GREAT BUY!

I'm a dealer/ electrician in Massachusetts and honestly have had no problems with any of the (10) 6500w/e that i have received in the last few months. They are easy to assemble, start easily and with the large capacity tanks, they run all day long. I also like the free battery charger and built in jack. Great product!

Great Back-up Generator for Medium size house

I, too, bought this generator in response to a long term loss of power during Hurricane Irene. After spending so much money for a couple of days on dry ice for the refrigerator/freezer, I realized I could spend the same money on gasoline for a generator and have the additional benefit of lights and television, and not to mention being ready for future power losses. The generator was very easy to set up and it started right up with its electric starter. I ran the refrigerator, television, numerous lights, and the washing machine. It has enough power to run the critical circuits in the house and I plan to have an Auto-transfer switch installed in the near future. With some judicious planning, I think I can even start/run the smaller of the two air conditioners serving our house for short periods of time. Complaints (so to speak) - I wish it came with a ground wire for use. For safety reasons, the NEC requires the generator to be properly grounded but I imagine many people ignore this because they are only running the generator for a "short" time. Including a ground wire could serve to place extra emphasis on the safety requirement. Also, I wish Generac was more helpful with information regarding sheltering the generator during operations in inclement weather, and information on noise abatement. I imagine it is mainly due to legal liability concerns, but there are some responsible grown-ups out here using the generator.

Tri fuel generator

[This review was collected as part of a promotion.] This generator is perfect, nice heavy duty with the ability to run gasoline, liquid propane or natural gas fuel source. It is easy to switch between settings. It is heavy but with the wheels is portable and easy to move. It definitely makes noise, but to be expected with the size of generator and it’s tolerable. Perfect for emergency/power outages, job sites/ tools and camping. Well worth the investment if looking for generator, especially with the tri fuel option!!

Product assembles easily and generator started on first cord pull, but then...

I have rated the quality of this generator only "Fair" (a little below average) because of the two items that follow. The GP3600 generator is easy to assemble and it started on the first pull of the recoil cord. However, I ran into problems when I plugged in an electrical device: There was no power from any of the four 120 VAC, 20 amp, duplex receptacles (note: these receptacles have their own 20 amp circuit breakers). I had to call the store I bought it from and speak to someone who knows the generator and troubleshoot it with him. The problem was that the circuit breaker next to the single, circular 120 VAC, 30 amp receptacle needed to be moved from the "OFF" to the "ON" position. Once I flipped that switch there was power to all outlets. I did not know, and unless I missed it, there was nothing in the manual stating that the 30 Amp breaker controlled power to ALL outlets. There was nothing in the manual's startup procedure about this 30 amp breaker needing to be switched to "ON" so that power would flow to ALL outlets. I would recommend such a basic necessary item be addressed clearly in the manual. One other minor item: The plastic, zip-loc-type bags that the manual and warranty came in were very light grade plastic. I usually store the manuals for all of my power tools in the zip-loc-type bags they come in right in my shop near the tools themselves. So it would be nice if the bags were a little heavier grade plastic.

Awesome

[This review was collected as part of a promotion.] This was initially for hurricane purposes but I have a feeling it will be used for more than that! Upon opening I discovered that there was a 25ft 20amp cord included, which was great, one less cord I had to purchase! From my understanding, there is a pull start and an electric start version of this model. I have the pull start, which I was a bit worried about, honestly, see as how I always struggle with starting up the lawnmower, haha. But, I can honestly say, this was a lot easier to start up than I expected! This generator has huge heavy duty wheels and handle bars, making it soo much easier to transport it wherever I need it to be at in the yard! Also, the handle bars fold down and lock into place making it a bit more compact for those who are limited space! After checking things out a bit and reading the instruction manual, it's to my understanding that it is equipped with a nifty little feature, it has a low-oil level shut down feature that helps protect the engine from any damage! This is wonderful for those who are not used to checking their oil level or just completely forget because so much is going on! This generator is wonderful so far! I have not been able to use it for a super long period of time, but it has been used for powering a pressure washer for a decent length of time for a side job! I have confidence that this will work wonders for a power outage, work/side jobs or even for some camping trips! Very happy with it so far!

A good emergency power source. Provides peace of mind knowing we will be ready for the next power outage.

I just purchased a GP7500E generator. Installing the wheels and handle was easy and after adding the included liter of oil and a little gasoline, it started up immediately when I hit the start switch. I shut it off and tried the recoil starter as well and it started right up. I tested it with a power saw and had no issues. It is a little load, but much better than my previous 4000 watt generator. I am glad to know if we lose power in the next storm, we will be able to keep the lights on, have water and heat and keep the sump pump running. It gives me peace of mind.

Easy out of the box assembly.

Easy out of the box assembly. Took about 20 minutes to assemble. Everything you need in the box except the gas. Filled with oil, charged the battery and started right up. Noise level is less than I had expected....that's a good thing. Looking forward to using the unit for home backup.

Great brand ! Good reputation !

We have had a lot of power outages in the past year. I had a small generator, but wouldn't handle everything, I would have to shut off things then turn on things. With the New bigger model I can run everything ! Easy to put together, easy to run ! So glad I made this purchase !!!! My small generator is a General, had great experience with it, so that is why I recommend General !!!!

Quality Is Number 1

I purchased the Generac GP8000E after doing alot of research with several other brands. I am not disappointed, from the moment I started to unpack the generator I noticed the quality of the packaging, which gave me confidence in the product right off the bat. The engineering made assembly very easy! You notice the quality in every part as you put this baby together. The quality shows that Generac and its associates genuinely care about the product they put out to the consumer.

Great Value

Easy to set up. Large wheels makes it a almost effortless to move around. The extension that comes with the unit is handy when I move it off site. Normally we use this generator as a standby unit in case of storms and other power outages. We connect it to our transfer switch with a 50 ft. very heavy twist lock extension cord. Easy to start and relatively quiet. Great value for the money.
