Product arrived on date as promised. Set up was pretty simple. Filling with oil was a little tricky, but not impossible. After filling with oil and gas pressed the electric start switch and it cranked right up. I'm having an electrician install the transfer switch in two days. He has the same generator and recommended the Generac brand, so that's what I went with. Seems like a well made product.

WE BOUGHT THIS GENERATOR AND THE LAST THING WE DID WAS PUT FUEL IN IT AND IT LEAKED ALL OVER THE PLACE. WE TRIED TAKING IT BACK TO THE STORE BUT THEY WOULDN'T ACCEPT IT BECAUSE IT ALREADY HAD FUEL AND OIL IN IT AND SAID WE HAD TO TAKE IT TO A SERVICE STORE. WE HADN'T HAD IT FOR ONE HOUR AND HAVE TO DO THAT OURSELVES. NOT SURE WHAT WE ARE GOING TO DO AT THIS POINT.

During Hurricane Sandy we were without Power for 13 days. My friend got power back in five days so he lent me his Generac GP 6500 and it powered my four bedroom house for 8 days without a problem running about 20 hours a day. So I went out and bought one for myself. My neighbors with bigger generators were very impressed with my little generator that could.

We was dealing with a major power outage, after looking at several other brands, I went with this brand and size, because everything I have heard, I trusted it. This unit was perfect, it provided power for my side by side fridge, and two upright freezers with plenty to spare. While others were sitting in the dark, we was sitting in a well lit living room eating supper. Love my new Generac generator.

I got this generator after Irma hit and I was with out power for 6 days. I got it set up and had a manual transfer switch put it so I can power my entire house. I tested it today and it will run my central AC with out even breathing hard. I have 1600 square feet under air. I have not tested it yet but am figuring it will run out central AC, fridge and freezer with out much of an issue (as long as they don’t kick on at the same time). As for the noise level, it’s not quite by any means but I have used much loader generators that were much loader. It has a very low tone that is tolerable. Over all, I am currently very pleased.

In order to run the entire house (4,000 square feet 5 bedrooms), I had a new panel installed in my house and bought the 1500E. Minimal assembly was required. Be aware this is a heavy generator, so you will need help unloading. Runs perfectly. The only issue was that it cut off unexpectedly during a test run and wouldn't do anything - turnover, etc. After referring to trouble shooting section, I checked the fuse - it was broken. Do your self a favor and buy some extra fuses... $2 can save you some headaches. Already have 80 hours on the unit after Hurricane Irene and this October 16" of snow we got in Jersey, so I am loving this generator. Two of my neighbors are buying the same unit after hanging out at my place.

This particular model has enough available power to run an average 3 bed room house including the furnace and refrigerator. To ensure a no overload condition have refrigerator turned off until furnace or ac kicks in then turn on. Easy to maintain and easy starting.

I bought this generator after researching online. Brand name carries a lot of weight in the generator field so I decided on a Generac and was not disappointed. Had the generator out of the box, set up, break in oil added and running in less than 30 minutes. One week after I brought it home we had the seasons first snowfall and the electricity went out. Hadn't had time to get the electrician to do the hookup to my service panel yet so I ran a drop cord in from outside and plugged in the TV. Watched television until the lights came back on in about an hour. Worked flawlessly and can't wait to see how it works running through the service panel. I would definitely recommend this product.

Ever since I bought this in May of 2014, I have yet to get it started using the battery. I can pull start it but my wife can't due to the fact it's pretty hard to pull start. Battery doesn't even turn over the motor even after a full charge. Called customer service today and they were helpful but now I have to bring to get it fixed at a authorized dealer.

I purchased and received my GP15500 EFI on July 11, 2023. I purchased the unit to supply supplemental power to my home, as we experience frequent multi-day power outages due to severe weather. As of yesterday, 07/29/23, we were subject to severe weather and lost power. I fired the generator up and started supplying power to my home. The unit worked flawlessly for 10 hours, getting me through the night. Woke up this morning, 07/30/23, and shut the unit down to let it cool before refueling. Went to get more fuel and when I returned home (30 mins later) I found that the top portion of the fuel tank imploded and collapsed on itself. I am in complete disbelief. This was supposed to be a reliable piece of equipment and at $4,000.00 I expected more. Yes, the unit is covered under warranty. However, no Generac certified repair shop is open on a Sunday and I estimate not having my equipment back for several weeks, figuring new parts will have to be ordered. The unit was assembled and maintained according to the manufacturer's manual (i.e, oil level, fresh fuel, proper storage, etc.) And only has 11.2 hours of run time. I went with Generac because of their exceptional reputation but now regret my purchase, as I have a $4,000.00 paper weight and no power. I may update this review once my equipment is repaired but fear I will run into the same issue in the future. I tried to add photos but I am unable to do so.
