Not the quality produced I expected

I purchased my Generac generator right after the hurricane and initially it worked fine. After a day or so the 120V electrical panel started malfunctioning - the Ground Fault breaker kept tripping under load. Then it wouldn't reset at all. I had to source a four prong plug from Illinois to use the other electrical panel and that took days to get here. So, I had to go purchase a second generator - not a Generac. After normal household power returned, I took the Generac to a repair shop where it sat for four months waiting on parts. Overall, I don't think I would recommend a Generac to anyone. Poor quality and even worse warranty service. Now I have an $800 paper weight.

Feeling good about having a good generator

Purchased the unit in the morning and had it fully loaded up and operating that afternoon. It handled 6kw of electric heat without any issue which would be the maximum load I would expect to have on this generator in winter conditions. I have a generator panel so have the ability to switch load as I need it including heat, water pump,refrigerator, freezer etc. While I'm not looking forward to the next major power outage I do feel much more prepared for that event.

good quality machine and good price

Just got generator today, it is replacing an older, smaller one of another brand. Put it together with no problems and it cranked right up and ran smooth. This will be for occasional use as a home backup generator. Looking forward to many years of service from it.

Worked PERFECTLY, as expected!!

Last night was the "maiden voyage" of my new 8000 Watt generator, as we lost power from the explosion of a local transformer from heat related power overload. GENERAC to the rescue...it took all of 10 minutes to roll the generator out of the garage, hook up the power cable, start the machine, flip the transfer switch and back to the comfort of lights, TV and A/C, etc. While my old 3500 WATT generator performed well for the past 12 years, A/C was not an option, nor was using the microwave and other applicances. My new GENERAC machine performed flawlessly with gasoline consumption and noise both being reasonable. Bought it directly from GENERAC; the process and delivery were convenient and easy. I recommended this unit to my next door neighbor last night and he bought one this morning, and I would recommend GENERAC to everybody. Great product and great customer service (sales and delivery).

glad to have this

Good product, easy set up and install. Live in rural area and power sometimes goes out for a while, so always wanted this. Looking for an enclosure to buy so I can store it closer to outlet, not sure how it will pull through snow from garage. Started on first pull, hope it's always that easy to start.

Great generator

This is my first generator, but we moved to a rural area where the power goes out regularly so we needed an backup generator. I was thrilled to be able to find a portable generator this size, because we can't afford a standby generator. I was so impressed with this generator when it arrived. It was so easy to set up and came with an extra air filter, oil filter, and so on. Very nice tough. I feel much better know we'll have heat and water if we lose power this winter!

Excellent layout and presentation of features

I love my new Generac generator. It is exactly what I wanted and my wife bought it for me for Christmas. Great features and great performance. I considered other products, but none had all that I was looking for except the 17500E. So I wasn't going to settle for almost .... bought the best and got everything I wanted !!

Good quality machine, runs great.

Assembly was easy and straight forward. Serviced it with gas & oil and connected the battery. Opened the fuel valve and hit the start button. It started on the first crank. Ckecking the outlets with a meter I noticed it ran quiter than I expected. Everything was right on the money. Too bad I didn't own it in time for the 2013 Christmas ice storm. I was a contruction tradesmen for forty years. I know and appreciate using quality tools.

Just runs and runs

I'm no Nor Cal and have been experiencing the PG&E Power Safety Shutoff. My neighbor had one of these 8000's and I was fortunate enough to find one as well. Electrician came and wired it into my panel and wow...my whole house just runs like it's on PG&E. Some little weird stuff to get used to, like when the well kicks on, the LED lights in the kitchen flicker for a second but no big deal. Hot showers (propane hot water heater), lights, etc. I go into a room and turn on the light...just like normal. Only complaint is it's loud so getting it away from the house is important but we just close up the windows and deal with a bit of a hum to have power.
