Sandy and Generac - a good combination

Just made it through hurricane Sandy's blackout. This was the generators first extended test. Passed with flying colors. This is the 6500 Watt model, manual start. Started on the second pull (usually does). I Powered, using the 30amp outlet - 1 Refrig, 2 gas forced hot air heating units, 1 gas powered water heater, 2 bathrooms, kitchen lights, dinette lights family room outlets (charged a lot of cell phones), and used applicances through those outlets (toaster over, coffee maker, washer/dryer), and of course a radio, hall lights and a bedroom. Using the 20amp four outlets, powered three more refrig, including a couple from my neighbors house, and some additional lights. The generator took forever to use the gasoline in the tank. No lights flickered, appliances functioned proprely. At times I forgot I was on generator. Thank You Generac.

This product quit working

It only ran for 4 hours and stopped producing ac power to our house. When we needed it, it failed. I called and was given a number of a dealer that could fix it. It is now in the shop. I am waiting for it to return, fixed I hope. After my experience with this generator I would NOT recommend anyone buy one.

It will definitely work for you.

I had this delivered to the house. The packaging was very good. No damage. I did all the assembly within a half hour. Filled it with oil and put some gas into the tank. I used the electric start and it started up with no problems. Temp outside was less than 5 F. I bought the electric start only for my wife so she could start it up if I wasn't home. The manual provides all information needed to star and maintain the unit.

Recommend

[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!

POOR WARRANTY AND PRODUCT

I bought this generator just under a year ago. We were expecting power outages up to several weeks. Glad that we weren't effected. The reason for my 2 stars is the Generator is supposed to have a great warranty. Buyer beware, after putting the generator together and trying to start it the generator failed to start. I called to have someone to come out to check the generator and was told that I had to bring it to a place. So a generator that weights over 100lbs with a full 7 gal tank of fuel they expected me to transport over 25 miles to have it serviced. I would NEVER buy another product from this company.

Great value

Bought this generator for home backup in preparation of hurricane season. Compared to other generators at the store it offered the most features for the price. Put the oil and fuel, hit the electric start button and it started right up. Ran it for about 15-20 minutes and found no issues. Looking forward to having electricity next time a hurricane comes though.

This generator is a beast

[This review was collected as part of a promotion.] The Generac GP9500E Tri-Fuel is a fortress of reliable portable power. It stands out for its substantial output, multi-fuel adaptability, and safety focus. While it leans into simplicity over tech-savvy features and isn't the lightest or most efficient, it packs an outstanding value for serious backup power needs.

Very nice and works so well

[This review was collected as part of a promotion.] The photo shows it on its side because the wheels were being put on. However the wheels make it much easier to move around and the handle is even a better touch. The noise is not as loud as some I have heard and it was easy to start with the pull start. We plan to connect it to the house so it will run a few major appliances like the deep freezer and fridge.

Worked perfectly

I was contacted by a neighbor that our area had lost power, and bought a GP6500 on my way home. I followed the operator manual, it started right away and I was able to save the food in our freezer and fridge. In my mind it has paid for itself. This is just the right size to cover critical needs during summer and winter storms.

Great Generator To Have After The Storm

We recently purchased the Generac GP6500 and couldn't be more pleased with this product. This generator had its fair share of use after the recent damage caused by hurricane Florence in the coastal region of Eastern North Carolina. The GP6500 generator was easy to assemble and started up on the first pull out of the box. The generator ran continually throughout the daytime hours for a solid week after the hurricane had passed through our area knocking out power to our subdivision. We had NO issues or complications with our Generac GP6500 while we were waiting to have our power restored. Also, we noticed that the full burn of the generator seemed to be more efficient than expected. This was a major relief to us since all gas stations in our area were closed due to lack of available refueling trucks as well as there was no electricity to operate the gas pumps at the stations. Not having to worry about running out of gas for our generator was very reassuring. Not only did we use our Generac GP6500 after we lost power at our home we also continued to use it as we participated in various clean-up projects for others homes who suffered severe storm damage in which utility power was not able to be restored. The GP6500 was small enough to be transported to various worksites as home repairs were needed throughout our region. Again, we used our generator all throughout the day while we operated electrical equipment to assist with clean up and various home salvaging activities. We've since winterized our Generac GP6500 (which was simple and easy to perform) and have it stored and ready for the next time it is needed. Unfortunately, living close to the coast in North Carolina results in yearly threats of hurricanes. However, we are comforted knowing that we are prepared for any future storms and power outages with our Generac GP6500 ready to go in the garage. Good Job Generac!
