I purchased the GP7500E to replace a smaller 3250 generator to provide backup power for my house. Last December we had a power outage in the middle of a winter storm, the smaller generator worked for a few items, but I wanted to power more circuits in the house. I installed a transfer switch so I can power the furnace, refrigerator, TV, computer and several lights in the house I assembled the generator, added oil, gas and connected the battery. It fired up right away! I definitely like the battery start! I did a test run on the house and everything powered up as expected, now to wait for the next power outage.

Missing parts out of the box. Cannot put the unit together properly. Will try to contact the company after the weekend. Would love to be able to move this unit from where it was delivered but cannot install the wheels without the axle. I hope this isn't what the rest of my experiences are going to be like.

This generator has it all. Electric start, hour meter, circuit breaker switch. So I was a bit surprised it did not have automatic idle. I might be wrong but it seems to run full blast 24/7. If I am mistaken please let me know. Apart from that feature, the generator runs fantastic. A bit loud but I can live with that. For thhe power rating I'm happy.

[This review was collected as part of a promotion.] Overall we have loved having this generator around. We did test it out with a few power tools and it works great. We have it ready to go for the rest of hurricane season. Right now we have used it for minor stuff just to test it out and so far it seems to hold up great. It is not overly loud for a generator. I will say it is really heavy and I am glad it has the handle to push/pull it. I am even more glad its handle can be moved in different positions.

I bought one of these about two years ago. It ran fine for 40 minutes the first time we used it. The generator had plenty of power and was reasonably quiet. The appearance and quality of construction appear to be much better than other similar size generators. For the next few months the generator was taken out, started and run a few times for testing. The next time we actually needed it, the generator ran for about 5 minutes and quit with a CO sensor alarm light on. The generator was outside, under a deck, but not enclosed in any way. Exhaust was pointed away from the house. We couldn't get it to run any more for that outage. It only has 1.4 hours on the meter, cranks good, but will not fire. Since then, I've dragged it outside, gone through the manual and tried several times to get it to run. It has plenty of oil and gasoline. It cranks good but has no spark, won't fire. I've looked, but have not found any place in the area that appears capable of servicing this generator. I suspect the CO sense system is defective, but since I can't find a reliable place for service, the generator and any warranty are completely useless.

I have used one of these for a back up generator for my house for 5 years and it does a great job, but I have recently purchased and installed a stand by unit 22kw which is awesome., There are a few things that you need to know before purchasing this unit, it is heavy and I have to use a tractor to haul it from my storage shed to the meter to hook it up, also if it is raining I have to wait until the rain slows down because the connections are open to the elements. the only other thing that pushed me to get a stand by is this unit is really loud. I think if you know these things up front and are ok with them then this unit does a really great job providing constant power when in use.

I had been shopping for a generator for 6 months, could not take the buying step. My wife consulted my nephew who said generac was best. Christmas a.m. was I surprised. Took 20 minutes to assemble, fill the oil sump, hit start and it ran like a top. What a relief to have back-up power if needed. excellent warranty, easy to move, happy with my Christmas gift.

Bought this unit to get us through the storm last year. It did it's job well for the first 50 hours, then it quite running. It won't start and run. Pretty sure it's the electronics, the CO2 sensor. Saw a U tube video of the exact model doing the exact thing. Bad unnecessary CO2 sensor. So it sits there broken waiting for me to find a shop, time, and help to load it.

I got this one to replace my older model Generac which needs service- 15 years old and still running well. This new one is just as reliable and started up right away the first time I used it. I use it weekly to pump well water and also use it for my house as a back up power source (off-grid). I researched for months before deciding on this generator and it has been everything that I needed and expected. Works great and I highly recommend it!

I love my new Generac generator. It is exactly what I wanted and my wife bought it for me for Christmas. Great features and great performance. I considered other products, but none had all that I was looking for except the 17500E. So I wasn't going to settle for almost .... bought the best and got everything I wanted !!
