I was very pleased with this product

The unpacking and assembly were well described and easy to complete with minimal mechanical skills. The engine started right up and power was immediately produced. I let the unit run for a few minutes and then checked the oil level and examined the unit for any leaks or other obvious issues but none were found. I would recommend this product to anyone in need of a large portable generator for emergency or other short term uses.

Ran twice.

Ran it 15 minutes when i bought it. It ran very well. Didn't have to use it this winter, thankfully. Ran it 3 days ago and the float was stuck in the carb, leaking fuel everywhere. I had put Stabil in it for storage. A little disappointed, but they fixed it under warranty. Overall runs the whole house with ease, so thumbs up. Just had a minor problem. Hope that is all that goes wrong with it.

Perfect for outages

[This review was collected as part of a promotion.] I absolutely love my Generac generator! It puts out when we are in need. It can run my entire house, lights, stove, refrigerator, and window units. It looks great and it's handle makes it easy to pull.

Simple/easy/user friendly

I just picked up this generator under the strong recommendation from an electrician. Fantastic advice. As mentioned above it is easy to use and laid out quite simple. I find it to be built solid and durable. I love the electric start feature as well as the pull start in the event the battery is too weak to crank the engine. Battery came charged when I received it and even though we had temps at -20 to -30 all month she still fired up quite easily. Highly recommend this generator.

Excellent value

Just got it. started perfectly without any issues. Easy to move around. Everything as advertised. Have not used it for power yet but have high expectations. Not nearly as noisy as i thought it would be. Not any louder than the poulan pro 6600 which it is replacing.

There are still great purchase experiences to be found.

From sturdy packaging and clear instructions to quality manufacturing and ease of use, nothing could make for a more satisfying purchasing experience. Thank you Generac Team for a clearly superior product. Pride in all aspects of your company is evident and appreciated. Joe

A portable beast

When I decided to purchase my generator, I spoke with a fellow instructor at the JATC. The company he works for is an authorized dealer of Generac and he understood my needs, as my home doesn't have natural gas nor a large propane tank. This generator is basically a whole house generator on wheels but uses gasoline. Assembly was rather easy with basic tools but a friend to help is recommended due to the weight of the unit. Speaking of weight, maneuvering is easy with the large pneumatic tires. Once the fuel system was primed it fires up a moment after the start toggle is pressed. The fuel tank is large, most small cars don't even hold 16 gallons, buy several 5 gallon cans as they are easier to lift/transport. As a licensed electrician I did the install myself and chose not to install a transfer switch but used a main breaker lock-out on my panel. As it sits the generator is not AUTO transfer switch ready but any good electrician could void your warranty and make it work...lol. For being all electric I have a light load of only 44A max per leg and the GP17500E doesn't even bat an eye. Summary.....have basic tools and a friend to help. Higher an electrician to install the proper legal hook-up means. Buy several gas can and rotate the fuel often. Very satisfied with everything.

Reliability!!!

I purchased this product after reviewing several manufacturers. I was looking for a size that could provide most of the convinces we are used to in the event of an outage. I have a Generic 4000XL that was good but not big enough. We had a six day outage due to a tornado that left most of the city without power. The 4000XL failed in the first five minutes due to a winding wire that got caught in the armature and shot the voltage regulator. This outage convinced me to double the size of the unit as it became a nuisance switching power cables. It would be great to be able to afford a standby natural gas unit but resources are tight. This unit performed very well!!! Even though it is battery start, it started easily manually and on the first pull!!!! Now I need to see if the 4000XL is repairable for smaller building projects that do not need lots of power.

What fuse?

My generator has a 3Amp fuse. Guess what? Generac does not show this fuse on their drawings. They can't tell me what it does nor where it is located on the unit. I had to send them a picture so they knew their own Generator design. One more note. 4 Generac Generators crapped out in my neighborhood during Hurricane Florence. That meant that 4 homes were without power for 7 days. Says a lot for Generac reliability and performance. I'll never make this mistake again.

Great Generator!!

I purchased this generator after doing some research and felt this to be the best generator by far for quality, features and price. I had used a John Deere that I paid almost 1500.00 dollars for after we were hit by a severe ice storm in 2003. The John Deere was junk compared to this Generac. The John Deere will not stay running if left in the rain or if snow blows in on it. Also the quality of the John Deere was cheap!! It had a plastic gas tank, no electric start or anything to keep it off the ground. The Generac comes with the electric start (which is great), wheel kit, a solid frame and a handle to move the generator around with. Shop around and compare you will end up buying the Generac!!
