this product, GP17500E, so works

After having our electrical disconnect professionally installed by the power company our Generac GP17500E, Provides power to our 5,800 square foot home without interruption. Just to give you little back ground as to what it operates is as follows: 5 ton heat and AC, well, for water, Three deep freezers, two kitchens, all lighting and electrical, etc... I can't get over how impressed I am how efficient the generator operates. The added bonus is that I can transport the generator and multi task with it as well. I also bought it due the great reviews for their warranty. Knock on wood I have not needed to use but its there. Love my Generac

Works great right out of the box

I was amazed on easy everything was and how well it was all explained. Setup took less than 10 minutes and you just have to fill with the oil supplied and fill with gas. Getting the gas took the longest time of the whole setup process. Started on the first pull and ran like a champ. It runs quiet and and with very little vibration. I purchased this unit because I am sick out power outages and this is the best investment made for that problem. It will run everything that is needed when your power goes out, to get you by without damage to your home or your pocketbook. Best Investment I ever made, don't know what took me so long to get one!

It is great!

Just bought this generator after much research on internet, different hardware stores, and electricians. The price is right and our local hardware took the time to gas it up, put in oil and give a demonstration in use. The noise level was certainly acceptable and less than expected after seeing some negative reviews elsewhere on the noise. The ease of portability, electric start as well as pull, and having not to buy wheel kit are extras. The unit started at first flipping of switch. Recommend it highly.

This generator is really nice and powerfull.

Live in northern Florida, city of Ocala out in horse country and our power grid goes down at least once a month and we also are affected by hurricanes. This generator will power your whole house if required, starts easy, runs quiet for its size. It's real heavy to move around but manageable, I am using the 30A and 50A outlets in tandem to feed my single home electrical panel because the single 50A only gives you 12KW of usable power.

Excellent product!

Ran generator for approx. 50 hrs. straight, except for re-fueling, during Hurricane Irene. It provided reliable power and saved us quite a bit of money by not having to replace food. Also provided comfort as it powered my central air conditioning with no trouble. Easy to set up and start. Acceptable noise level for size of unit. Does like gas!

Just what I was looking for

I was looking for a dependable generator for home back up for basics, fridge/freezer a few lights and possibly my TV. I was also looking for ease of start up. I am a woman and this generator is perfect. Easy to start and maintain. Everything I was looking for.

Love it!

Not my first experience with Generac products as I purchased a GP7000E in 2009. It still runs but I have outgrown it and the GP17500E will meet all of my needs for the several different uses I have it for. Excellent product, highly reliable and all of the people I have talked to that work at Generac and the people at the dealers have been absolutely a pleasure to deal with on every level. More companies need to follow Generac's lead with product quality, reliability, affordability and, above all, the quality of the people they hire to represent their company. Absolutely first rate, Generac! Well done!

great machine

This is a great machine. I purchased it to run my whole house in the event I need it. It is portable and large and heavy. I bought a small trailer to mount the generator onto for easily moving around, hook it to my truck or ATV. Trailer has room for the big power cord and other extension cords. I purchase a bigger interstate battery to start it. I also use the battery for other things.

Big enough for the job.

Shaky start with this machine. Dead battery out of the box and loose contacts in the outlets. Wheels adequate for concrete, but wish they were larger and fatter for moving through gravel. Starts easily. Noise is at 73 DB as stated. Factory Service center took care of the battery problem, but wasn't concerned about loose contacts in outlets. Duh. Sometimes no juice comes out of the 110v side. Have to fiddle with the plugs to make contact. Had a short power failure after purchasing and debugging the generator. Decided to wait for daylight before hooking up generator, but by then power was back on. Because of the garage door design, I will make a shed for the generator's outside storage next to the 220V receptacle. Secondary purpose for the generator is to power the community well in our plat, if needed; hence the need for wider tires when moving the generator through the gravel to the pump house. I think the generator is worth the cost, but am sorry the Factory quality control was sloppy. I wish the factory would actually run the machine and completely test it prior to shipping. A little odor in the gas tank at the store is a small price to pay for enhanced reliability. Nice to have features: a battery feedback circuit, and an output meter advising how much wattage is being drawn by the system being supported by the generator. Best advice I can offer to a buyer is buy the generator in June or July. I didn't get around to purchasing my generator until winter, and there was no selection available in two Counties. This machine was literally the only generator of this class available. I went looking for an 11,000 watt machine and had to settle for this 8,000 watt machine. I think it will run the pumphouse. Maybe I'll never have to find out.

Installed, but not put to the test - yet.

The generator started and ran immediately, looks like a substantial piece of machinery. We did have one short power outage where generator was put to use for a few hours, and it worked well. I overlooked the fact that the 120vac outlets are GFCI because they are solid black (reset/test buttons and face all same color, and my garage is dark), and the outlets were tripped. So, I initially called support reporting that those outlets were dead. Actually, they were OK. Incidentally, when I did call support, they did not think of that. I really wish there was a load meter. I just noticed today that the XP8000E has the load meter, but that model wasn't among those I found available when I shopped.
