Centurion 5536 Reviews & Ratings
So Far, So Good!
By Jeff
Fowler, Indiana
Review Posted 12/26/2011
We installed our new generator without much trouble. It took three tries to get it started on the initial start-up, which was partial due to air in the gas lines. Only real issue I had was getting the battery in the little opening they provided. Then trying to get it back out to readjust the battery cables. Otherwise I feel like the product is a fine asset to our home.

This Is The 3rd Generator I bought from EGD.

Review Posted 11/23/2011
I have had no problems with Electric Generators Direct. I'm an electrical contractor installing these generators, I can't get them fast enough from Generac directly, and when you count the shipping its pretty much the same price I can get them for from the factory. The factory sticks it to me on shipping, buts its free from EGD.
My only complaint is with the trucking company. They can't seem to comprehend the call 24 hours in advance written on the orders, or that I need a lift gate(which I paid extra for). This time had they called in advance I would have reminded them they needed a smaller truck with lift gate. When I met the trucker on the road, (blocking a lane of busy road) I see he had the shorter trailer and could easily have turned around on my road, like the previous R+L drivers had in the past. So be ready to either tell them to come back later with the correct truck, or be ready to deal with this. If I had told them come back later I would have had to post pone the installation planed.

Loving My Generator So Far!
By Carol
Chateaugay, New York
Review Posted 09/29/2010
I bought the 12kw generator for our home about 2 weeks ago and so far am very happy with the result.
The generator was installed and the very next night the power went out for about 4 hours. Well I didn't think I would get to use it so soon! The power went out and about 15 seconds later I heard the generator switch kick on!
I never had to get out of bed or anything!! I was so excited. Then the next time I woke up the power was back on and I didn't need to do a thing!!
We have wanted one of these generators for a long time because we do lose power a lot in the Adirondacks where we live.
Thanks Generators Direct!

One Of My Better Deals.
By Dennis
East Hampton, Connecticut
Review Posted 09/13/2010
Thanks for all of your help with the order, and the delivery of the generator, everything was what was promised. Electric Generators Direct made it easy to find the right size generator. My son and I did all of the hookup, and the transfer switch and generator were easy to install. The instructions were a lot of help.
This generator is replacing a manually operated 5KW. So far it works great. My wife is sooo happy that if I am not home when the power goes out, and I'm not there to take care of the old manual generator operation, this new 12KW Centurion will.

Please be sure to check your local zoning and insurance codes; some areas require a standby generator to be installed or certified by a licensed plumber and/or electrician.

Review Posted 08/29/2010
From the website to the order taking to the delivery to the generator itself, everything was what was promised.
The website really made it easy to find the right generator. I did everything myself and found the instructions to be a pretty good assistant.
The transfer switch and generator were easy to install. I think it took longer to figure out what circuits I wanted to have on the generator.
After everything was done the generator operated flawlessly, even under full load.
Bring on the storms! Thank you for great website and product and service!
