Received brand new just a few days ago, ahead of a big storm. It ran for five minutes and then died as soon as it got a little wet. Tried restarting, but it shuts down immediately every time. Throwing fault P1600, which nobody knows what it means. Generac L2 support is largely unhelpful and can only advise me to disconnect the battery (which did not fix anything). Let it dry out for an hour and it ran for another five minutes before dying. None of the local service centers have the time or experience to work on an EFI generator and will not service it. In New England, a failed generator can be life threatening. This will be my last Generac. Not reliable at all.

I bought this during the Bay Area power shut off and it's made my life a lot easier. It was easy to set up and it starts with ease. It's been running a bunch of things in my house with no problem. It ran about 10 hours on a tank of gas. My only criticism is that I wish it had a better muffler or some type of insulation as it's nosier than I thought it would be.

got this unit from local home depot for irene .only one i could find find from here to canada bolted on wheels added oil and gas fired up and ran with on problem for 6 days till power came back on. great back power for your home , i will tell all my friends to check it out ..

The generator was very easy to setup out of the box, with clear & concise instructions. Filling was easy as was connecting the ground wire. This is no small generator and has a lot of power, The pull start was easy to operate. It is not a quiet generator, by any means. So, it's not for going camping. We bought it to have as backup for the major appliances in our house. It has useful 220V connections as well as 110V.

I purchased this generator after purchasing and returning 3 Westinghouse generators. 2 generator was defective and the other 1 would not power what I needed. Purchased the generac and am very satisfied with its performance. No issues with this generator. Provides all the power I need for my camping needs.

We have extended a tailpipe 5 feet up from generator exhaust, it still senses the Co2 and shuts off, no help from Generac other than taking it to a mechanic and I know the problem is the sensor. This has only been started to test, sadly, we were past the 90 days to get a full refund, we bought in case of a storm related power outage. Very disappointed. Now I will unhook the CoSense and this will void the warranty. Hard to go out and restart every 10 minutes if being used post storm. It was advertised as built in US with 2 year warranty, tag states made in China.

We bought our 76861 to replace our 20yr. old Coleman Powermate which still runs well.This machine will let us run more necessary things, like our well pump and furnace, and with the transfer switch, not have to dance over extension cords.I got 4 different wheels and tires for it, so now it is simple and easy to move over our yard, and in and out of the garage, looks like an open wheel modified from 1970.It started on the first pull after I put a couple of gallons of VP110 in the tank.It will only get 110 or VP SEF to eat, as you can leave it in the machine with no problems.I hooked it up to the house today, and it never seemed to notice the load.It is heavy, strong, and well made.It is well worth my money and I am very happy., with it and the 6853 transfer switch.

Owned it 2 years. Refused to start on one of regular start up dates. Took to small engine repair. He got it started after changing spark plugs. Got it home and battery was dead. Refuses to start. Can't count on it when we have a power outage. Waste of money. Now having to look at getting a Honda.

bought this the day before the hurricane. Set up took about 20 minutes. Started right up and instructions were really easy to follow. Even came with a 20 ft 20 amp cord which was great since it was hard finding any power cords at all the stores. A little louder than I thought it was going to be be but had to keep in mind that it was next to the house and bigger than most of the generators I used in the past.

Assembly took less than 30-minutes and it started effortlessly right out of the box. A “field test” of the new generator was conducted two days later. After a two hour test run, with all the transfer panel breakers turned on, and nearly every component of a “normal load” placed on the generator--from the well pump to the dishwasher, and from the furnace to the refrigerator & water heater--the GP7500E generator handled the load effortlessly. However, I've recently discovered one issue that remains distressing. In the owner's manual, Generac DOES NOT recommend running the generator in rain or snow. This is equivalent to a "Catch 22" in back-up, emergency power! After all, inclement weather--blizzards, hurricanes, tornados, ice storms, etc--are the causes of power outages in the first place creating the need for back-up generators! So the food in your refrigerator must spoil because it's raining outside? Really?
