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.

I love the stability of the Generac's power supply and the convience of the electric start.

During the ice storm of 2013 our areas' power was out for 8 days. I borrowed my brothers Generac4500 and was impressed with it's ability to supply power for services of our rural property. When you are in the country and you loose power it includes you water supply and with horses it was essential that we had a constant and dependable power supply for this period. We have since purchased a Generac7500 with electric start and it is able to supply stable power for our whole house. We have used it recently when the power was out for a day and we never missed a beat.

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.

Product assembles easily and generator started on first cord pull, but then...

I have rated the quality of this generator only "Fair" (a little below average) because of the two items that follow. The GP3600 generator is easy to assemble and it started on the first pull of the recoil cord. However, I ran into problems when I plugged in an electrical device: There was no power from any of the four 120 VAC, 20 amp, duplex receptacles (note: these receptacles have their own 20 amp circuit breakers). I had to call the store I bought it from and speak to someone who knows the generator and troubleshoot it with him. The problem was that the circuit breaker next to the single, circular 120 VAC, 30 amp receptacle needed to be moved from the "OFF" to the "ON" position. Once I flipped that switch there was power to all outlets. I did not know, and unless I missed it, there was nothing in the manual stating that the 30 Amp breaker controlled power to ALL outlets. There was nothing in the manual's startup procedure about this 30 amp breaker needing to be switched to "ON" so that power would flow to ALL outlets. I would recommend such a basic necessary item be addressed clearly in the manual. One other minor item: The plastic, zip-loc-type bags that the manual and warranty came in were very light grade plastic. I usually store the manuals for all of my power tools in the zip-loc-type bags they come in right in my shop near the tools themselves. So it would be nice if the bags were a little heavier grade plastic.

Powers almost whole house!

I researched a host of generators before deciding on the Generac GP6500. For me the Generac brand was the deciding factor and the GP6500 was the largest wattage I could fit into my budget. It was shipped promptly and arrived without so much as a scratch on the box. Assembly was quick and easy. Had a transfer switch(6 breaker) installed and everything in the house is usable except central air and washer and dryer. The generator started up on second pull and roared like a lion but powered everything I wanted it to power with room for more. I couldn't be happier. Almost looking forward to the next power outtage because I am ready for it now. I have not seen anything on this generator that is not well built and ready to last for a long time.

Solid unit

strong runner, love that it runs diesel. fuel tank is large enough to keep it running for a VERY long time, especially at lighter loads. my only gripe is the pullstart. i would be willing to bet that Paul Bunyan himself would not be able to pull start this generator. Make sure the battery is charged.

BEST ON THE MARKET

i have owned this for a few years now. have 93 hrs. on it does a wonderful job when needed. the only thing is the battery for electric start had to replace it (sits more then it runs). when the power goes off nice to have this. we lose power at least once a week ( BAD electric company).BUY Generac if you want to be happy when power goes off!!!!!

The gas on/off switch is not well illustrated on machine or in manual

I just bought a GP8000E, so I'm just getting familiar with it. I did buy it through a support company that will be maintaining it for me. So far, my one suggestion would be to clearly mark the gas on/off switch. It's not clearly marked on the machine. The company did add a green marker for "on," but none for "off." The sticker you have on it does not help at all. I had to call my support company to find out that when the switch is set to noon and 6, the gas is on, and when set to 9 and 3, the gas is off. The manual does not illustrate this very well, either.

This is the one!

I bought this unit because I am building a house in the country. Com Ed won't have power there for another month. It took all of 10 minutes to put this together. total 15 minutes from box to running. Loaded it on the 1st start, Wow, this will run everything I need it to. Then after the house is built, it will serve as a back up in power outages. Illinois doesn't have the best of winters out here in the country. I recomend this to any one serious about a quality generator!
