A work horse for the Mid-West weather!!

After the several months of Severe Mid -West weather and constant power outages! We up graded our generator to the GP6500. It was very easy to set up as well as to use! The features that is nice to have on this unit were the large 7 1/2 gal gas tank, easy to pull start and power to supply my entire house!! This unit is not only great for home back up power but we also took it on our hunting trip and made the trip just a little more like home!

Nice Generator

This little GP6500 / CO sense technology performed perfectly for the 2 days we needed it much better than we expected.Easy assembly,oil fill and gas fill no issues. First pull started right up! Powered every circuit. Refrigerator,Freezer,Window AC,Cell Phones charged and several lights on keeping us safe,our food cool and frozen. Thank you Generac for making these units quickly available for purchase as needed to power up after a major storm left our area look like a war zone of downed trees,power lines and heavy property damage.

175 HRs , Running strong

Excellent reliability, use on job, always starting and stopping the generator.. Even dropped off of the side of a roof, and it landed up side down , still started first pull after this incident...I have replaced the pull cord once during my two years of ownership

bring on the hurricanes!

[This review was collected as part of a promotion.] Last year we ended up without power for well over a week due to Irma. This hurricane season I am so very thankful out family is covered with for power failure! This is a large generator but very portable and powerful! It's very easy to use and well built! I also can't wait to put it to use on an upcoming camping trip we have planned in the mountains!

Easy setup

It was very easy to setup and it started immediately. I bought this as a backup to use for sump pump and refrigeration. I feel Generac was the safest way to go because if reputation. I can feel at ease when we need it. The sticker with product info needs to be moved to make it easier to see.

Worried about buying a remanufactured generator.

I purchased this generator in late June after a bad storm and I lost power for almost a week. Vowing, that that would never happen again. Tyler tools had a remanufactured GP15000E on sell for under $2000.00 (great price), so I bought it. Had the house wired up, so I could run anything I wanted as long as I stayed under 50 amps. Did a test run under load and it was working great, I was very happy with the performance for about 7 minutes. Then, ka-pow, generator stopped. I tried starting it several times; it wouldn't even turn over, dead as a doornail. I took the generator to my local dealer (Precision Small Engines, Inc.), they told me the engine control module was fried and a new one would have to be ordered. It now runs, I have not retested it under load. I'm worried about a failure when I need it most. The other problem is the wheel kit. Not everyone has a garage and those that don't have to store it in the basement or tool shed, for me it was the basement. The wheel kit measured 31.5 inches wide and the door has an opening of 29 inches. I had to make other arrangements for storage. Only time will tell if this was a good purchase.

Has everything I need!

This is an excellent generator for the price. Starting with the person that took my order, he answered every question I had and it took no time at all to get it ordered with a delivery date that was met! Assembly was a snap. It took no time at all! I put 4x4's under the frame then installed the axle brackets and the axle. The tires were just a bit wider than the pallet, so once the tires were installed, all I did was roll the generator off the pallet! It started up easily and all plugs put out the voltage that was labeled! I took it to my deer camp and ran the cabin without a hitch! It is a slight bit noisy, but if I have a choice of noise or no electricity, I will take the noise any time!! I have not run my house with it yet, but that is coming up soon. Living on the gulf coast, you never know when a hurricane will come in on you and I will be prepared!! At this point, I give this generator an A++ rating! Once I run the house on it, I will give an update!

Life saver during power outage

We was dealing with a major power outage, after looking at several other brands, I went with this brand and size, because everything I have heard, I trusted it. This unit was perfect, it provided power for my side by side fridge, and two upright freezers with plenty to spare. While others were sitting in the dark, we was sitting in a well lit living room eating supper. Love my new Generac generator.

Very easy to setup and use.

Everything with this product met my expectations and functions were easy to use. However the only thing I have to complain about was the products packaging was perfect but the product was damaged inside the box. The fuel line nipple was broken at the back of the control valve and was leaking fuel. The problem was the fuel line was cut too short and pulling on plastic nipple.

Excellent Generator!!

This generator performed excellent right out of the box!! Took less than 20 minutes to assemble prior to starting. Very simple instruction for assembly and operation. Came in handy when we lost power recently for 7 days!!! Believe me, we put it through the tests to see just what it would and wouldn't run and were very surprised. The only thing it wouldn't run was our drier which was no big surprise. Ran all our other 220volt items!
