Purchased for house backup. Needed portablity with power for my situation. Unit performs as advertised when tested at 12kw , no-load to full load and v-v <3% voltage or freq variation w/ <5%thd. Runs my 4ton ground source heat pump ( has soft start) and 2 refrigrators plus rest of house minus range and dryer easly using the 50 A. connector. Power is clean and well regulated for sensitive electronics in house. Portablity is good since i lift it with tractor loader to move from house use to other areas. Thanks.

Just bought this generator yesterday for use as a backup power supply. This product is well built and will fit my needs perfectly. Assembled quickly using the included "Quick Start" guide, added oil and gas- hit the button and it started right up! Not looking forward to a power outage but happy to have this generator to keep everything running in my house if there is an outage.

Pre read the manual online the day prior to delivery which made the startup effortless. Assembly was a breeze and it srarted right up with ease. Ran it for about 30 minutes, loaded an air compressor, portable heater, and shop vac just to test. Then tested the whole house, 2 fridges, freezer, furnace, gas water heater, and numerous lights. Flawless performance. Expect to survive the eventual power outage this winter and next spring.

Had to replace my old generator (That was not a generac) that had for the last 15 years. Bought this from a local vendor. The unit started right up. I already have a generac home standby but It really uses the propane to run all night. I use this to just run fridge and furnace at night. The home standby was the best purchase ever. Soon as the power goes out the standby will start right up. I have the 6500 run just a few circuits when don't want the standby running. The 6500 has electric start which is nice. I was without power when 1st bought and it ran for 16 hours straight. No problems. I would recommend the generac name to anyone. After bought my home standby my inlaws bought one and love it. Highly recommend the portable 6500E.

We recently lost power for 10 hours and this generator was just what I needed. We have a sump pump in the basement to keep it from flooding and this generator did the job with keeping the electric going. What a lifesaver. I am so happy that we purchased it. I wanted a Generac brand because they are made in America and have a great reputation. Semper Fi.

I have had this 2 years, I have run it 60 hours. The gas tank leaks where it bolts to the frame. It's a bad design or poor manufacturing, Not made in USA for sure. Too many models and design changes to keep track of in my opinion. Just trying to get the tank replaced has taken 6 calls, 3 emails, and still no results.

I purchased this unit (GP17500E) for home backup power for my CT home. I have been trying to get a dealer / service rep to assemble the unit at my house - for a fee- and spare me the effort of having to lift a 400 pound unit to assemble the wheel kit (I have a bad back)....So far all the service reps in CT have turned me down. One told me they are not taking any more portables...Just be aware that if you purchase this product you'll be on your own trying to assemble it...

Here in the Northeast we just got pounded with a winter blizzard, power out for 5 days on my street. Our Generac 6500 performed up to my expectations and then some. 90+ hours of straight run time and didnt skip a beat. We had this unit wired direct from our service panel to tranfer breaker panel with an outside outlet and 20' cord. 2- Frig's, heat, kitchen lights and outlets, microwave, livingroom lights and outlets, 3 bedrooms lights, office lights and outlets, garage lights, 2 bathrooms lights, cable, internet, tv..

got this unit from local home depot for irene .only one i could find find from here to canada bolted on wheels added oil and gas fired up and ran with on problem for 6 days till power came back on. great back power for your home , i will tell all my friends to check it out ..

Bottom of box and pallet was taped to pallet. I signed off, delivery driver drove off. 3 hours later, at 6:30 pm I took off the tape to see that somewhere in the process the tape was used to cover up a number of big holes and the powder coated frame was scraped up in 5 places. The battery tray flange was bent. Forklift damage I assume. I'm asking retailer to contact Generac and get me touch up paint to avoid rust... and a return.... I'm in the process of breaking it in. Lets see how Generac handles this, and I'll report back. Somebody tried to cover up a mistake, and it does not reflect well on the brand.
