Overall excellent product

I recently installed a power inlet box to my breaker panel and purchased this generator to to power the house in case of a power outage. I have tested it a couple times now and it works great. Electric start would be nice but its really not needed. This generator is easy to pull start and starts on the 1st pull every time.

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.

Excellent Performance!!!

The RS8000E is a fantastic portable generator that performed admirably for 66+ hrs during a recent 72-hr power outage. I bought mine at the big hardware store that starts with the letter "M" and it was one of the last 2 they still had available. . It easily powered a fridge/freezer, 5 cu ft chest freezer, 1000 watt microwave oven, 8000 BTU window A/C unit, 5000 BTU window A/C unit, a mini-fridge, fish tank with heater/filter/bubbler, and several lamps with low-wattage LED bulbs. We took turns running the A/C units, never running both at the same time. My daughter even ran a hair dryer for a few minutes. The lamps never flickered, indicating that the RS8000E never struggled to keep everything powered. . The generator started up on the first pull every time in between gas tank fill-ups, which were less frequent than I thought they'd be. I was able to run it for 12-14 hrs in between gas fill-ups. . This generator is quite loud because it's so powerful, but we were able to run it overnight because our neighbors' houses are far enough away and they wouldn't be bothered by the noise. . I really like the convenience of the PowerDial, which eliminates the need to flip a choke lever, turn a fuel valve, and push the "On" button before pulling the cord like most other generators require you to do. . I highly recommend this workhorse of a generator. It saved us about $1,000 in frozen meat/food that would have spoiled, prevented our fish from dying, and kept us out of the dark for 3 nights. It paid for itself in its first use. . As a Wisconsinite, Generac is the first name that comes to mind when I think of whole-house and portable generators. You can't go wrong with Generac generators. So if you're thinking of buying the RS8000E, just go ahead and buy it! You won't regret it!

Stable Power

I purchased two Generac portable generators. This one is the GP3600. It has been an excellent unit. We are off grid and use our generators to supply power to our homes. The GP3600 is capable of running a standard household refrigerator, microwave, and ice maker simultaneously as well as miscellaneous electronics like a modem and computers. It also handles power tools like worm drive saws, drill press, wood splitter, etc. I will definitely be purchasing another unit similar to this one.

Post Hurricane Irma life saver

My brother in law let us use his generator for a few days after we lost power during Hurricane Irma. After 5 days without power, I bought this Generac unit at home depot and it has made living without power palatable. I was very impressed with the features provided -- the hour meter and service schedule by hours; the electronic start; the 8 gallon tank; and a bunch of other benefits not found on the other units on my street.

GP17500E

Generator does a great job. I owned one for many many years. I live in the country.We have very hard winters and that means power outages. The outages usually last many many hours.The Generac 17500 provides me peace of mind in a power outage. I don't have too worry about frozen pipes, heat, lights or food going too waste. I wouldn't be without my Generac. My original 17500 is getting old and this new one is the replacement/backup.

Excellent product and dealer service

Dealer made purchase very easy, put generator together while I waited and showed full operation of the equipment. Product is heavy but easy to move, gas shut off makes it easy to relocate the equipment without flooding the carb and smelling up the SUV.

Changing of the guard

We have been running our old 15KW Generac Guardian Ultra-source gasoline generator for the past decade to power our home during after hurricane power outages. The Generac has always been dependable. ( Be on notice however, if there are huge amounts of ethanol in gasoline, the unit WILL NOT RUN. A thing that may or may not be an issue after a hurricane ). We only run non-ethanol as a standard with fuel treatment, bolster your reserves. With standard maintenance (oil, plugs, filters,battery,,,) and running for 30 minutes+ every month, it has aways been “at the ready”. After 10 years, we are pulling the 15KW from service to rebuild the unit and it will be a backup. The 15KW would run 1 of 2 Central Vac systems, the heavy amp draw well pump, kitchen, home theater, lights, water heater, etc,,. Naturally we can shut subsystems off to conserve fuel. We do have our property in the swamps of Florida, 2 miles from the main road, so we are the last place where propane will be delivered after an event of a hurricane or other crazy events, that is why we chose gasoline. We purchased the new Generac 17500 and was delivered yesterday. At unboxing, we realized that the wheel axle was missing. Fortunately we had our existing 15KW and we had a working axel to maneuver the new 17.5 Generac through the landscaping into position. I thought, “here we go!”. I called Generac Support the next morning and “Bam”! The support rep was an English Speaking American in the States (Chris) and the part is on its way,,, UPS! 15 minutes of may time, done! Wow! It’s a bummer that my new purchase was missing a part, but I am surprised at the quick phone pickup with a fix! We will see how the new Generac performs, as it is expected to a active hurricane summer in Florida, The El’Nino weather effect is drifting away again.

GREAT PRODUCT

OK LET ME START OUT WITH MY DISCLAIMER, I JUST GOT THIS AND RAN IT FOR A LITTLE WHILE AFTER SETTING IT UP SO I CANT SAY MUCH ON THE LONG HAUL. FIRST IF YOU BUY THIS BEAST, DRIVE DOWN TO HARBOR FREIGHT AND PICK UP A CHEAP SHOP CRANE, I PAID $129 FOR MINE. THE UNIT HAS A LIFTING EYE ON TOP AND WITH THE SHOP CRANE I CAN EASILY PUT IT IN MY TRUCK OR ON A TRAILER. AND I ALSO LET IT HANG WHILE I INSTALLED THE WHEEL KIT AND FOOT. THIS THING IS PUT TOGETHER NICELY AND ALSO COMES WITH THE MAINTENANCE KIT FOR YOUR NEXT AIRFILTER AND OILFILTER CHANGE AND THE INITIAL OIL IS INCLUDED ALONG WITH CHARGING CABLES FOR THE BATTERY. I BOUGHT THIS AS A BACK UP FOR MY HOME HOWEVER IF ANY FRIENDS OR RELATIVES NEED IT AFTER MY POWER IS BACK ON IT WILL BE OFF TO THERE HOUSE. MY HOME HAS A WELL PUMP, ELECTRIC RANGE, HOT WATER, SEWAGE EJECTION PUMP, ETC, ITS ALL ELECTRIC, SO IF THE POWER GOES OUT WE HAVE NOTHING.

Worked perfectly when we had a power outage on Christmas Day.

We bought this generator because of 3 day power outage we suffered through this past summer. We lost power on Christmas Day and the generator did all we expected and more. It ran 2 refrigerators, stand up freezer, and furnace. We had heat, tv, lights, garage door opener ,coffee maker and everything else we needed. Ran for over 12 hours on a tank of gas. I would recommend this product to anyone, just make sure you have the correct size for you needs.
