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.

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.

Battery charger

I have had this unit for three years now and fortunately have not needed it......yet. I do maintain it regularly and it seems to run well One question......is there a specific position that the start switch should be in when the generator is stored and the battery is charging (supposedly)..? The push start will not work any time that I try to start it....I always have to resort to the pull start. This will be hard for my wife if I am at work when we lose power.....one of the reasons I chose this unit. I store it with the battery charger plugged in as recommended but the battery never has enough to start the unit. Any help would be appreciated.

Nice to have.

[This review was collected as part of a promotion.] I was so excited to finally have a generator. Where we live the power constantly goes out even if it’s a small storm. It stays out for hours and hours and we have three children and most of the time we weren’t prepared and had no batteries ready so we sat in the dark. No fun at all. Now I feel so much better because when it goes out we will still be able to have a couple lights on and a space heater. It gives me so much peace of mind. My husband had to take it to work yesterday and he said it worked great! Started up on the first pull. I definitely recommend this generator.

i love my 17500

in the north east in new hampshire we lose power a lot.i bought the generac 17500 and have used it about 7 times in the past 10 years. it ran flawlessly and the girls were very happy at home which made my life very peaceful for the week to 10 days we had it running.the only time it never started is when i neglected to keep on eye on it's battery,if it just sits around for a year or two the battery will lose it's starting power when you need it.ever so often put a charger on it so it's alive when you need it.

Bad Bad Bad

F...ing garbage. Do not buy. Runs rough if it starts. Worst generator I've ever had. I would say used but can't hardly use it. Bought new. Was garbage right out of the box. Should have returned. Spen up and get a Honda. This thing is junk

Great Generator

Purchased the gp6500 after a lot of research. It offered the best power for the price. We only had to use it for a little over 1 hour for the first 7 months we owned it. We have been faithful in starting it about every other week or so and ran it with a load for about 20 minutes. We have kept the tank full of gas treated with stabilizer. Well sure enough we lost power this week do to freak March snowstorm. Started on the second pull. It ran over the course of three days for 29 hours. Worked flawlessly. Really a lifesaver, especially with three kids and the wife. Ran 3/4 of the entire house including a well pump, two refrigerators and a deep freezer. We have a Woodstove in the basement so no need for it to run a heat source. Bottom line... Awesome product, great value and so far seems durable. If you're debating this generator, go for it!!!!

Should do what it is designed to do

It was a gift from a son-in-law. I have started it but have not used it as we are still trying to get our house wired for it. One complaint was that the manual with it was not very good so I had to down load one from the web site. Also it arrived without the axle but when I called Generac they shipped one right away.Since it is so heavy I had to get help in installing the wheels and axle. The Generac people(Power Solutions ) in Jasper, GA did send a man over and he did the work for me and made all the proper assembly needed and was very friendly. This generator is to be used in case of power outages that we have often..

Unbelievable performance and reliability!

I've owned this generator since April 2013 and have used it to its limits with zero issues and 100% satisfaction on my part. We started construction on a new home 2 months (June 2013) after our purchase and due to our utility company's inability to bring power to our rural location until August, we were forced to use the GP17500E to supply power to all of our contractors. We put 200 plus hours on this baby throughout the concrete, framing, electrical and plumbing rough in, and getting about half the shingles installed. Big cost on Gasoline, but kept us on schedule and everyone working. It now serves as a whole home emergency backup power supply for virtually every circuit in my home through the 6380 Manual Transfer Switch. 2000 square foot home with a geothermal heat pump and 4 ton A/C, all lights, power outlets, appliances, hot water, entertainment system, computer. It's easy to operate and switch between Utility power and Generac. We are conservative on power usage during outages, but incredibly comfortable during our Kansas winters and summers!!! I will never be without one of these generators on hand and wouldn't even consider another brand.

The Product has what I need

I have only owned this product for a short time but it powers my furnace, sump, fridge & freezer. I have not pushed it any further but that's the coverage I need if I get in trouble. However; I would like to have some one tell me how to replace the muffler. I want a very portable & quiet power source!!!
