Excellent Quality

Just purchased this GP7500E. Very easy set up. Started right up within a second. Love the electric start. Got a great price for a generator of this size and quality. Everything required was in the box (except the gas). The 9375 starting watts will come in handy on the day that I need it to run my household wellpump, freezers,fridges and still have power to run some lights and cooking appliances. As an electrician I have hooked up large commercial Generac generators in the past and was always very impressed with the Quality, and this smaller unit seams to live up to my expectations

Looks solid

This is for the GP7500E. I can't do an operation review because I just finished setting the unit up and have not used it yet. It was purchased as a backup electrical source for our home. Setup was easier than reviews led me to believe, specifically putting oil in it. You do need a funnel to add oil, and I did use a funnel and hose that I already have, but a funnel with a long neck would work fine. The first unit I brought home was replaced by Tractor Supply after purchase because the spark plug boot was broken. TS was going to replace the unit with another unit in stock but the other unit also had a broken boot. They replaced it with a unit from a different store. Might be a coincidence. I opened the box and checked the boot before I brought this one home. I'm sixty years young but didn't have a problem putting it together, although it is heavy. The only piece missing was one of the little bolts that hold the battery terminals on. The unit looks good, though. I have intentions to fire that puppy up and put a load on it to make sure it puts power out. I don't know if I'll be allowed to do a second review after using it, but that's the plan.

Good So Far

We purchased this generator to serve both as a power back-up to our house; and for ad-hoc use on the farm in locations where we don't have power. We have gas furnace and water heater so this size (7,500 watts) is big enough to run our well pump, sump pump, furnace, water heater, microwave, and two rooms worth of outlets. We are using a transfer switch so all we need to do is wheel out the generator and plug it in. The assembly is pretty basic (wheels and handle) went fairly well (its heavy). The oil filler cap could be in an easier area to get to (you will need a funnel to get oil into it). Once it was gassed and oiled up it started after just a little bit of choking, and after that it starts the first time every time with the push of the electric start. So far we haven't really taxed the generator yet but it has run well so far. I saw the comments in other reviews about gas leaking but I simply switch the fuel supply to off (with the easy to get to lever) and let the engine run a bit until it starts to sputter and then turn it off and there are no fuel leaks (better for longer term storage this way also). Thus, so far so good and seems it will work well for us - hopefully we never have to find out!!

Should do the job easily

I bought it for emergency power for when our tree lined street takes out the power lines. I've only run it for a few minutes so far, to test the breaker box connection. It ran the well pump, furnace, and a few lights without issue. There will be enough power in reserve to keep us comfortable if we have another snow disaster this winter.

Performance is good

I have the 7000E and from what I can see other than the covered outlets and uni handle bar, it is the same model? The only issue I have so far with the generator is that the on/off fuel valve tab broke on me when I was turning it on. Now I use a tiny vice grip to turn the valve. Hard to find what part number I need for the generator b/c I can't find a parts list but all and all a solid generator.

Good product for the money

The generator is well worth the money for a stand by system or contractors. It starts easy with the dial and battery. Plenty of power to run the essentials. A little noisy compared to others and the fuel consumption is a bit high, well worth the trade off for this price point

Crank- no Start ongoing issue

Bought this generator in May, 2018. Worked fine for a few short power outages. Live in rural area and need Generator for power outages as we are on a well and have no water when power out. In Sept 2021, we had a major hurricane come through and had no power for four days. As soon as power went out, we started Generac and it ran great for about 48 hours. At 3 in the morning, it stopped. I checked, fuel good, oil good and had been overall for only 76 hours per meter. Could crank it it but would not keep running. Took it to tech who could not fix it. Paid the $250 and sent to next tech. He could not fix it, paid over $500 for all the parts replaced Next, sent it to "Certified Generac" Tech. After months, was finally told it could not be fixed. According to Tech, Generac refused to assist him any further. After only 76 hours of run time, I now have a 450 lbs anchor as it is useless. Would love to have it working but can't afford to spend anymore when Generac will not help with a known issue for these models. (See YOuTube for verification) DO NOT BUY #Generac Cranknostart

Not bad for a mid size.

Bought a GP3600 model today. We lost our electricity in a storm 4 days ago. Easy to assemble, started right up and is powering our fridge & some lights. Nice smaller unit. Very portable & not very loud. 4-20 amp duplex plugs & 1-30 amp locking plug. Not a bad value if it holds up.

Ready for a power outage!

We have had several power outages in our area due to different readons, mainly vehicles hitting power poles and a few bad thunderstorms. No wanting to wait hours to get power restored, we decided to get a generator. We chose the GP8000E and we are very happy with it. We were able to hook up our entire home to it using a transfer switch. We shut our main power to the house and turned the generator on and it worked like a charm! All of our lights came on, our refrigerator and furnace did great, and we even tried our A.C. unit. We are happy with it. Next time there is a power outage in our area, we will be ready for it! Thanks!

This is the one!

I bought this unit because I am building a house in the country. Com Ed won't have power there for another month. It took all of 10 minutes to put this together. total 15 minutes from box to running. Loaded it on the 1st start, Wow, this will run everything I need it to. Then after the house is built, it will serve as a back up in power outages. Illinois doesn't have the best of winters out here in the country. I recomend this to any one serious about a quality generator!
