This is a great generator!

Come January 2021 this unit will be one year old.Every three months we charge it for 24 hours.When ever I go out and start it up THERE are no problems what so ever.I like to run it ever so often so I know all works find.We are lucky that we have not needed to use it for a back up yet!!You see we live in Northern Ontario Canada where we get lots of snow and very COLD weather! I know if and when the time comes this unit will stand up to it's job.

Only generator I considered buying.

Great product, well made, starts immediately with electric start. I only ran it for a short time after installing the house electrical transfer panel. Generator handled everything with no problem. I do wish that there would be an oil filter for the engine. I know someone with a 10,000 watt generator and that has an oil filter.

Electric Start and hour meter

I bought this unit for a backup power source. Do to my electric company not being the most reliable to repair outages. The unit was delivered and I set it up within a 1/2 hour. Fired right up. I like the fact it has an hour meter to let me know when maintenance is needed. Electric start is nice also has a pull starter if needed.

Excellent generator. First time owner, couldn’t have been easier!

[This review was collected as part of a promotion.] I haven’t used a modern generator before - last one we had was 25 years old, was noisy, shaky, and we’d wear ourselves out getting it to start. Oh, and then there was the exhaust, smoke and low current. Not anymore! This thing is a dream. Arrived well packaged and was a breeze to set up. Basically you attach the wheels, front rests and handle and it’s ready to go. Well you add oil (included, along with a handy funnel) From there, startup instructions are well documented in the book AND on the generator itself. I really appreciate that there are easy to follow graphical steps on the unit itself for starting and running the unit. A few quick pulls and it was purring like a kitten. I haven’t had a chance to put too much load on it, but so far it’s easily powered everything I’ve thrown at it! The unit is heavy, feels like everything is high quality, and I expect it to last a long time. Definitely recommend!

Great value

I did a lot of on line research before my purchase. I found this unit on sale for an incredibly low price that pretty much made the purchase a no brainier compared to the other Generators on the market. I haven't had the need to use it yet but do start it up once a month as per instructions. It's very easy to start. The only reason I didn't give it 5 stars is because it is a little noisy.

Best " bang for the buck"

After researching and using other products, such as Honda. I could not help but know that my GP6500 is the best bang for the buck! I know the dependability of generac having owned one in the past ( used it as an enticement on sale of my previous home). This particular model will also give a surge of power when increase of load is needed . With proper maintenance there is no reason it should not last a very long time. Very comforting to know the dependability of the generac name. Living in Florida having dependable back up power is essential. Sleeping better knowing I now have it!

Awesome generator!!!

I bought 2 of these after Hurricane Helene. One for me and one for my mom. My moms house used theirs and was plenty of power to run almost everything except the HVAC. Assembly was straight forward and started right up. Only used it for about 10hrs before her power came back. She was out for a total of 6 days. I never started mine because my power came back while I was picking them up lol.

Very dissapointed

Brought my new GP8000E generator home, unboxed it, assembled it, prepped it for the first run and then started it and watched as gas ran out of the air cleaner box. The only way I could get it to stop was to siphon the gas out of the tank. Apparently during the manufacturing of the unit someone mis-installed, mis-assembled or mis-welded the internal tank vent tube allowing gas to leak continuously from the tank. Serious safety hazard if I had not caught it. I went and talked to my local Generac reseller service center and was told they are 1 to 1.5 months backlogged but go ahead and drop it off, and of course he had never run across this issue before. Will I be buying another Generac product again…… NEVER. And for you wondering why I don’t give them a second chance…. this was their second chance. I had bought a smaller generator about 10 years ago for emergency use only. It only got started every 3 months and ran for an hour. I changed the oil and as it was draining out I saw aluminum particles coming out with the oil. So it only had a few hours on it but the engine had deteriorated internally and was past the warranty so it was junk.

Great Generator

This is a great unit. I live in a colder climate in a home with base board electric heat. The unit handles the house load well. I had no problem with the 2 ton heat pump/air conditioner. Assembly was easy enough, but instructions on wheel assembly could be improved with larger diagram. This unit is heavy. The pneumatic tires are good. the only negative is the wheels should be bearings instead of bushings. This could make the unit a little easier to move around. Unit is a little loud, but that can be expected with a 30HP engine. A second muffler attachment could help if it didn't place to much back pressure on the engine.

Great product

Purchased the gp6500e in case of power outages from hurricane Irma. Works exactly how you would expect. Instructions could be better but common sense goes a long way. The single quart of oil brings the unit just past the low mark on level ground, good thing I had backup oil on hand. Battery came with enough charge to start it right out of the box. Has been running constantly with no hiccups. 9/10 Would buy again!
