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.

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.

Powerful

[This review was collected as part of a promotion.] What a powerful generator, it packs a lot of punch!! Great features like the electrical outlets, the size is compact and convenient and is actually a bit more quiet then I expected (it's not quiet, but definitely not the loudest I have heard) I think everyone would should have something like this for emergency purposes and recreational use. I would absolutely recommend this to all my friends and family.

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.

Proud Owner!

I have always wanted one of these generators, the reputation is backed up by it's performance. Unit is packaged correctly to prevent damage. Unit is extremely easy to assemble and set up. Started up almost instantaneous the first time, and all the features are very easy to learn. I plan on using with a power transfer switch to power my house when power is lost. Great product, great company, great reputation!

great generator

Great generator for the price! easy set up. It also will be easy to maintain.Easy to start. just to see what i could run with it i put it through its paces. I ran 5 lights, 2 fans, 3 electric heaters, well pump, refrigerator, freezer, heat lamp, garage door opener. it ran all of it without any problem. I was bold enough to run all the above and turn on the hot water tank. now thats when the generator knew it had a load on it for sure. overall great product! its all i need if the power goes out. its even wife friendly.

Nice Generator

This is a great generator as long as you keep the battery fully charged. 1. Keep the generator battery charged. It will not pull start with a dead battery. Use the battery charged that comes with the generator. 2. If you can't keep the generator on the charger install a battery disconnect between the battery cable and the battery. My battery would drain when sitting for 2 weeks or more. The switch solves the problem. I really like the generator..

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.

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.

Great features

Love the CO sense no worries about the possibility of CO poisoning. The electronic push start lessens the hassle of pull start. Parts list could’ve been a little bit better detailed and the directions for installing the feet using the bolts and bolts for handle could be a little bit better but all in all everything was put together in about 15 minutes. I think instead of using cotter pins to secure the wheel pins I’d rather use a nylon locking nut.
