer than most. Again....I'm not sure who will handle this as all the Briggs & Stratton dealers are independent and let's face it, they handle there own installations first. This generator also has load shedding modules for extra cost which are optional & so far I have not had them installed. In short, I'm not sorry that I acted as the contractor, because I saved some $$, but next time I would hire someone from GE's list of authorized service dealer network to do a complete job.

    Excellent value
    The Kohler 14SESAL was delivered in 8 days. The truck driver was very helpful in moving the generator toward my pad. I am more than satisfied with the whole transaction.

    Not the cheapest but probably the best overall system
    The system is just as promised in the literature. It is more than a temporary solution to emergency power: it is designed to be installed permanently. The transfer switch is a real bonus and not always part of a generator package. Installation is possible as a DIY project but it may be wise to call in an electrician for the connection of the transfer switch to the home electrical panel. The system ran perfectly on the first try and the automatic test feature will do weekly runs to ensure that it ... read more is ready when needed. The only missing feature is some sort of remote monitor/start control so that the status can be checked without going outside. Kohler makes a "ACD remote" but they are difficult to locate.

    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
