Great generator with a couple of minor discrepancies.

I bought this mainly for sudden power outages that I have in my area. Considering the fact that they happen often and living out in the country. Also being on well water. Back up power of some kind is even more important. Of course beggars can’t be choosers and didn’t have much of a choice but to pick this one at the time. I am however still very happy with my purchase and will do 90% of what I need it to do. Start up, running and shut off couldn’t be much easier and like that it can still be pull started if necessary. The charging port for the battery is a nice touch too. Negatives: The instructions weren’t hard to follow but were hard to read because everything was so small. The lettering and pictures. Only other small issue I had was with putting on one of the wheels. The spindle as I guess you would call it where the cotter pin goes into had to be inserted the opposite direction of the other one because the motor mount is in the way. That’s something that could easily be remedied at the factory but would’ve been nice to see that in the instruction manual at least because I had to second and triple check to make sure I wasn’t doing something wrong. Yes I’m aware it does not affect the generator at all whatsoever. Motor or moving wise obviously. Only thing I wish this generator had was a smart idle. In the future if and when I do get a power outage I know for a fact that this will do what I need it to do and still recommend it to people. If this 8,000 watts is enough for said purpose.

Great product

We used this generator less than 50- hours. When we needed it again summer of 2020 we discovered the generator burned!!! Very DISAPPOINTED We had to use an older 10- year old Briggs and Stratton that started up right away. We are currently waiting on new generator to be ordered and delivered , due to Covid reasons it’s taken this long. We pray once a new generator is installed it will work great for us for years to come.

Home Back Up GP17500

Purchased for hurricane back up power for my all-electric home. Works very well but just falls short of being able to operate all the house loads. Having said that it still covers the important items (a/c, lights, tv, fans, etc.) but adding the water heater and stove pushes the 50-amp capacity. Neighbors are looking at upgrading their units.

I was very pleased with this product

The unpacking and assembly were well described and easy to complete with minimal mechanical skills. The engine started right up and power was immediately produced. I let the unit run for a few minutes and then checked the oil level and examined the unit for any leaks or other obvious issues but none were found. I would recommend this product to anyone in need of a large portable generator for emergency or other short term uses.

Absolutely worth it

I bought this generator a year ago after living thru other storms with no power. I never used it until the past two weeks with Hurricane Sandy here in NJ. Flawless performance. My friends and neighbors struggled with smaller generators ... the GP17500 ran without a hitch for hundreds of hours nonstop. Well worth it, not only for comfort and convenience of running everything in the home, but also for the for peace of mind that I wasn't under-powered or getting up in the middle of the night to refill the gas. Glad I got a portable ... when my power was restored I was able to let a friend borrow it.

Great Product

So I heard Generac has a great reputation for making reliable generators and even though I bought a portable generator, working in the propane business, their are many where I live that are buying the permanent home stand by propane powered generators and they are reliable and even though my is portable but used for home standby too, its what I want. I know it will do the job and keep us comfortable and our keep our food fresh while the power is out. I have yet to get my electrical panel up to code and a transfer switch installed on my house, but when I do I will be able to enjoy the full luxuries of having power without power :) Noise level though its just like a lawn mower or any other gas powered engine, pretty noisy, but again, your inside and its outside and so i can handle the noise.

Like all the features it offers

Had a hurricane coming our way so decided to purchase a generac because of its reputation. Set it all up and tested it out, but never used it because the storm turned and headed up the coast. We at least have comfort knowing we are covered if another storm heads our way, which is likely because we live in Florida.

Powerful

[This review was collected as part of a promotion.] What a powerful generator, it packs a lot of punch!! Great features like the electrical outlets, the size is compact and convenient and is actually a bit more quiet then I expected (it's not quiet, but definitely not the loudest I have heard) I think everyone would should have something like this for emergency purposes and recreational use. I would absolutely recommend this to all my friends and family.

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.
