Already had to use twice

I wanted to add a generator after how cold this winter has and fearing not having heat for my two small children. However, I have had to use it already twice this summer, and it has started up each time. I have even had some neighbors come over during the storms so they could make their kids comfortable as well.

Very disappointed

I have owned this generator approximately five years, it only has 60 hrs on it. It has been in auth shop twice and has had four new fuel pumps. Also new voltage regulator It has now blown the fuse behind the control panel and blows another as soon as installed?? I seldom post negative comments on products. In fact this is my first!!!! Very disappointed!!!

I love this awesome product

[This review was collected as part of a promotion.] I received this awesome generator to review. It's the best . The product it's self is great . Looks good and works well. Its well made and heavy, but once the wheels are on its super easy to wheel around and easy to use . This is something every household should have, definitely would recommend it.

Has yet to crank

Spent a lot of money on this generator and it won’t even crank. Not every generac dealer works on portable units, so took research, time and extra calls to find a dealer that would come out. The repair company has replaced the starter, the carburetor, magnetos, the list goes on yet it STILL WONT CRANK. This is extreme frustrating for the money spent.

Caught fire. Been waiting several months for warranty repair

After only 75 hours of operation, my generator control panel caught fire at the 230VAC outlet. I took it to an authorized service center in September, where I was told it would be covered under the warranty. It is January and I am still waiting for the repair to be completed. Otherwise it is a great generator. I bought 2 more, 1 for each of my 2 sons. I just wish the warranty service was more timely.

It powered the home for 7 1/2 Days

I bought this generator to power the home during those temporary power outages due to thunder storms. Then Hurricane IAN devastated our part of SW Florida. It was September 30, and I couldn't even go outside to set up and start the generator until 11 PM, when the winds dropped to 50 MPH. I bought the General GP-17500 to make sure, "IF", I ever ran the generator for a couple of days, it would have power capacity to spare. This generator powered the entire home for 7 1/2 days. I shut it down during the afternoon to cool it off, check the oil, and fuel it up for the overnight operation. And yes, I changed the oil and oil filter two times within the 7 1/2 days. Me being me, I even placed/positioned two floor fans to move air across the unit to ensure full cooling of the engine and generator. Like in tornado areas, once IAN caused its damage, the weather in SWFL was incredibility perfect. Low humidity, Low Dew-point, cooler than normal hovering around 75 all day, and cooler at night, for the next 12 days. I had wired this generator to back feed the electrical panel though a mechanical interlock and a 50 amp breaker. The main breaker must be moved to the off position, then the mechanical interlock plate is moved up, allowing the 50 amp breaker to be turned on. And when we needed hot water, we would turn off the home AC, then switch on the electric hot water heater for about 45 minutes, then the hot water heater was switched off again. We did not want to test the full power capacity of the generator, but it powered the two home AC units, the well pump, and when needed, the clothes washer and electric clothes dryer. Here too, we always powered down other high current devices like the AC units, and hot water heater, when washing and drying our clothes. For a "portable generator" bought to power the home for a few hours when a thunderstorm and winds temporarily knocked out the local power company feed, this generator performed well beyond expectations. Our next purchase will be a Generac backup Home standby generator. We now want this style unit so when there is a power disruption, the generator will taker over automatically, and I don't need to send my wife outside with the flashlight, instructions on how to position, connect and start up this unit. (Yea, listen to my big talk here. I do all of this, moving, connection and starting, but now see the wisdom of a built in home standby generator, since we recently moved to SW Florida I will start by getting a propane tank sunk into the ground, our HOA rules require this, and once in, we'll order the Generac unit with transfer switch. And "NO" we will keep the portable generator for a bit as a portable back-up generator to next to be installed backup home generator. I figured it was time to give feedback to those still on the fence.

Saved by Generac 17,000 Watt generator

Bought the biggest of all, the 17,000 Watt generator some years ago, and never used it until now. Living in Florida, you never know, when you need it, and now with Hurricane Irma, we lost power for several days. Backfeed my house at the panel, and supplied power to all my A/C untis (3 unit total) exterior lighting, etc, since we were the only house among 90 inour neighborhood, with full power, A/C, lights, etc. Unit started right away, and ran for 5 days 24/7. Highly recommendended. Only wish, you could have propane option at the flip of a switch, just in case. All gas stations ran out of fuel, so it would be a nice optional feature.

GP17500E

Generator does a great job. I owned one for many many years. I live in the country.We have very hard winters and that means power outages. The outages usually last many many hours.The Generac 17500 provides me peace of mind in a power outage. I don't have too worry about frozen pipes, heat, lights or food going too waste. I wouldn't be without my Generac. My original 17500 is getting old and this new one is the replacement/backup.

$$ Best Bang For The Buck $$

Having done extensive online reviews and talked to several folks that own similar sized portable generators I confidently made the decision to buy the Generac 8500E. I ordered online, it arrived much sooner than expected and after the installation checkout it started the first flip of the switch! Buyers can trust this generator to meet their critical needs, I certainly know I do!

Great product right out of the box!

I recently purchased two GP8000E CO2 sensing Generac, one for my house and one for my Mom. Easy to put together, start, and store! They start right up and are surprisingly fuel efficient. My Mom is 71 and has no trouble starting and operating the generator! We have used it several times since June and have been very pleased!
