Very simple to start and use.

No brainer start and stop generator. I researched generators to buy and always settled on the Generac. Then I stopped by my neighbor/electricians house to see his setup and he had the exact model Generac I had planned on purchasing. He endorsed his model and installed mine and I couldn't be happier.

Mighty Powerful Standby

First of all Generac is the best. I have purchased many industrial generators for hospital backup. I know that Generac is quality. This unit meets all my needs for home backup without having to go to s standby unit. It was easy to assemble and started right off the bat. Much quieter than expected for its size. This unit is well built and I am sure will last me a lifetime. Fuel tank capacity and placement are optimal and I really like the built in strainer. I am very please with this purchase.

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.

Safety!

[This review was collected as part of a promotion.] Put oil and gas in this baby a she fired right up, didn't skip a beat!! I am so happy and relieved to have this "security blanket" just in case of a snowstorm, as our main heat source comes from a pellet stove. I feel safe now that I have this reliable backup!!

GREAT GENERATOR--EXCEEDED MY EXPECTATIONS!

Assembly took less than 30-minutes and it started effortlessly right out of the box. A “field test” of the new generator was conducted two days later. After a two hour test run, with all the transfer panel breakers turned on, and nearly every component of a “normal load” placed on the generator--from the well pump to the dishwasher, and from the furnace to the refrigerator & water heater--the GP7500E generator handled the load effortlessly. However, I've recently discovered one issue that remains distressing. In the owner's manual, Generac DOES NOT recommend running the generator in rain or snow. This is equivalent to a "Catch 22" in back-up, emergency power! After all, inclement weather--blizzards, hurricanes, tornados, ice storms, etc--are the causes of power outages in the first place creating the need for back-up generators! So the food in your refrigerator must spoil because it's raining outside? Really?

It took me less than 30 minutes to put on the wheels and handle, put gas in the tank, and start the generator.

Set up was fast and the directions made it easy. We ran the generator for 60 hours straight only stopping to put in gas and check the oil. The generator started quickly and never gave us any issues. We used the 220V outlet to run power to our breaker boxes. This allowed us greater comfort than running many extension cords.

I recommend this product

The generator is easy to use and to move around. The portability makes it useful in a number of different situations. The generator is a bit noisier than I would like, however, the convenience and ease of use out weighs this distraction. Should we experience another hurricane, we will be quite comfortable and safe. We plan to have this wired into our system so that our whole house will have power in the event of an extended outage.

No Doubts, money well invested

I am very satisfied with my purchase of my GP6500E generator. It was money well invested. The quality and performance of this Generac generator is great. The installation and startup directions were very easy to follow for someone like me that is not to keen on the mechanics of putting something together. The motor is not too noisy at all, we can barely hear that our generator is on at all when working. I will definitely recommend this product to all my family. I am getting ready to purchase a Generac Home Standby Generator in the next few months.

Generac GP 6500 series generator

This is a very good product, easy to put into use, and I can effectively use it to run everything I need in an emergency. starts easy even though it doesn't have an electric starter. I would by it again. We live in an area where storms take out power frequently. The transfer switch was easy to install as well.
