hard to move

I give this 17500E a 5 star rating. The only con I have is the portability. I have to move the gen. around. I mounted a heavy duty caster with brake the second day I owned it , this totally changed the portability, I can move it around with one hand. Also I believe the handle needs to be adjustable so you don't have to do a shoulder lift to get it rolling.

This product runs great and has great safety features

Recently we went through a 90 hours power outage and this generator combined with the Generlink transfer switch got us though this outage with minimal inconvenience. Only had to use this generator a few times since i purchased it two year ago but it has been a life saver

Good product, easy to set up and use but heavy and hard to move on any incline.

My generator arrived quickly as was easy to put together. It has worked well and more than met our needs. However, it is very heavy and hard to move. Our driveway has a slight incline to it. The weight plus the small tires, which are tubeless and hard to keep inflated or replace, makes it almost impossible for my wife to move out of the garage to use. Also, be sure you keep your battery charged. That said, I'd buy another one.

GP8000E

I bought this generator after my old one (not a Generac) quit. I always shut off the fuel and let the carburetor run out of fuel. I also use Seafoam in the gas. This helps to stabilize the fuel and keeps the jets clean. I purchased a product called Generlink that fits behind my electric meter and allows me to plug the generator directly into the meter. I also use a solar power battery tender to keep the battery charged. I am very happy with how this generator performs.

I recommend this product

The generator is easy to use and to move around. The portability makes it useful in a number of different situations. The generator is a bit noisier than I would like, however, the convenience and ease of use out weighs this distraction. Should we experience another hurricane, we will be quite comfortable and safe. We plan to have this wired into our system so that our whole house will have power in the event of an extended outage.

Ready for storm

After losing a fridge full of food, we bought a Generac inverter generator. Gp 2200. Ran a few hours break in then switched to synthetic 5w-30 for much better protection from high temps. Can run sump pump, fridge, freezer, washer and gas dryer. Obviously.not all at the same time, used watt meter and two at a time should be ok. Fairly quiet, starts easy, run dry after use. Turn carburetor screw with small hose on it to drain carb bowl. Most important, run ethanol free gas and add stabilizer!

Best I've seen

I hope I never have to use it, but if and when I do it's nice knowing I am relying on the best.
