Purchased it for piece of mind. I have only ran for about 6 hours so far and that was for the break in and multiple oil changes. One of those hours I did have it hooked up to my house and it powered everything I wanted with extra watts to spare ( that's why I bought a bigger one I read you only want to use about 60 % all the time to last longer) seems well made . only complaint it does use more gas per hour than other comparable models but that's it

This is a great product for the price.The generator starts easily and runs fairly quiet.The fuel tank is huge and i can get about 8 hours out of a tank.I gave it 4 stars for only one reason and that is because of the wheels.This generator is very heavy and they should have sealed bearings on the wheels because when you have to move it on grass it is hard to push or pull.

Love the product ,i purchased this generator right after a recent storm .it ran really well and then started giving an error on the co2 sensor. I now need to take it to an authorized repair shop. Strange because the generator was out in the open .it was only 1 day after purchase

Bought GP8000E in Feb 2025. Only had to use 4 times, had no problems until now June 20, 2025. Now one of the GFCI output units keeps tripping after 7 seconds with nothing plugged into it. The reset button keeps popping out. Tried pushing the reset button also. The GFCI is bad, this problem should not be happening after only 4 uses. The unit is only 5 months old. Generac reports they have none of these GFCI units in stock and do not know when they will be available to ship. Generac service dealer tells me I need to leave the unit with them and possibly in 2 to 6 weeks they may get an new GFCI unit. UNBELIEVABLE !!!

After losing power for 9 days during Sandy, and just missing the bullet during the winter of 2014, we decided to quickly purchase this generator to avoid future problems. Based on earlier research I looked for a Generac and found one by luck at a local dealer. The generator is VERY easy to start and use, and powers almost our entire home - no need or a full house unit! Excellent price - including transfer box installed about $2000 total - well worth it for peace of mind!

If looks meant anything, this is a killer of a generator. I took back a B & Stratton, then bought this. Works great, easy to set up and works flawlessly with the your Manual Transfer switch. Generac is second to none when it comes to generators. Jeff M.

Having no backup plan for heat and concerns we may lose electricity with forecasted temperatures at -33°. I wanted piece of mind knowing it would sufficiently power our furnace and any other things we need. Started right up on first pull, battery wasn't charged straight out of box when I did initial start, but works now that it has been charged. Great product.

[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!!

Only time will tell if it holds up well over the long haul, or if the investment was a poor decision. Realistically I don't believe it is meant for heavy duty service, but if taken good care of, and with only emergency duty, I will expect a long service life (many years) of reliable service.

A lot of features for the money! This unit delivers emergency power for our whole house, except for the oven and dryer. With it, freeers and refrigerators have enough amps to start their compressors, something smaller generators do not! Also, It has overheating shutdown, which is a great reliability feature. The only problem we’ve had so far is with the battery start. the terminals on the battery come loose way to easily. An inexpensive alternative to the permanent generators, which can easily run over $10000 installed.It is sad that we have a need for this technology, when our parents had cheap reliable energy. And it all could of been avoided.
