Best 15,000 watt generator for the price

I looked all over and this is deffinetly the best generator for the money. You won't find a generator of this quality at a lower price. Took about 10 minutes to put everything together and I had the generator running in no time. The extra oil filter and air filter are a nice touch. Very pleased with my purchase. I expect this generator to give me many years of service and peace of mind.

GP15500 EFI *DISAPPOINTED *

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.

Great product

[This review was collected as part of a promotion.] I’m not sure why but our area is known for frequent power outages. This generator has helped during those times. It was easy to set up and use. Started within the first few pulls. Would definitely purchase again.

Awsome power and reliability!

Great portable unit! I bought it after hurricane Irene to run a Franklin Electric 3 HP well pump. I was without power for 6 days during the freak October snow storm here in the north east. It ran my well, heat (circulated hot water) and two fridges; I was also able to cook and do laundry (not all at once)! Survived the 6 day outage with little worry or pain. My only warning is that this unit is heavy (to be expected) and uses a LOT of gasoline so lots of trips to the gas station. I'm currently looking into a Guardian Series 20KW natural gas model with a permenant hookup. They make a great product!

great generator

Great generator for the price! easy set up. It also will be easy to maintain.Easy to start. just to see what i could run with it i put it through its paces. I ran 5 lights, 2 fans, 3 electric heaters, well pump, refrigerator, freezer, heat lamp, garage door opener. it ran all of it without any problem. I was bold enough to run all the above and turn on the hot water tank. now thats when the generator knew it had a load on it for sure. overall great product! its all i need if the power goes out. its even wife friendly.

Great value

I am a female, own a home and needed a generator I could handle in an emergency. I am able to move this generator, fill it and start it with no problems. It is reasonably quiet. It runs for a significant length of time without needing a refill (+/- 6 hours). During a weeklong power outage during a tropical storm, it kept my refrigerator on, my sump pump going, some lights on and I was able to charge my cell phone. It did everything I needed.

Good quality machine, runs great.

Assembly was easy and straight forward. Serviced it with gas & oil and connected the battery. Opened the fuel valve and hit the start button. It started on the first crank. Ckecking the outlets with a meter I noticed it ran quiter than I expected. Everything was right on the money. Too bad I didn't own it in time for the 2013 Christmas ice storm. I was a contruction tradesmen for forty years. I know and appreciate using quality tools.

Generac is #1

Gererac was my first choice, spent a lot of dark days before I purchased the GP6500E. Plenty of features, easy setup. I chose this model especially for the Electric Start feature, and the efficient fuel consumption rate. I also matched this generator with the Generac Transfer Switch kit.

I'm pleased overall with the features and output.

I was surprised that the THD was high enough that my digital frequency meter would not read 60 Hertz either at no load or full load. I had to read the frequency with my ocilloscope. However the THD must be low enough so that it doesn't seem to bother my electronics. It starts easy with the pull starter. I'll probably use a bigger starting battery when the little one that came with the unit dies. The voltage is pretty stable during motor starts. Since the genset is heavy I would like to see a lifting eye to set it in a pickup bed. All things considered, it seems worth the affordable price for an 8 KW non commercial machine.
