Great unit

I live in an area that is rural and the power goes out a few times a year. A month ago we had a storm and lost power for about 24 hours. I had a little generator but it was only good for a couple lights and t.v.. Problem is I have a refrigerator, a freezer, and a well pump I need power to as well. Next week I went looking for a bigger more reliable generator and found it with my generac 6500. After I got it home I was actually hoping to have another storm knock the power out so I could see how it would do. Wasnt long and it happened! It was only about a week later another storm came through and knocked the power out for about 7 hours. Long enough to try out the new generac. Rolled it out easy enough even though it's pretty heavy, pulled once and it was running like a champ. Plugged in the necessities and it handled everything. It was so nice to have in that situation. This winter I plan on having a transfer switch so I can run everything from lights to heat. I'd recommend this generator if your looking for one.

Indestructible!!!

I’ve only got about 10 or 12 hours on my 6500 but I am amazed at how it performs after surviving two floods in my garage!!! Both times the water got high enough to fill the muffler and reached the electrical outlets. Both times I drained the water out, checked the carburetor and changed the oil to be safe. It fired up, steamed out the remaining bit of water in the muffler and ran as though nothing had happened. I was sure I was going to have to spend a lot of money to get it up and running again. I’m very impressed with my purchase. I’m staying with these guys.

Great overall unit but…

We purchased our generator just before hurricane Helene came through as our older generator of 20 years stopped working. The new unit worked fine for the week we were without power but started dripping some oil the last two days. After speaking to Generac and then taking it to an authorized repair dealer we were without the unit for almost six months due to no part available. Thankfully we didn’t need the unit as we never lost power during that time but that is way too long to wait for a repair.

Unreliable, dies in the rain, poor support.

Received brand new just a few days ago, ahead of a big storm. It ran for five minutes and then died as soon as it got a little wet. Tried restarting, but it shuts down immediately every time. Throwing fault P1600, which nobody knows what it means. Generac L2 support is largely unhelpful and can only advise me to disconnect the battery (which did not fix anything). Let it dry out for an hour and it ran for another five minutes before dying. None of the local service centers have the time or experience to work on an EFI generator and will not service it. In New England, a failed generator can be life threatening. This will be my last Generac. Not reliable at all.

Tri fuel generator

[This review was collected as part of a promotion.] This generator is perfect, nice heavy duty with the ability to run gasoline, liquid propane or natural gas fuel source. It is easy to switch between settings. It is heavy but with the wheels is portable and easy to move. It definitely makes noise, but to be expected with the size of generator and it’s tolerable. Perfect for emergency/power outages, job sites/ tools and camping. Well worth the investment if looking for generator, especially with the tri fuel option!!

This is a great product

This product gives us more for our money. After being without power for 38 hours and losing everything in the refrigerator and freezer for the second time this year we decided to buy a generator and generac was rated as one if the best. Bought one and had an electrician come and install it so from now on we have piece of mind when the power goes out again. Price and the ability to power so many things at once was a no brainer. Thanks for the great product.

Finally was able to use my GP17500e

I purchased this generator new approximately 5 years ago. I left an initial impression review at that time. Other than monthly test runs, I have not had to use it. Last night it was finally used to provide power for the entire house. It worked flawlessly. It was 28 degF. When I started the generator and it ran continuously for 16 hours with no shutdown. Temps got to a low of 6 degF. It’s one thing to lose power in the summer. Losing power when it is in the single digits is an altogether different scenario. Our house has baseboard electric heat that had to work in some rooms not heated by the woodstove. In conclusion, and as a follow up,after five years it did exactly what is what purchased for.

This product is...."The Beast"!

Have owned a 7,000 exl by Generac for years and never a single problem. Made the decision to purchase this GP17,500 watt beast. Very impressed with the quality of this unit. Fired up without the choke on first start out of the box! Have only ran for an hour doing a break in, so haven't put a load on it yet, but I can tell the Beast is ready! Thanks for a well made product!

This product had all i needed for what i needed it for .

Dealer was great (electric generator direct). i would have given this item 5 stars but pull cord did not work correctly after 5 to 6 pulls . i had to get it fixed (for free) but little bit of a pain ,but runs all that i need to run ,best part is its on wheels so i can take it any where .

Good machine. CO sensor and GFCI to sensitive

GFCI trips when I plug in my refrigerator. CO sensor keeps shutting down my unit that is placed outside not even close to my home. I had to put a box fan under the handle to blow air across the unit to keep it running. I dont need the CO shutdown. Other than those 2 items I am impressed.
