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.

This is the BEST product I was able to find in this price range!

I am so happy with my purchase! I never thought I would get a Generac brand generator large enough to run my whole house for so little cash. What a value and it is loaded with features and setting it up took less than 20 minutes. And a bonus was how easy it is to move and transport so if I wish to do some camping in a state or national forest I can have power to go for my fifth wheel. Love IT!!!!!

Better then my first Generac

I already owned a 5kv Generac and was extremely happy with it. A few weeks ago my daughter lost power due to storms and was told it could be 5 days until power returned. I loaded my 5kw on trailer and connected to power her frig, furnace, and a few lights. Generator worked great as always, and saved all food, kept house heated. I then decided why haul back and forth, since it worked so well at her house I'd leave it there and buy myself this new 6500E. Now I know we both will never be w/o power again what ever mother nature throws at us and I will not have to "share."

Lots of Power for a Compact Unit

I bought this unit to replace a larger generator two years ago. It went through on hurricane like a champ. One half of my home was easily powered (which was more than enough, 1 AC 3 yard pumps, misc. 20 A breakers). The unit stores easily when not in use and is easy to move to hook up the transfer switch. I recently had a bad battery and the folks at Generac are replacing it. What a pleasant surprise and a guarantee that I will buy another Generac when the time comes.

A very well-built machine

The last hurricane that grazed central South Carolina sent everyone running to the generator stores. We live in the country with a well, horses and an aging mother living in the guest house. I bought an off-brand 7000w unit then the same day bought the Generac. I could see the engineering quality as I was readying it for its first start. We lost power, hooked up the Generac and forgot about the storm. Very, Very loud machine but it performed flawlessly. Never took the other off-brand unit out of its box so I returned it. We're buying a second Generac 8000e for our small business.

Satisfied so far

We have all our permanent electrical work complete (wiring, lockout, receptacle, etc.) and are ready for an extended outage. Recent -30F temps and some local power outages got me concerned since all my heat sources need some electrical energy. Of course I hope to never have to use the generator. The unit looks good to me and the setup was simple. I'm debating whether to fuel and start the unit knowing I then should run it once a month to avoid fuel problems.

Just what i expected!

I always do a major investigation before i purchase anything expensive.Sometimes it takes me weeks.I read everything including reviews.Finally after days of asking questions and reading many reviews i felt the Genarac GP6500 was right for me.I was right.Assembly was easy and took about 15 mins.Filled it with the oil that was provided and it started in two pulls.The unit was powerful enough to power up my whole house except the clothes dryer and electric oven.No more freezing in the winter or sitting in the dark.It is relativley quit and ran about 10 hrs on a tank of gas.I am very satisfied with my purchase and you can't beat the quality of Genarac.

This unit meets all of my expectations so far

I purchased this unit to replace an older smaller unit. It runs quiet for its size, and the large fuel tank means I don't have to fill up in the middle of the night. It is installed in such a way that I can feed the entire 200AMP Panel, and choose which circuits I want to power. I used it during our last snow storm, and put 14 Hrs on it of continuous use other than to shut down to fill it once. I am able to run my furnace, Well pump, Sewer pump, upright freezer, 20Cu ft refrigerator, 1.5 Cu Ft refrigerator, one light in each of the 3 bedrooms, a light in the living room, and a cable box & flat screen TV, and night lights in the bathrooms. If you have children, you understand the need for the TV and night lights! I usually leave about 10 circuits powered on, and monitor what is used on each circuit. Do you homework, figure out your wattage draw, and you will have no problems. Just be sure to balance your load draw. I chose the Generac because of their products are built well, and have a great track record. Best investment by far to keep a "happy family" when the power goes out.

Solid performer after fixing battery issue.

Solid performer after fixing battery issue. The battery died after 6 months and would not hold a charge. After installing a new battery and a disconnect so the battery no longer had a drain on it, I also installed a motorcycle style trickle charger. It now works perfectly and the battery holds a charge. I keep the battery disconnected until it's time to use it. It is now a perfect generator after the $50 upgrade. Too bad Generac did make the improvements in the factory because it does take a certain amount of expertise and engineering to correct the problem but is doable if you have the right tools. I will attach some photos at a later date.

Great product

[This review was collected as part of a promotion.] Overall we have loved having this generator around. We did test it out with a few power tools and it works great. We have it ready to go for the rest of hurricane season. Right now we have used it for minor stuff just to test it out and so far it seems to hold up great. It is not overly loud for a generator. I will say it is really heavy and I am glad it has the handle to push/pull it. I am even more glad its handle can be moved in different positions.
