Rated 4.9 out of 5 by 93 reviewers.
Rated 5 out of 5 by 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. December 24, 2013
Rated 4 out of 5 by Generator The ordering process and installation of this generator went smoothly. The only concerns I have are: 1. Piping running from the power source to the generator is huge. 2. The fact that it sounds like a tractor. October 23, 2014
Rated 5 out of 5 by 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 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. February 14, 2013
Rated 4 out of 5 by Exspensive I don't have it completely hooked up yet, as there is a lot that needs to be done before you can use it. I recommend that when you buy one of these generators, you also buy an installation package from Home Depot People. You will need a plumber to install the gas lines, then you will need an electrician to wire it in and also a permit. These are all things that you need to have done, but almost double the price of the unit. I have yet to use mine yet, but it is well built and a very heavy unit. If it works like they say, I will be very happy even with the added costs. Ron Gaydosh Harrison, Michigan. May 20, 2014
Rated 5 out of 5 by 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 (during my demonstrations) were amazed. A must have investment against aging infrastructure and more frequent and severe storms. November 1, 2012
