Excellent generator

I bought the GP7500E with electric start the night before storm Sandy hit NJ in 2012. I ran it 14-16h per day for 10 days without any issues. I did not follow any of the recommended maintenance such as oil change or drain the fuel tank when it was sitting outside for 5 years more or less unused. We then moved to CO and after getting off grid land in WY a decided to get it started. All fuel components except tank needed to be replaced including the carburetor. I replaced the spark plug and oil. After letting the carburetor get fuel for a few minutes it started on first pull! I replaced the battery and it start with just a short press on the start button. Only issue is the hour meter is now blank and shows to run hours. If the generator can take my misuse it can handle anything. I’m very pleased with it.

Generac GP 6500 series generator

This is a very good product, easy to put into use, and I can effectively use it to run everything I need in an emergency. starts easy even though it doesn't have an electric starter. I would by it again. We live in an area where storms take out power frequently. The transfer switch was easy to install as well.

Have not needed it yet

I received this item early last spring. I got it to be used in case of an extended power outage which is very rare for my service area. But since I have a grinder pump for my septic, I could have water from the local tower but wouldn't be able to flush without electricity. The unit was packaged and shipped very well. I finally unpacked and assembled it in late July. The assembly was very easy and the unit started on the second pull. I ran it for about a half hour but have not had to use it since. I did install an outside receptacle that I have wired into my main panel. So I'm ready. It is hard to give a review of something that you haven't had to use, but based on my observations as a mechanical design engineer, and from the Generac reputation, I have much confidence. When and if I actually use this generator, I update this review.

Very happy with product

Generator arrived very well packed. Initial setup was easy. Fired it up and put it on line with no problems. Very happy with product and feel I got a "good deal". If I were to make the product better I would give it a built in battery charger. The accessory style unit is okay, but is slightly inconvienient.

Easy to Start

[This review was collected as part of a promotion.] This is my 3rd Generac portable generator not because the other ones went bad, but because we use all 3 as a service provider. These always start easily and provide the power we need at the various locations were landed power is not available. Fuel consumption is not the best, but you sacrifice using fuel for the amount of power you actually need. So my recommendation is don't oversize your generator to much for what you actually need.

Outstanding Generator

I'm a generator mechanic by trade (military) and I know quality when I see it. I am very impressed with the attention to detail. From the oil drain line to the control panel battery charger to the extra large fuel tank. Every aspect of this generator is excellent, to include all the parts needed to perform the first scheduled oil change and maintenance. In that kit was also a funnel, towel, spark plugs, oil, oil filter, air filter, foam pre-filter, etc. The frame is extra heavy duty and looks as though it would take the worst of abuse. Some other noted features: spin-on oil filter, idle control switch, fuse protected control panel, a wide variety of fuse protected power outlets, extra large muffler, electric start, never-flat tires, and an incorporated lifting eye. The instructions were easy to read and initial setup took only 20 mins or so. After hooking up the battery (came 100% charged) and filling with oil, one short push of the start switch and it was up and running. Smooth idle and steady clean power top it all off. This is an outstanding generator and I can tell that people (engineers, designers, etc) put a lot of thought into its design. I definitely recommend this generator to anyone looking for reliable backup power and/or portable power.

Started Right Up & Reliable

I got this one to replace my older model Generac which needs service- 15 years old and still running well. This new one is just as reliable and started up right away the first time I used it. I use it weekly to pump well water and also use it for my house as a back up power source (off-grid). I researched for months before deciding on this generator and it has been everything that I needed and expected. Works great and I highly recommend it!

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

Great features

Love the CO sense no worries about the possibility of CO poisoning. The electronic push start lessens the hassle of pull start. Parts list could’ve been a little bit better detailed and the directions for installing the feet using the bolts and bolts for handle could be a little bit better but all in all everything was put together in about 15 minutes. I think instead of using cotter pins to secure the wheel pins I’d rather use a nylon locking nut.

Works just like is it supposed to.

Bought this almost a year ago, worked well, although I only had to use it the one time then. Power company trimmed all the trees over the lines last week, so I don't know if I will ever need it again. Glad to have the b/u though. I know it will work next time because it is a Generac
