Rated 5 out of 5 by Has everything I need! This is an excellent generator for the price. Starting with the person that took my order, he answered every question I had and it took no time at all to get it ordered with a delivery date that was met! Assembly was a snap. It took no time at all! I put 4x4's under the frame then installed the axle brackets and the axle. The tires were just a bit wider than the pallet, so once the tires were installed, all I did was roll the generator off the pallet! It started up easily and all plugs put out the voltage that was labeled! I took it to my deer camp and ran the cabin without a hitch! It is a slight bit noisy, but if I have a choice of noise or no electricity, I will take the noise any time!! I have not run my house with it yet, but that is coming up soon. Living on the gulf coast, you never know when a hurricane will come in on you and I will be prepared!! At this point, I give this generator an A++ rating! Once I run the house on it, I will give an update! July 30, 2014
Rated 5 out of 5 by GP 15000 = great generator Ordered this generator on-line for store pickup. It is a beast as you can imagine. Used an engine hoist to unload out of the pickup and install the wheel kit. I added oil and put 5 gal. gas in the tank. The engine started right up. Wired in a new Reliance 200 amp generator transfer panel and reliance 50 amp inlet box for the new generator. Plugged it in and switched from utility power to generator at the main breaker. This generator will power everything including the heat pump without even groaning. Very happy with this product. September 2, 2014
Rated 5 out of 5 by Outstanding Product The generator arrived in perfect condition. The packaging was outstanding. It took about 20 minutes from the time it was it was uncrated until it was running. It was connected to my 2100 square foot home and it ran the whole house. That included a 5 ton AC, electric clothes dryer, lights, ceiling fans, chest freezer, refrigerator, water well pump and TV's..................the whole house. It never "bogged" down or missed a beat. Noise is moderate....but with doors and windows closed with the TV on I never noticed it. It came with an extra air filter, fuel filter, some Sta-Bil fuel treatment and 2 spark plugs which I thought was a very nice touch. It is heavy but well balanced and easy to move about. Great product for a reasonable price. March 5, 2013

Rated 1 out of 5 by Generac 15kw generator Used it for the first time on 12 Feb 2014 during the ice storm here in Summerville, SC. It operated for less than 2 hours before the engine threw a rod. YES, it had OIL in it. Though out of warranty, contacted Generac by email...still waiting for reply. Hoping for a "good gesture" on their part. February 16, 2014
