Great value

I am a female, own a home and needed a generator I could handle in an emergency. I am able to move this generator, fill it and start it with no problems. It is reasonably quiet. It runs for a significant length of time without needing a refill (+/- 6 hours). During a weeklong power outage during a tropical storm, it kept my refrigerator on, my sump pump going, some lights on and I was able to charge my cell phone. It did everything I needed.

So Far So Good

I just purchased the GP7500E for emergency backup for our house. We experience several power outages during the winter. This is my first purchase of a portable generator. It was easy to assemble. I added oil and gas, turned on the fuel, set the choke, pushed the start button and it started right away. It even comes with a battery charger. This will be the perfect back up power for us. It is a little louder than I had hoped but, we can get over that when the first outage happens and we have power in the house. It is connected to a manual transfer panel and the change from hydro to back up is very easy to accomplish. Come on winter storms!!

This is a tentative review

Out of the box looks great, easy setup and starts easily 1x per month for testing ( starting) only). Today I needed it most with an ice storm and power outage. Fired up and ran great, but produced no electricity from the outlets. I took it into the service center, but still had a dark cold house. I will update with my service and warranty experience.

Solid performer after fixing battery issue.

Solid performer after fixing battery issue. The battery died after 6 months and would not hold a charge. After installing a new battery and a disconnect so the battery no longer had a drain on it, I also installed a motorcycle style trickle charger. It now works perfectly and the battery holds a charge. I keep the battery disconnected until it's time to use it. It is now a perfect generator after the $50 upgrade. Too bad Generac did make the improvements in the factory because it does take a certain amount of expertise and engineering to correct the problem but is doable if you have the right tools. I will attach some photos at a later date.

Seems quite good at this point.

Have only run a few tests in the first 3 days of owning. Time will tell as to reliability and durability. Price reasonable. Noise level is pretty high but placement is critical. and in our case not a significant issue. Looked at others, but this seemed to exhibit best combination of size,price,reputation,and warranty. So far so good.

Good generator

I moved in to a new Home, outside of the “city”, and knew that consistent power would be an issue. I chose generac brand due to their reputation. My power has dropped out twice in 2 weeks. After wiring my portable generator to my home, it has performed flawlessly. I am more than pleased so far! I refuse to let my baby girl be without heat, and this generator supplied it, plus my coffee maker, lights and outlets.

Just the right size for household needs

[This review was collected as part of a promotion.] I got this 3600 watt generator about a week ago and I am so glad I got it. I had been looking into getting one since Irma came through and we lost power for a week. Now I have one big enough to run my chest freezer, refrigerator, a lamp and a fan. The box came damaged, but the product was in tact and had all the bolts required to put the handle and wheels on.

this product has great features

i highly recommend everybody having a generac generator as an emergency backup after going through hurricane irma and having no power for 8 days and we lost all of our perishable food in deep freeze and refrigerator because we did not get generator until after the storm but so glad i ordered it because of the unbearable heat in florida and we were able to run window ac's and well to take showers very satisfied.

All good! Love the dual fuel. I do wonder if I can plumb the fuel from our home propane tank? or possibly use my 100# tank vs only a 20 or 30# ? It's perfect as a home backup, as is, just thinking of a fixed backup rather than having to run sep tanks & wire.

Ran for 4 days straight

This seems to be a good generator is provided backup power for me for 4 days straight. The only thing I wish the generator had was a percentage used of power as other generators offer that feature. The only feature offered on this is the hour meter which is very good for maintenance
