Works As Advertised
The generator came quick, real fast service. Haven't had to use it yet, but it starts up every other Wednesday and runs for 5 minutes. It was fairly easy to install and straight forward. We had to replace all the wires from the switch because of the distance and we also put a quick disconnect on the side of the house in case of an emergency. I was going to install it myself but, with the short wires and code putting it at least 6 feet from the building, I used an electrician that was... more
Pros: Price, Easy To Use, Features, I'd Buy It Again
Cons: Wires from switch not long enough

I Feel Bettery Having It
It came very quickly. It surprised me that it was here, in NH, in two days. The electrician says the manufacturers are much slower. Hooking it up went smooth and it started right up and supplied power upon testing it. I was a little bummed that I can't use the synthetic oil I have for other things because the manufacturer requires their oil only for warranty. I'll have to buy theirs. Haven't had a power outage yet, but probably will over the winter.
Pros: Price, High Quality, Durable

Should Be Well Worth It!
Just installed a 16kw Generac #6461. I did all the work myself except for the gas run from the meter to the unit. I am a retired electician, so it was a fairly straight forward installation. The gas line was done by a pro plumber.

The unit fired right up and the check out procedure was completed with no problems. I would recommend reading the instructions repeatedly ( 6 times or more) if you are going to do the work yourself. Should be well worth the time and money. Time will tell.
Pros: Features, Quiet, Price, High Quality
Cons: The Only Con Would Be Some Instructions Needed Clarifcation

I purchased a generator from Electric Generators Direct, and the people were very nice to deal with. They helped me by explaining how to set it up, and it was very easy. They also got me a cold weather kit. The generator and pack were delivered very quickly, and all was in good condition. Would deal with them any time will recommend to anybody that going to buy one also looking at other things they sell.

New Automatic Generator
It is just now installed and works. I now have peace of mind about any outage either when I am home or gone.

The cost was competitive and the device is endorsed by consumer report.

Generac Works First Time
The Generac arrived exactly as promised. The installation and wiring by the electricians went well and it all looks neat and tidy. We flipped off the main breakers and away goes the generator. At 12:00 am the first of the month the generator stared right up for 10 minutes and then shuts down. To this point I couldn't be happier. It would be nice to have some sort of indicator that tells you if the generator did go off while you were away.

Manufacturer Response
Brand Rep
Richard,
Thank you for your positive feedback. If you are interested in knowing whether or not your unit has operated while you are away from the unit, you have one of two options. First, the generator's control panel holds a History/Run Log, which can be accessed to identify the times at which the unit has operated. However, if you would like to access this information remotely, we would recommend considering our Mobile Link™ Remote Monitoring Device, which allows you to receive alerts on your phone, computer, or mobile device. To learn more about this particular accessory, please visit the following link: http://www.generac.com/all-products/parts-accessories/mobile-link . If there are any questions that we can answer for you, we can be reached 24/7 at 888-GENERAC (436-3722). Again, we thank you for your thoughtful submission.

I Have Two!
I have 2 now - a 17kw and a 16kw

If I did not like the first I would not have bought the 2nd one.

Had a 16kw generator installed and will probably never lose power again. Unit is all I thought it would be and gives me peace of mind.

Generac 16kw
Love the generator. It is quiet and very nice. I was very disappointed to look at the website today and see it was on sale for $400 less than what I paid and was told that I could not get that price though I received my generator 2 weeks ago. Other than that, very happy.
