It saved the day

I purchased my RS 8000E for back up power in April of 2020 and had an electrician hook up a box to my breaker box so i have power to the entire house. In October we lost power for about 5.5 hours due to heavy snow and transformers were blowing out all over the area. We had just sat down for dinner with our three daughters and there boyfriends, needless to say we were the only home with power that I know of in more than a 2 mile radius. The generator worked great. I feel if you need it, it will pays for itself after just a few uses. I would highly recommend this generator.

Reliability, Value, Price

Thorough research and customer satisfaction, were the basis for my selection. Review of the product was simplified by the product manual, which was most informative and easy to understand. I will be getting a quote for the home standby system as soon as possible. In Florida, a generator is as necessary as homeowners insurance.

Don't they test these things before shipping them?

The generator arrived pretty quick after ordered. I followed the instructions of getting it set up (adding oil, gas, hooking up battery, etc). The generator would not start with the electric start button. I verified the battery was fully charged. It would start manually with the pull cord. I contacted Generac and the closest service facility was 45 minutes away. I dropped it off the day before New Years. I did not receive it back until January 30th. Part of the issue was they could not get the control panel off without damaging the decal that labelled the switches and outlets as it covered the screws. They had to replace the solenoid and repair a wire. They made that repair relatively quick and offered to give it back with the damaged decal. I told them that after spending $1100 for it I would prefer to not have to look at a damaged decal every time I have to use it. The service facility was nice enough to deal with, but they kept the generator outside for awhile. When I got it back it was filthy. In closing, my experience could have been better. But the unit works fine. This could all have been avoided if it was tested before shipping. I also want to note that I bought this because it was made in the US.

[This review was collected as part of a promotion.] This generator is awesome. You can use gas, propane, or natural gas. Super easy to start and works great during power outages. It runs for a long time and has safety features too. Really happy with it!

Good Product

[This review was collected as part of a promotion.] The unit was package very well and sturdy in the box. This is my fisrt time assembly a generator and this one was pretty easy. It only took about 45 minutes. I test this unit for about 4 hours for a total of five days. It is not as loyd as I thought it would be. No problem hooking up my cords. It has a twist adapter which is a plus. It also show how long you have for power. Lastly, I finally took this to a tailgating event. This works so well. Everything worked so well.

Reliable, well built, delivers when needed, keeps us safe

The GP8000E Generac Portable Generator is the first generator we have acquired. Its no nonsense starting instructions make it easy to start the generator. We read through the instructions completely and started it same day we purchased to validate reliability and our know-how and it started immediately and safely. Instructions are easy to understand and follow. We look forward to having it up and ready to go whenever we may need it. Safety directions are clear and thorough.

Seems great - just bought - missing a piece

I just received the shipment and set it up for test run. The setup was easy (using my tractor to get it lifted off the pallet so I could install the wheels). Started right up and made electricity, so all good. Then ran it back out of fuel and disconnected the battery so it would store well. Overall, all systems go. Needed this size to run my 5HP well and some other selected items during power outages for hurricanes. Couple of points: 1. Generator arrived missing the fuel supply line from tank to carb. I didn't want to call and wait for Generac to ship me one, since I know it was only a $5 purchase at the local auto parts store. 2. It would be nice for the instructions to give a recommended amount of oil to add at initial set up. I had to add a little, then check the stick, and repeat until I figured out it took ALMOST 2 quarts. For fear of overfilling, that took longer than it should.

High quality

[This review was collected as part of a promotion.] I am extremely pleased with this Generac generator. My husband and I had no problems whatsoever setting this up. It’s actually not as loud as I suspected it would be, maybe about the same noise as a lawnmower. We were able to hook quite a bit with this (refrigerator, few lights, microwave,etc.) This will definitely come in handy this winter as we’re in Western New York and get some pretty harsh weather and are constantly having the power out for long periods of time. Definitely a good investment and this generator is high quality and highly recommended!

For 50 hours then nothing

Bought this unit to get us through the storm last year. It did it's job well for the first 50 hours, then it quite running. It won't start and run. Pretty sure it's the electronics, the CO2 sensor. Saw a U tube video of the exact model doing the exact thing. Bad unnecessary CO2 sensor. So it sits there broken waiting for me to find a shop, time, and help to load it.

Great power without breaking the bank

I had researched several brands and models of generators and this 7500W model topped the list each time. Bought it to run tools for home renovation jobs and backup if power was ever lost at home. Does everything I need it to do! Great power for the price! Only downside is noise. This is supposedly noisier than most in its class. This is not an issue for me, but if it was regularly used go home backup, I'd consider a quieter one for running throughout the night.
