Assembly was rather easy, unit started right up with the electrical start. Was disappointed that the unit does not have a load monitor that tells you how much of output is being used. This should be an important addition to the unit. The breaker switch technique just tells you when you have over loaded the unit.

My company purchased this generator at the recommendation of our electrician. We have a 20,000 sq ft facility (5k office, 15k warehouse). We looked into a 45-60kw standby generator but felt the cost was too high. We decided to try this unit with a manual transfer switch for our facility. One week after installation we lost power for 2 business days. This generator ran 2 HVAC office units, 6 modine gas heaters, 25 personal computers, 3 computer servers and related hardware, office telephone, fridge, half of the office and warehouse lights and more. If we could have hooked up the transfer switch to more of the breakers I think this unit would have powered almost the entire facility. It started and ran without skipping a beat. We spent a fraction of the price quoted for a built in standby unit. We would recommend this setup to any small business.

Only time will tell if it holds up well over the long haul, or if the investment was a poor decision. Realistically I don't believe it is meant for heavy duty service, but if taken good care of, and with only emergency duty, I will expect a long service life (many years) of reliable service.

I used my generator once up to this point. It powered my house for a day. It’s a duel fuel generator, I wanted to use the propane option, read and reread the manual numerous times, but could not get it to work. I used gas. In order to get it looked at I’d have to lift the generator into my suv, which is impossible. I feel it’s ridiculous that I can’t get someone to my house to look at it, get it working properly.

I have had this generator since February 2017, the peace of mind is priceless. I did look tirelessly and this model was the best value. It easily handles our home ( 4200 sq ft) multiple refrigerators and 2 central air units. I did have the electrician wire the house for takeover, much easier given the winters in New England. Easy install, unpack and setup, by myself. Best of all made in the USA, great network of service centers here as well. If you, like me are looking for an alternative portable power source, this is it

I purchased this in 2005 because of the hurricane Wilma, I live in Pompano Bch. FL. It has set in the garage for 12 years . I started it last year to check it and put it back. By the way it started right up no problem. Then along came Irma this year. I had pulled it out and got ready. I lost power Sunday and didn't get it back till the following Saturday. The generator ran flawless and I never shut it off. I kept the neighbors food. It ran my central ac, refrigerator, a wall ac,freezer,4 TVs,4 ceiling fans Water heater, pool pump, lights, microwave, boat lift and never stopped once. The best thing I've purchased. It sat along time but was there when I needed it. Thank you for a great product. My wife has 2 different forms of stage 4 cancer and we really needed this life saver. Wishing you all the best and hope we never need it again but if we do I know it will be there. Sincerely Pat

I highly recommend this generator to everyone. My GP7500E was easy to set up and get started right away. It will be nice when the power goes out here in south Arkansas again and I can just start up my generator and not miss a beat. This generator will do all we need to do. Thanks Generac.

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.

During the recent power outage caused by Hurricane Sandy we used our GP7500E to power our entire home through a transfer switch. Refridgerators ( 2) , sump pump, Fan for gas heat, lighting, bathrooms , TV, kitchen appliances all working no problem. Unit ran 12-15 hours a day for 7 days. Changed oil at 32 hours then every 50 hours after that. Great unit. Purchased unit during the summer and this was the first big tryout. It passed with flying colors.

This has saved my bacon 4 or 5 times. I almost wish for a storm to come now because I'm prepared. I hadn't used it for a year and I ran it yesterday as a test and it started up right away. It kinda scared twice though. The first time I ran it it burned almost a quart of oil. And then once I filled it up with gas and I hadn't turned the fuel shut off valve to off and somehow the some of the gasoline went into the crankshaft. They don't tell you that in the manual. And now the manual says paper air filter but mine is foam. But ,I still love it and chain it up when not in use.
