Great Portable Generator

We lost power due to a storm and it was going to be at least of couple of days before it came back. I bought this one in a pinch but hindsight I'm really glad I did. Very easy to operate and starting was a snap. I was easily able to run my two refrigerators and three freezers, with room for more. I'll get this tied into the house and be able to run my well and furnace as well. Great product!

Excellent

[This review was collected as part of a promotion.] We finally were able to try it. He is a beast! It can power an entire home. Everything was in the box to assemble it. Very heavy ( I think it’s more than 230 lbs). It has tires that need to be installed so it can be moved. The noise is not as loud as I was expecting. Has a lot of power. Runs on gasoline, propane and natural gas.

Love it

I had an old 12,000 or 10,000 watt Generac not sure what year it was that would run my house off transfer switch. It came with the house n was stored under wood box by transfer switch. I bought the house in 1993 and bought a new cheap generator in 2012 to replace the old Generac . I never used the new generator that was a 12,000 watt other than letting it run a bit every 3 months. We had a bad storm in 2020 and I used it everyday for a week till it came apart n the air filter caught on fire plus I could not run a lot of stuff in the house. I just bought the Generac 1500 and used it once on a power outage n it ran whole house. I’m impressed with the quality of the Generac

Hurricane Auxiliary Power

I bought a GP8000e 3 years ago but didn’t need to use it until now. I turned this generator on Wednesday night after hurricane Ian had passed. It’s been running for 5 days straight. I do change the oil every day, not sure if that’s necessary. It’s been running the lights, two air conditioners, tv, refrigerator… I’ve even used the washing machine.

power plant of a generator.

This is a great generator for our entire house. No shortage of power and seems to be built solid. I really like the fact that it came with a battery charger to ensure its always ready to go. It's a little loud but not outrageous. Great generator dollar for dollar. We are ready for another ice storm with this Generac.

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.

Great!!

[This review was collected as part of a promotion.] Compact, reliable power. This GP9500E from Generac has a small footprint, yet packs some serious power. This is capable of running on gasoline, LP (propane) or natural gas. Rated at 12500 starting watts and 9500 running watts when running on gasoline. The 500cc OHV (over head valve) engine features electric start with the included battery, as well as the old school pull start just in case the battery or something fails. It holds 7.5 gallons of gasoline and will run 9.5 hours at 50%. There is an included 4 foot long LP adapter hose and a 20lb tank will run 4.5 hours under the same conditions. Propane will lower the output slightly at 11250 starting and 8550 running watts. If you run natural gas it lowers it to 9000 and 7000. The included handle and wheel kit makes it super easy to move it around when needed and the handle folds down to store neatly. There are many great features built in, such as covered outlets for added protection when being used in the elements, CO sense technology that will shut the machine down if CO levels get too high and a low oil l cel shutdown that will stop the engine if it detects low oil to save the engine from damage. It is also compatible with HomeLink manual transfer switch kit to help power your home in the event of a power outage. This is especially helpful at our house as we have a well and when the power goes out, there is no water. So this adds peace of mind in those situations. Setup was simple with the included directions, which are also printed on the top flap of the box. Everything you need aside from a couple of very basic tools is included as well. The front panel contains an hour meter to keep track of how much use the machine has had. When running this is on the quiet side for a machine of this size. I am extremely pleased with this generator. From the ease of setup to the ease of use this generator is awesome.

Power When We Need It Most!

Guess I’m turning into my Dad….have been wanting a Generator and finally broke down and bought one. Chose this model due to its capability to power most everything in my house and due to it’s ease of use if I’m at work and my family needs to use it. I also installed a Generator service to my house to make it safer to hook up in the event I’m not home. Haven’t got to use it yet other than a few test runs. Honestly hope we don’t need it but It’s a Generac so it will be ready when we do.

This Generator is excellent .

I have not had a chance to run this generator for an extended period of time yet, but I know that it is easy to start and has sufficient power rating to run a refrigerator, freezer, television, a microwave, and two electric heaters, and a few lights during a power outage. Easy to roll it into service and place into service.

Seems well built

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
