Excellent Generator

Generac makes a quality product at an affordable price; plus I prefer to support American made products. I bought this model on sale for $800. In the past 15 months, I've only put 75 hours on this unit to date (although it ran for 72 hours recently with several cooling/fueling/oil check breaks - at 40 hours, I hadn't burned a drop of oil but I did the first oil change). Basic maintenance is simple enough for anybody to perform. The GP8000E feeds my main panel and powers everything I demand in my house, such as my pellet stove, electric range, well pump, lights, microwave, outlets and TV. I haven't tried powering my hot water heater but at 5,500 watts, I think it would do just fine if I shut some stuff off. It sits approximately 20 feet from my bedroom; the noise is barely noticeable when I am laying in bed. I do ensure that my carbon monoxide detectors are on whenever I have this unit powering my house. It's much more fuel efficient than I expected, averaging around 2 hours per gallon of fuel. With all of this being said, I do hear a bit of occasional surging once the temperature hits 25 degrees or below but it has no performance issues. In my opinion, portable gas powered generators are the way to go for powering a house during an emergency. Natural gas isn't an option in my area so we are limited to propane; getting a propane delivery after being without power for a week isn't always an option!

bring on the hurricanes!

[This review was collected as part of a promotion.] Last year we ended up without power for well over a week due to Irma. This hurricane season I am so very thankful out family is covered with for power failure! This is a large generator but very portable and powerful! It's very easy to use and well built! I also can't wait to put it to use on an upcoming camping trip we have planned in the mountains!

The 7500E has everything you could want.

I waited a long time to buy the right generator and the Generac 7500E was what I was looking for. I could go on and on about the 7500E. It has everythng anyone could want in a portable stand-by generator. I am very pleased and would recommend this product to anyone looking for a quality generator.

Wow! This generator really cranks out the power!

[This review was collected as part of a promotion.] We use a generator to power our tailgate parties at football games. The person who normally brings the generator had his stolen so this is perfect timing! We tested it out and it has plenty of oomph to power the TV, satellite dish, mini air conditioner and various heating and cooking items we need it to. Not only that, but living in a hurricane prone area this will be a lifesaver when the power is invariably knocked out! It's not as noisy as I expected either! Yay!!

I would change nothing about this system

I bought this system to replace a 5000watt coleman unit. The coleman treated me well but this guy is incredible. I should should have purchase this a long time ago. It got our farm through 3 days without power in comfort. no having to remember what pump or appliance is connected. It does like gasoline so make sure you have plenty.

Reliable power.

Purchased the E7500 in 2015 during a week long power outage from a wind storm. It powered my furnace, lights, microwave, Keurig and toaster oven. It was 11 degrees F and very windy. I have used it several times since for minor projects. It starts every time with both battery and pull cord. It's on its second spark plug and battery. Love this generator.

Time will tell.

Recieved from fed Ex in great shape, no dings or dents. Simple, straight-forward minimal assembly. Pressed electric start button and starter only spun, NOT engaging the flywheel. Pulled hand starter once and fire right up. Put included battery charger on. Next day tried electric starter and no issues, so battery needed 'topping off' even though sent as 'charged'. Battery seems a bit small for this size engine. My lawn tractor has a bigger batter for the same HP. This is going to be a covered, outside unit and it will be seeing and starting in below freezing temps. Will be interesting. Will be kept on the battery charger

Saved our Christmas!

We were in the Michigan Ice Storm of December 22, 2013. Our yard looked like a war zone when it was over, trees pulled our power lines to the ground. I bought this generator on Monday the 23rd and got it running and hooked up to my fridge, freezer and furnace and several lights in no time at all, very easy to set up and run. It ran flawlessly for four whole days and nights, it would run 12-14 hours on a tank of gas. So glad I bought this, we enjoyed our Christmas with family, even though we did not have power to our house. Buy this generator, it will run your whole house!

Gets the job done

Great quality for those times of need. Electric start is great for the wives and the whole machine is pretty manageable. Bought Generac for the reputation of quality and support. The gas tank could be designed better to deal with spills. Otherwise its a great generator.
