The GP17500E is an excellent value.

This unit has more features than I expected ie: winter carb heating and an excellent variety of electrical connections that suit any purpose. I will be using it for a solar power system back-up. I have previously purchased a standby Generac (16kw) for our home and have been more than satisfied with it as well.

Very Satisfied

After returning the original purchase due to a defect, the replacement generator went together quickly and easily. I was concerned about previous reviews that talked about difficulty putting oil in and putting the wheels on, but I had no problems. You do need a funnel to add oil, but a funnel with a long neck worked fine. After the unit was assembled, I put some fuel in it and it fired right up. I also put a small load on it to ensure it was actually working. All in all, I'm happy and confident this unit will perform as expected when it is needed.

Great generator overall

Uncrating was simple, as was setting it up. No missing parts. Followed setup directions which were fairly easy. Added oil and gas. Turned fuel lever on and pressed the start button and it started right up and ran great! Would highly reccomend this generator. You will not be dissapointed! Let the power go out. I am prepared! Thanks generac!

superior product

A power loss at our daughter's home led to our purchasing this product which was of such superior quality to the "store" brand as to make this an easy decision. Quick and relatively easy set up (one balky nut/bolt) got her the power she needed to save a freezer of food. This product is sturdy, solid and easy to start.

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.

Great generator

I love the generator. It works excellent, just as expected. Starts immediately and runs well; provides the power I need when required. The only complaint I have is the noise level when running. Surely Generac could or should have equipped the generator with a muffler system to quieten the sound emitted.

This generator has about average features

I purchased this generator as a back up for my home, and used it only 5 hrs and I haven't found it to be any better or worse to setup or features it offers. It is not as quiet as I had hoped. I have owned or own 6 generators. Size of those units have ranged from 2000w-15,000watts. The gas cap was very difficult to remove to fill with gas. Attaching the battery cables was not easy at all and I have some mechanical ability. Battery location could be better. Oil that comes with the unit does not give a 30W, 10W-30 label and does not indicate the size of the container, 32oz, 24oz, 42oz.. I did enjoy the ease of transporting it from the house where I assembled it to the shed in several inches of snow, where it is stored. That distance is 125 ft. The Generac brand has been around for years so I hope to get 1000 hrs + of use with no mechanical service issues.

Just when you need it . . . !

My wife and I live in a very rural, small town in Middle Tennessee, and, as the nature of the beast when you live in a setting such as this, we often lose power. We have been "thinking" about getting a generator for some time now because we often have ice storms during the winter that can knock out our power for several days at a time. However . . . It was a recent wind storm that finally "pushed us over the edge", and we took the plunge and purchased our Generac 8000E. Our entire county sustained major damage to the electric infrastructure due to 40 to 60 mile per hour winds, knocking out some peoples power for as much as two weeks. When I went to a local Generac distributor, the staff asked me questions about what I would want to power in my home, and if I wanted a generator that would be easier for me to use. Looking at the three models they had on display, my wife and I decided to get their 8000E, and we were not disappointed. It took us about 45 minutes to set it up, put in the oil and gas, check it out, and when I hit the start button it cranked right up with no problems. Right out of the box, we ran that thing for three days, providing power for two refrigerators, a freezer, lights, and even our TV and DVD player. Not to mention we were able to charge up our laptops and cell phones, too. It was a purchase that was a long time in coming, but it was well, well worth it!

Can't wait for a power outage now!!

As a homeowner, I am thrilled to have the generac generator. It was really easy to set up and it starts so easily with the electric start. Having a quiet muffler was also important to me. It' a convenient size to store in my garage and pull outside as needed to use.

Impressive power and feature!

[This review was collected as part of a promotion.] Worth every cent!! Top of the line!!! This is absolutely an amazing generator—-I mean, top of the line brand, and just remarkable specs. It can run on gasoline, liquid propane, or natural gas. It offers 12500 starting watts of power and 9500 running watts. This generator gives me so much comfort that if something happens, I know we will have power and everything will okay until the power comes back! It can run from 3 fuel sources which makes it convenient for many emergencies or when you need it most. The wattage and power is impressive. I highly recommend this generator— worth every single penny!!
