Quality, Portable Power!

[This review was collected as part of a promotion.] This thing is a beast- in the best way! Its quality and I love the rugged wheels it comes with making it portable. The best feature is the tri fuel. It’s great to have multiple options to power it. Worst part is how heavy it is and trying to get the wheels attached.

It was a life saver

[This review was collected as part of a promotion.] This came at just the time I needed it, we had a bad storm and lost power for a while, and i got a chance to us it! I'm impressed, it did it's job!! It was so easy to put together, the instructions were clear cut, and I'm overall impressed with it. If I had any qualms, i would say it's a little pricy for me, but I'm so very thankful I now have one. It's a good product and I would recommend.

excellent product

I purchased the GP17500E to replace a Generac 15KW/22.5KW generator that I purchased new over 15 years ago. It is noticeably quieter than my old unit ( which still functions perfectly and is now my emergency backup ). Being that we live in S. Florida, having a reliable generator is extremely important. I had numerous brand options, but chose to go with a brand that has served me flawlessly for over 15 years through many hurricane related extended power outages. When you really NEED a generator to work; you will be glad you purchased a quality brand like Generac. I now own 4 Generac units. Two GP3600's for running several small window AC units 24/7 and my big GP17500 and my older 15KW model. Due to limitations on fuel storage, we only run the big unit 4-5 hours a day.. the little units will keep us at a comfortable temperature all day and night powering the window AC units using much less fuel.

Power and reliability when you need it

This is my 2nd Generac generator and I purchased this one for home backup. I have found the Generac brand to be there when I needed it. My 5500 portable is great, but because I added a large shed, needed just a little more. Found them easy to start and maintain and are extremely reliable.

Very nice and works so well

[This review was collected as part of a promotion.] The photo shows it on its side because the wheels were being put on. However the wheels make it much easier to move around and the handle is even a better touch. The noise is not as loud as some I have heard and it was easy to start with the pull start. We plan to connect it to the house so it will run a few major appliances like the deep freezer and fridge.

Great Generator

Purchased the gp6500 after a lot of research. It offered the best power for the price. We only had to use it for a little over 1 hour for the first 7 months we owned it. We have been faithful in starting it about every other week or so and ran it with a load for about 20 minutes. We have kept the tank full of gas treated with stabilizer. Well sure enough we lost power this week do to freak March snowstorm. Started on the second pull. It ran over the course of three days for 29 hours. Worked flawlessly. Really a lifesaver, especially with three kids and the wife. Ran 3/4 of the entire house including a well pump, two refrigerators and a deep freezer. We have a Woodstove in the basement so no need for it to run a heat source. Bottom line... Awesome product, great value and so far seems durable. If you're debating this generator, go for it!!!!

Let me down during the storm

Helene came through, purchased this generator and it ran for less that 25 hours and wouldn't keep running. Took it to the local services center and had to pay $40 for them to evaluate it for repair. Makes me leery of investing in a whole home system through generac.

Leaking Gas - Brand New!

Selected the GP7500E above two other choices. Assembly was easy but, I was filling up the gas tank and the gas was leaking out the carb almost as fast as I was pouring it into the tank. Called customer service and found out this is a know problem! Now, instead of taking it to our cabin this weekend, I am taking it to a Generac Service Center. Very unhappy that it is leaking gas out the carb and it is a know problem! Maybe I will get a gift card for all my problems.......but......I don't think so!

Great Generator if you can get it started and keep it going.

One reason I purchased this generator was for the ease of starting it with the electric starter when the power goes out. The first week I had it, it started right up, but once I removed the trickle charger that came with it for a couple days it wouldn't start. I figured it had a bad battery or a short in the system, so I took it to a Generac authorized repair shop to have it checked out and they said the battery was bad and replaced it. Sad to say the new battery was also dead after sitting a couple of days. I did some research on the internet and discovered that this Generac Model had issues of shorting out and causing the battery to drain and die. I installed an on/off toggle switch to isolate the battery when not in use and that fixed the shorting out issue. One other issue that I've ran into, is that this CO sensor is almost too sensitive, if the wind blows the exhaust back towards the generators CO sensor it will shut down unexpectedly, so I have to position the exhaust pipe towards the same direction as the wind is blowing. Now that I know what it takes to get this generator started and keep it going it's actually a really good generator and it performs well, it's just not user friendly.
