Finally was able to use my GP17500e

I purchased this generator new approximately 5 years ago. I left an initial impression review at that time. Other than monthly test runs, I have not had to use it. Last night it was finally used to provide power for the entire house. It worked flawlessly. It was 28 degF. When I started the generator and it ran continuously for 16 hours with no shutdown. Temps got to a low of 6 degF. It’s one thing to lose power in the summer. Losing power when it is in the single digits is an altogether different scenario. Our house has baseboard electric heat that had to work in some rooms not heated by the woodstove. In conclusion, and as a follow up,after five years it did exactly what is what purchased for.

Purchased in the Nick-Of-Time !

I worked hard to find a full service dealer and settled on FD-Hayes, Lansing MI and was extremely pleased with their recommendations for this unit, installation and training. I had this installed on a Monday and literally that Thursday we lost power for 4 days and this unit performed admirably. The safety-switch mechanism on the breaker box was foolproof and the electric start was a real help. I ran it about 24 hours on a single tank of gas, it saved my frozen foods and kept my fridges at temp. I didnt use AC and that is not really a problem as I knew going in that AC would not be viable with this unit.

Great item to own!

[This review was collected as part of a promotion.] Absolutely love this product, and I feel better knowing we have a generator for backup now! Was delivered in a timely manner and was in perfect condition. Easy to start. Doesn't weigh too much... it's supposed to be portable. My husband can definitely move it around. Just plug you items in and your good to go! Looks pretty cool too... Love it!

Great product

I have had the pleasure of not having to use my generator that I purchased just over a year ago. However for the first time this summer it was finally used but yet again not by me. During a series of severe weather outbreak a friend of mine last power due to downed trees. I offer my generator to him to help keep his basement from flooding. His intention were just to use it for the sump pump. He ended up running not only the pump, but his freezers, refrigerator, air conditioning units and other things. He used it for 40 hours straight and forgot he was even on a generator until he had to fill it after the first 27 hours of run time.

Excellent Generator-Generac GP6500

Bought this Generator used with 100 hours in it (4 days of use) got a great price and looks and works like new! I can run everything in house, all lights, electric stove (not oven), heat (furnace) & hot water heater. Haven't tried to run the central air unit yet but the heat and hot water is more important, anyway I ran everything with no hesitation or strain on generator. I gave it a 4 on features because I wish it had a voltage meter on it otherwise all 5's! Full tank of gas you should get 8+hours run time with everything I described above, I Love this Generator and now ready for any outage, may not need for 3 years but will be ready when it happens.

Lifesaver

I bought this generator in 2020 while it was on sale at H.D. it sat in my garage until the Texas deep freeze that just passed, thank GOD that I had it, I was able to easily start it and power my essentials in my house, had it not been for the generator it would have been a very chilly and desperate time. I encourage everyone to have a home generator for power outages, it will save your life, thanks to Generac for making a reliable and safe product.

Great and reliable product to purchase.

2 of my friends, my sister and I brought the GP6500 Generator 2 days after Hurricane Helene hit our hometown in Georgia September 2024. I assisted 1 of my friend with the assembly process and I assembled both mine and my sister's generator by myself. It was a simple process. Once gas was added to the fuel tank, all of them cranked up on the first pull and stayed running until they either ran out of gas or was turned off manually. The generators was a life saver. They supplied power to what we needed and never failed to perform perfectly. They were used for 6 days before the utility company was able to provide us electricity again. I am now in the process of trying to get a manual transfer switch and power inlet box installed so that I can be more prepared for the next power outage. Thanks Generac.

Unreliable Generator

Owned it 2 years. Refused to start on one of regular start up dates. Took to small engine repair. He got it started after changing spark plugs. Got it home and battery was dead. Refuses to start. Can't count on it when we have a power outage. Waste of money. Now having to look at getting a Honda.

Awesome looking machine!

I just received my Generac GP8000E portable generator a couple of days ago. I bought it for the sole purpose of having back-up power in case of a power outage. I asked our electricians at work which generator they would recommend and they both said this one at the same time. That tells me a lot. We have a Generac stand alone at work that powers our whole office and I feel that if they both recommended this model and brand, then it must be the one I'll be happy with. I'm almost hoping the power goes off this winter..... lol

From delivery to operation the instructions are very easy to follow and assembly went quickly. Generator is very easy to operate

I have already put the generator to use and it works like a champ. No bogging down even under high AMP. Very impressed, really not as noisy as I feared, and the easy on off makes operating it a breeze. Very low fuel consumption which made it even better for the overall cost. I have looked into service the generator myself and this should be just as easy. Overall best generator I have come across
