A good emergency power source. Provides peace of mind knowing we will be ready for the next power outage.

I just purchased a GP7500E generator. Installing the wheels and handle was easy and after adding the included liter of oil and a little gasoline, it started up immediately when I hit the start switch. I shut it off and tried the recoil starter as well and it started right up. I tested it with a power saw and had no issues. It is a little load, but much better than my previous 4000 watt generator. I am glad to know if we lose power in the next storm, we will be able to keep the lights on, have water and heat and keep the sump pump running. It gives me peace of mind.

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.

DEAD unit & useless warranty

WORTHLESS. Unit will not start, presumably due to dead battery (as many others have said) that will not take/hold a charge. Generac said they would replace the battery under warranty but after 6 months and numerous phone calls, the replacement battery has yet to be shipped out from the manufacturer.

glad to have this

Good product, easy set up and install. Live in rural area and power sometimes goes out for a while, so always wanted this. Looking for an enclosure to buy so I can store it closer to outlet, not sure how it will pull through snow from garage. Started on first pull, hope it's always that easy to start.

Easy to use. Supplies sufficient power for my needs.

Bought the GP8000e for my ski cabin. It will run everything including well pump and hot water heater when we loose power which has become more frequent. Happy with my purchase. Decided to go with Generac since I already own a Generac generator for my primary home.

Outstanding generator and easy to use

After several power outages (ice, wind storms, etc.), I bought this generator after the recommendation of an electrician friend. He has one for his home, and he definitely made a great recommendation. While I was out of town one evening, all the power went out in the neighborhood. My 16-year old daughter was able to pull the generator out of the garage, run extension cords, and connect the refrigerator and two freezers. She had help from a friend, only because she had never used it before. We didn't lose any frozen or refrigerated items. Highly recommend this generator for home use!!!

We'll be ready next time!

We have lived in PA for year and half and have lost power twice for a week each time. We have done our research, and we are so pleased with the GENERAC 7500. Delivery was quick and easy, putting it together out of the box was quick and easy. Our electrician is installing an interlock into the circuit breaker box, so we will be trained and ready for the next "this never happens" storm that knocks out power. We are on a well, and have a sump pump. Having this generator gives us such relief in knowing we can still operate most of our home off the grid temporarily. Also, how cool that if we need to take it on a camping trip, we can load it into the truck and go! Awesome idea!

xt8500 efi is a very nice generator for the price

I'm a controls engineer who was very fussy about what kind of power that is going to my house. i know what kind of damage could happen if you get power spikes, power surge and transient voltage. all kind of the same thing. when testing what kind of power that came off of it seemed great. 60hz and 240volt RMS. I had zero problem with it. i do charge the battery every 90 days give or take. my only complaint that i have with it is i wanted a spine on oil filter. Generac said it had one, it's a fine screen not quit what i wanted. but it was already delivered so i keep it. One thing i would get for your house with any generator is a whole house surge protector.

Bad Bad Bad

F...ing garbage. Do not buy. Runs rough if it starts. Worst generator I've ever had. I would say used but can't hardly use it. Bought new. Was garbage right out of the box. Should have returned. Spen up and get a Honda. This thing is junk

Was able to get an outstanding deal on a slightly used, 0.4 hrs., 15000e.

I wired the generator up to the house and tested it out. Ran everything including a 3.5 ton AC. Now ready for the inevitable South Florida Hurricanes. Unit started right up after I replaced a 4 year old battery that was completely dead. One of my best purchases.
