Love the features!

[This review was collected as part of a promotion.] Last year when a hurricane hit we were without power for 3 days. I said then that I would not want to go through that experience again without a generator. I was worried that we would lose all of our food in our refrigerators as well as our freezers and that would be devastating for us. For years I have heard that people had problems with carbon monoxide issues with generators so I was so happy that this one is equipped with CO Sense. I feel safer using this with my family. This generator has an electric start so it is even easy for me to start. I am thankful that I do not have to worry anymore about what we would do without power. In the long run this will save us a lot of patience and money since we will be able to run our refrigerators and freezers.

It's a great generator but.....

I bought this GP8000E to replace an older other brand with lesser capacity. It starts instantly and performs wonderfully but on day two I moved it on my trailer and after it had experienced a few bumps on the road I discovered that the fragile welds on the axle brackets had broken and bent on both sides. To properly weld them the unit had to be laid on each side resulting in oil spill etc. It was disappointing to see a unit with so much quality in other areas to fail on something so simple.

Great generator, lots of capabilities

[This review was collected as part of a promotion.] Ive been through 15+ hurricanes and I can say that Ive used a lot of generators during those storms. This is definitely one of, if not, the best generator Ive owned. The crank is a little hard to pull at first but the operation and output is tremendous. Lots of additional outlets and the ease of adding fuel (with the tank being centered on top) makes this a great find.

DIDN'T FIRE UP ON IT'S MAIDEN VOYAGE DESPITE FOLLOWING DIRECTIONS

DIDN'T FIRE UP ON IT'S MAIDEN VOYAGE DESPITE FOLLOWING DIRECTIONS. WAS HARD TO LOCATE A UNIT DURING THE PANDEMIC AND HAD TO TRAVEL 4 HOURS ROUND TRIP TO GET IT. BOUGHT IT, THOROUGHLY READ THE MANUAL, DID EVERYTHING TO THE "T" OF RUNNING NON ETHANOL GAS, HOOKING IT UP TO TRICKLE CHARGER, ETC ETC. I TEST RAN IT EVERY WEEK. LAST NIGHT WE GOT HIT WITH A 2 FOOT PLUS STORM AND SHE DIDN'T FIRE. VERY, VERY VERY VERY VERY UNHAPPY AND NOT WHAT I EXPECT FROM GENERAC. SHAME ON YOU. I EXPECT A CALL FROM GENERAC INFORMING ME HOW THEY ARE GOING TO MAKE THIS RIGHT. THANKS.

Good choice for Back Up

I did my research and purchased this to replace my Husky 5500. It is a bit louder but was expected. Still quieter than most brands. Built very stable and comes with most important features. I hook it up to a transfer switch and powers most of the house. Starts fast and runs smooth. Looks like it will give me years of satisfaction. Very nice generator.

Ease of setup and operation

After delivery, the Generac 7000 was easy to prepare for operation, easy to start ( electric start). Our house has transfer switches ( 6) and with our electrician we tested the system and the 7000 to make sure all was running in order. Everything was perfect the first time. I recommend having an electrician go over everything, especially with the built-in transfer switches. The peace of mind living here in Maine, that we can have heat, refrigeration, lights and some comforts is reassuring, especially if the power goes out. This will probably lead to the purchase and installation of a stand-by unit down the road. Thanks for building a safe, easy-to-operate, sensible power source in case of outages which can happen especially here in Maine. I like my comfort and this is real, real PEACE OF MIND.

A Work Horse

We purschased this generator back in first days of October, after huriacane Maria hit our island in Puerto Rico. Worked more than 10 hours nightly cause power went out in my house from September 20 and came back Novemeber 20. Worth every dollar we paid, if you do the maintanience punctually you"ll get the best of him. We are firts time buyers and we recomend Generac to friends. Pay for quality.

Super impressed

Was part of the "Bomb Cyclone" that hit the PNW on 11/19/24 and lost all power. After two days, we decided to invest in a generator knowing that this could happen again. The set-up was easy, the controls were well labeled, the starting process was explained with help from stickers located above the fuel line and choke lever (but make sure to read the manual first). The unit started with ease and ran for 4 days straight as we were out 6 days total. I was able to plug in the chest freezer, mini fridge, floor heater, lights, cable with TV, recliners, computer, and was also able to charge phones and flashlight batteries. This is my first generator ever and now wondering why we didn't purchase sooner. Would have made those first two days way more tolerabe! As a suggestion, even though the unit comes with a 20' heavy duty cord with 3-plug-in capabilities, I stronly suggest having a 50' or 100' equivalent heavy gauge (12g minimum suggested) to run from the unit into the house. If there was one thing I would try and change, it would be the noise output which I know accompanies all generators and just something you and the neighbors will have to deal with unless you devise something that dappens the noise without hindering the exhaust in any way. Overall, I'm super impressed and would recommend to family and friends without hesitation.

Works well; good warranty

I bought this product brand new after our home was impacted by Hurricane Helene. The generator worked great, but the fuel gauge was defective, causing a lot of undue stress and complications. It has since been fixed under warranty, but it was not something I thought I would have to deal with.

Easy to use / Easy to set up

I had been looking at a generator for awhile and contemplated many different brands. For the price, wattage and most importantly, name brand quality, I found that Generac was the way to go. Spend the money and get the electric start. Save yourself the aggravation at using a pull start. Just push a button and rock n' roll. Upon first unboxing it, everything was zip tied together very neatly and it was well packaged. It wasn't so overdone that you spend hours cutting away zip ties like you do with your kids toys on Christmas morning. Cut a few of the zip ties and you are ready to connect the batter cables. The generator was SUPER easy to get set up. If you can use a wrench or socket set, then you are good to go. You don't have to be super handy at all to do it. The directions were very simple and easy to follow. A matter of securing the wheels to the frame with the axle and washers (Provided) and also securing the pulling handle to the frame. Other than connecting these bolts and two very small bolts for the batter connection, it was a snap and took only minutes to unbox and be fully ready to use. The generator comes with an initial package of oil and it's a matter of opening up the oil valve and pouring it in. Heck, I can do that. This unit is very heavy. So if you plan on wheeling it around your house, or you have an outlet on a further away side of your house, just remember that you may be trudging it through feet of snow, like I do in Maine. So just have a plan in place to have it put somewhere for awhile or the ability to wheel it around with ease. Overall, the generator just looks cool. The black and orange color is cool looking. Obviously not a requirement and individual tastes vary, but it looks like a well built machine and the colors pop. The Generac name is why I went with this one. From past experience of buying cheaper name "knockoffs" to save a few bucks, I have always had it come back to bite me. It's true that you get what you pay for. This unit was priced the same as the knockoffs, too... so why not go for quality, even if you pay just a tad more. But I was very pleased with the price point. LAST, and my ONLY complaint was that I thought the unit came with the L14-30R cord. It DOES NOT. So, if you plan on hooking it up to a 30amp power source, with the 4-prong outlet you will have to purchase the cord separate. Other than that, I am 100% please with the purchase and think you will be too. It powers everything in my house that I need.
