Highly Recomend!!

I brought this generator prior to relocating to Puerto Rico this year. When Hurricane Irma then Maria hit the island in September, I ran it 24X7 to power my home. I could not be happier. Had refrigerator and lights everyday until the power was restored November 25th. That was 2 plus months. Never a hiccup and on we washed our clothes in the washer. I invested in a transfer panel during the outage and that made the use even easier/ The electric start is a charm and changing the oil is easy. 10 days after the power was restored the lights went out again. Went to my generator, pushed the start button and it went back on line. Went I turned it off after 2 months I kissed it because it helped my wife and I get thru a difficult time. Buy this unit. I am a very careful shopper and only invest in quality products. If I seem enthusiastic, it is because it performed beyond my expectations. THANKS GENERAC!!!

I'm pleased overall with the features and output.

I was surprised that the THD was high enough that my digital frequency meter would not read 60 Hertz either at no load or full load. I had to read the frequency with my ocilloscope. However the THD must be low enough so that it doesn't seem to bother my electronics. It starts easy with the pull starter. I'll probably use a bigger starting battery when the little one that came with the unit dies. The voltage is pretty stable during motor starts. Since the genset is heavy I would like to see a lifting eye to set it in a pickup bed. All things considered, it seems worth the affordable price for an 8 KW non commercial machine.

Poor Quality

I was really surprised at the poor quality of the generator I purchased in the aftermath of Hurricane Helene. The fuel tank leaked fuel. Once I got the tank replaced, the fuel petcock now leaks fuel. Even the replacement one I received leaks fuel. I would not purchase again, nor would I recommend purchase of a generac generator.

a couple of suggestions

Putting the machine together in a cold garage was a real "thrill". None of your vendors offered this service. The cotter key for the wheels is a real challenge. There has to be a better, easier way to do this little task. Many naughty words were said. For accessories, why not casters for the front of the machine?? Something designed by you, designed to fit properly, would be a nice feature. Try lifting this thing to pull it out of a garage when you are 70, with a bad back. Everything works as it should, and the directions are easy to follow, and it started the first time.

The big beast GP17500E

Haven't had a chance to run the house with it yet, but I'm sure it will make light work of it with no problem! The overall quality and appearance of this machine is very well put together. The only issue I had is that it took over 4 months to get it...I'm guessing it's probably production run intervals.

Great value for the price for emergency power

My wife and I purchased the GP7500E this year for use in emergency power situations after a great deal of research. We moved into a hurricane prone area af ew years ago, and were without power for several days after Irene with a one year old in the house. Since we're on well water, it was a miserable few days! Never again... The GP7500E was easy to setup for the first time, except for one small thing. Strangely, the manual called for 1L of oil, and provided a single bottle, but I found that it required close to 1.5 L in order to fill the engine crankcase appropriately. In any case, I was amazed how quickly the generator started at the push of a button. It runs like a top! Now my family is better prepared for the next ice storm or hurricane thanks to Generac.

Just what I needed

[This review was collected as part of a promotion.] I have used this generator a few times since getting it and I have been extremely happy with the product. No issues or concerns with starting and it provided more than enough power to supply my home during the outage.

Ample power and easy start

[This review was collected as part of a promotion.] This generator is perfect. Has a quick start button to make it easy for me to start. It operates off gas, propane or natural gas. It is quiet during running which is a great plus. Has a handle and wheels to make it simple to move around to where it is needed. Large enough to keep me in civilization during power outages.
