I only have two hours on mine, however my bro-n-law bought one same day. He put 52 hours on his and it quit running. We brought it back and they told us we were the 38th returned generac that day. They said the co sensor will not reset so that's why they stop running. It was outside in the yard, not inside....so yeah. Safety features aren't safe when you have an elderly mother about to die from Louisiana heat and you depend on a generator and a window unit. Now question is how long will mine last, I have power back and won't know until or next hurricane. Mom-n-law surving off my coleman with Subaru motor that I bought during Katrina in 05. Almost 20 years old and still running like a champ. This generac couldn't make it 52 hours.

We frequently are affected by power outages so an emergency power source is a necessity. We chose the 7500E because of the electric start and the 7500 watts ,in less than 5 minites we are powered up and comfortable. I highly recommend a transfer switch,it makes the transition to standby power effortless. The 7500E provides more than enough power for our home.

I have yet to put many hours on this generator so my overall rating could possibly go to five stars in the future. My electrician highly recommended Generac brand of generators. My brother also owns a Generac in a very similar model. He has been happy with his model and tells me the model I purchased will power everything I need at home during a power outage. I feel confident that I now can keep my home safe and warm when the next power outage occurs.

I bought THIS generator because of the past experience with the brand, AND because this unit had a larger engine than most of the similarly sized generators. The typical 15kw genset has an 18 to 22 horsepower engine. This model has a 30hp engine!! That extra horsepower means greater power margin for starting loads like HVAC compressors. I calculated that I needed 10kw, and this units 22kw starting capacity exceeded that substantially... But in my experience I need more than the minimum because if the hvac computer crashes because of voltage drop, then starting will fail. You mush have excess power during the starting of the compressor to keep the computers happy. So I picked carefully, and while this one has much more power than I require, the price point and performance thresholds were met by *only* this generator. So I did my first test running the whole house, and this generator handled the load with few problems, but the power was very noisy, very high harmonic distortion. Some things in the house ran fine, but things powered on transformers did not like the power. The home thermostat was inoperable, the computer in the dishwasher crashed, several of the UPS systems did not like the power and complained, and my smart LED lights were very unhappy. Sensitive loads did not like this generator at all... But once I got the thermostat bypassed, the HVAC compressor seemed to run fairly well, though the compressor was noisier than normal. So to meet my needs I decided to buy the largest inverter generator that I could fine to run the house and electronics, and the Generac GP15000E is dedicated to the HVAC compressor *only*. The HVAC blower and electronics run on the inverter generator where they are fed a true sine wave. I didn't set out to buy this much excess capacity, but I still paid less than I would have if I had bought a similarly sized whole home generator, and I have a reconfigurable power plant now so I can handle any need.

Got my generator yesterday, a day sooner than I expected.The delivery man was very nice and pleasant to talk to. Opened up the generator and was pleased with the look. It took a day to find time to get it running, but when we did it ran just fine. we have a Generac 5000 that doesn't have the electric start and my husband can no longer start it, that is the reason for the new one.. Thought we could hook it up to the old switch, but it is only good for 6000 watts, so must get that problem resolved. other than that, very pleased!

This unit is a very high quality product. You will be impressed right out of the box before you finish the simple assembly. Lots of features. Reminds you when maintenance needs performed. I especially like the four outlet cord that comes with it. This cord allows you to use both legs of the 240 volts instead of just one side. This gives you the ability to use the full rared output of the generator not just 1/2. The receptacles on the control panel also allow for this same usage. the automatic throttle control saves fuel as I usually do not need 8000 watts of power when dry camping with my RV. I just retired from 47 years in factory skilled trades maintenance and I am a skilled trades instructor at a local 2 year college and I am very impressed with this generator.

I purchased the GP1800 to power a natural gas forced hot air unit. After losing power during hurricane Sandy, I used it for most of the first day and night to keep my wife and child warm. I returned home from work to find that the recoil starter assembly had failed, causing the recoil assembly to spin with the crankshaft of the engine, effectively destroying itself. I was able to remove the assembly and start the unit with a length of para-cord. On day 7 of our outage, only using the unit for approx. 6 hours per day to alternately power the heat and 2 refrigerators (individually), the unit just stopped working. The engine had seized, crankshaft unable to move at all. Oil level was okay and was checked every morning before start-up. Hopefully warranty service will be able to repair or replace unit!

[This review was collected as part of a promotion.] I am extremely pleased with this Generac generator. My husband and I had no problems whatsoever setting this up. It's actually not as loud as I suspected it would be, maybe about the same noise as a lawnmower. We were able to hook quite a bit with this (refrigerator, few lights, microwave,etc.) This will definitely come in handy this winter as we're in Western New York and get some pretty harsh weather and are constantly having the power out for long periods of time. Definitely a good investment and this generator is high quality and highly recommended!

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

Bought the gp7500e for a home backup. This machine is more than I could have ever asked for. So far, I have found nothing that I could talk bad about. I believe in great value in whatever I purchase, and this machine is just that.. Thanks Generac for a great product..
