[This review was collected as part of a promotion.] Last year when a hurricane hit we were without power for 3 days. I said then that I would not want to go through that experience again without a generator. I was worried that we would lose all of our food in our refrigerators as well as our freezers and that would be devastating for us. For years I have heard that people had problems with carbon monoxide issues with generators so I was so happy that this one is equipped with CO Sense. I feel safer using this with my family. This generator has an electric start so it is even easy for me to start. I am thankful that I do not have to worry anymore about what we would do without power. In the long run this will save us a lot of patience and money since we will be able to run our refrigerators and freezers.

Just unpacked my new GP7500E. Easy setup to get running. Powered a few items just to test the generator. Will be easy enough for my wife to use before I can get home. Only disappointment was that there wasn't the extra cord included (twist lock to 3 plugs) but not a deal breaker.

I have not started the generator yet but in getting it ready I've identified a few disappointing aspects. First and probably the biggest disappointment is the requirement to measure valve clearance at every 50 hour interval. The owners manual informs you this is pretty complicated (without describing the procedure) and suggests you have a qualified dealer do it (...did I mention the requirement for every 50 hours of operation?). The generator came with a note indicating the unit is "shipped without oil" and they supply 2 quarts for the required 1.7 quart capacity. When I poured the first quart in, the oil level was well above full on the dipstick ….indicating the engine was not even close to empty of oil. I also found the assembly instructions to be near non-existent because the exploded view of the assembly was so small in the users manual; also - it did not reference torques for any bolts or wear lock washers vs. nylon nuts should be used. I also noted two wires stretched very tight across the oil filter - which needed to be disconnected and re-connected following a less stressful path. I truly hope the generator will work well despite these initial findings.

I bought 3 years ago and used it this past 3 days straight with no issues. I ran 3 refrigerators, all the lights in the house, garage door openers, electric heater, coffee pot, and toaster over. Really impressed with the power output. Plus the tank is fairly big, and last a long time once topped off. Only con is that it is really loud.

Helene came through, purchased this generator and it ran for less that 25 hours and wouldn't keep running. Took it to the local services center and had to pay $40 for them to evaluate it for repair. Makes me leery of investing in a whole home system through generac.

2 of my friends, my sister and I brought the GP6500 Generator 2 days after Hurricane Helene hit our hometown in Georgia September 2024. I assisted 1 of my friend with the assembly process and I assembled both mine and my sister's generator by myself. It was a simple process. Once gas was added to the fuel tank, all of them cranked up on the first pull and stayed running until they either ran out of gas or was turned off manually. The generators was a life saver. They supplied power to what we needed and never failed to perform perfectly. They were used for 6 days before the utility company was able to provide us electricity again. I am now in the process of trying to get a manual transfer switch and power inlet box installed so that I can be more prepared for the next power outage. Thanks Generac.

I purchased this generator as a back up for my home, and used it only 5 hrs and I haven't found it to be any better or worse to setup or features it offers. It is not as quiet as I had hoped. I have owned or own 6 generators. Size of those units have ranged from 2000w-15,000watts. The gas cap was very difficult to remove to fill with gas. Attaching the battery cables was not easy at all and I have some mechanical ability. Battery location could be better. Oil that comes with the unit does not give a 30W, 10W-30 label and does not indicate the size of the container, 32oz, 24oz, 42oz.. I did enjoy the ease of transporting it from the house where I assembled it to the shed in several inches of snow, where it is stored. That distance is 125 ft. The Generac brand has been around for years so I hope to get 1000 hrs + of use with no mechanical service issues.

Great looking product, great features, and easy to set up and start first time.. Quiet little generator, as well.. ( And the color, is splendid..matches our Kubota Tractor ! ...Cannot wait for first storm to try it out !~ Great job, Generac ! ! !

Bought the 17.5 KW to run my whole house, including the well. My wife is dependent upon ventilators to help her breathe and I needed a generator big enough to run the well and AC units since we have several power outages a year due to hurricanes and storms.

With the ever increasing unpredictability of the weather, I found it necessary to have a generator on hand to ensure comfort and the ability to cook and keep perishable products from spoil. To relax in the relative comfort and glow of my home while I look down the street and see darkness reinforces my belief that purchasing this generac generator was a great idea.
