I love the stability of the Generac's power supply and the convience of the electric start.

During the ice storm of 2013 our areas' power was out for 8 days. I borrowed my brothers Generac4500 and was impressed with it's ability to supply power for services of our rural property. When you are in the country and you loose power it includes you water supply and with horses it was essential that we had a constant and dependable power supply for this period. We have since purchased a Generac7500 with electric start and it is able to supply stable power for our whole house. We have used it recently when the power was out for a day and we never missed a beat.

It is Loud but Works Well

Like others, I do find this generator to be a little on the loud side. I also have an older Generac 4000XL that is nowhere near as loud. With that said, I am very happy with the generator so far. I have run it only about 20 minutes but fully intend to give it a break-in workout this weekend. First impressions are it is substantially more than the 4000XL in ways far beyond just the wattage ratings. I like the electric start, the tank filler screen, the fuel line filter, the metal fuel shutoff valve, and many other details that just make me feel this generator is considerably more solid. I do wish it was a pressurized oil system and filter on the engine, but I could not justify the price increase to get that feature. All in all, I find this generator to be an excellent value. Yes there are trade-offs, but it will serve my home backup purposes well.

wasn't allowed natural gas or propane

I needed to run my entire home inn case of a Hurricane. This was the only generator gas powered to accommodate our needs. 50 amp service was more than enough, ran my entire home for almost 3 days till power was restored. I was extremely happy. I referred this model GP17500E to a friend he bought one and like me very happy thank god we didn't need it so far in 2018.

It would have been nice if it worked when I needed it most

I purchased the Generac 7500E model generator approx 18 months ago from Costco. The deal that I got on it made it a no-brainer to buy there. After getting it home and out of the box, set up was a breeze. I simply put in the oil that came with it (we'll get back to this) and fueled it up, it ran like a champ. Every 4-6 weeks I start it up and let it run. I don't keep much if any gas in it while it is stored as I make it a habit to run it out of gas. This past week Mid-Michigan got pummeled by an ice storm that left us without power from Sunday 12/22/2013 at 3:03 AM until Wednesday 12/25/2013 at approx 3:30 PM. No problem right, I have a generator. I got up threw the breaker box to off, went through my start up procedure in the freezing cold of the night and had my house running with power again in approx 20 minutes time. After everything was back in order, I went back to bed and laid there listening to the generator. After it had been running for about an hour I heard it turn off. I went to check on it only to find that it would not start. I was full of gas and had been running just fine. The electric start had the engine wanting to fire, but it would not turn over. I got it into an authorized dealer the next day, Monday. It was not ready for pick up until Friday 12/27/2013. The diagnosis, it was overfilled with oil. Now, as I said, I set this up with the oil that was provided by Generac. As I remember it, a premeasured amount. I have never added to the oil. My only guess is that when my unit was tested at the factory, the oil was never completely drained. The time I needed it most and it had run the longest, less than one hour, IT FAILED.

Nice and Quite

Had to replace my old generator (That was not a generac) that had for the last 15 years. Bought this from a local vendor. The unit started right up. I already have a generac home standby but It really uses the propane to run all night. I use this to just run fridge and furnace at night. The home standby was the best purchase ever. Soon as the power goes out the standby will start right up. I have the 6500 run just a few circuits when don't want the standby running. The 6500 has electric start which is nice. I was without power when 1st bought and it ran for 16 hours straight. No problems. I would recommend the generac name to anyone. After bought my home standby my inlaws bought one and love it. Highly recommend the portable 6500E.

I was very pleased with this product

The unpacking and assembly were well described and easy to complete with minimal mechanical skills. The engine started right up and power was immediately produced. I let the unit run for a few minutes and then checked the oil level and examined the unit for any leaks or other obvious issues but none were found. I would recommend this product to anyone in need of a large portable generator for emergency or other short term uses.

No Doubts, money well invested

I am very satisfied with my purchase of my GP6500E generator. It was money well invested. The quality and performance of this Generac generator is great. The installation and startup directions were very easy to follow for someone like me that is not to keen on the mechanics of putting something together. The motor is not too noisy at all, we can barely hear that our generator is on at all when working. I will definitely recommend this product to all my family. I am getting ready to purchase a Generac Home Standby Generator in the next few months.

Runs when you need it!!

Bought this to replace an older one I gave to my son, ran like a champ for years. The new one was purchased because of the Deracho that went through our area Benton Co. Iowa, August 10, 2020. Finally found one 75 miles away in Cedar Falls. First oil change 41hrs, second change at 109 hrs. The unit ran continuous for 187 hrs. straight! One pull start every time. The unit ran our 28,00 sq. ft. home, AC, frig, freezer, lights etc. Excellent piece of equipment and reliable! Never been happier. Thanks, Lee

Works every time

This Generator starts every time and I have had no problems in 2 years. Shortly after I got this unit I had shoulder surgery. The design of the unit allowed me to set a couple short pieces of 2x4 on top to straddle the fuel line and set the 5 Gallon gas can right on top over the fill hole using only one arm. The only problem I had with this unit was when I let the oil level get too low and the unit would not start without enough oil....good safety catch! I put oil in it and off it went without a hitch. I ran a refrigerator, small freezer, sump pump, well pump, furnace, TV, garage door opener, and some lights with no problems. I have used it several times now when we loose power here in the country and it has never failed me.

This is the BEST product I was able to find in this price range!

I am so happy with my purchase! I never thought I would get a Generac brand generator large enough to run my whole house for so little cash. What a value and it is loaded with features and setting it up took less than 20 minutes. And a bonus was how easy it is to move and transport so if I wish to do some camping in a state or national forest I can have power to go for my fifth wheel. Love IT!!!!!
