Best helper at the worst time!

I am not a big fan of generators running in the nights disturbing our good neighbors. But, due to the increased power shutdowns, it became an essential part of our daily life. All the features of this generator are excellent, other than its sound level in our quiet neighborhood.

Was able to get an outstanding deal on a slightly used, 0.4 hrs., 15000e.

I wired the generator up to the house and tested it out. Ran everything including a 3.5 ton AC. Now ready for the inevitable South Florida Hurricanes. Unit started right up after I replaced a 4 year old battery that was completely dead. One of my best purchases.

Awsome power and reliability!

Great portable unit! I bought it after hurricane Irene to run a Franklin Electric 3 HP well pump. I was without power for 6 days during the freak October snow storm here in the north east. It ran my well, heat (circulated hot water) and two fridges; I was also able to cook and do laundry (not all at once)! Survived the 6 day outage with little worry or pain. My only warning is that this unit is heavy (to be expected) and uses a LOT of gasoline so lots of trips to the gas station. I'm currently looking into a Guardian Series 20KW natural gas model with a permenant hookup. They make a great product!

Awesome product

[This review was collected as part of a promotion.] I’ve been wanting one of these for awhile now! Living in Ohio and having your electric go out during the winter is horrible! Now if it goes out I am able to keep my kiddos warm! I highly recommend this! I used it on my friends RV over the weekend and it works amazing! Love it.

Outstanding Generator

I'm a generator mechanic by trade (military) and I know quality when I see it. I am very impressed with the attention to detail. From the oil drain line to the control panel battery charger to the extra large fuel tank. Every aspect of this generator is excellent, to include all the parts needed to perform the first scheduled oil change and maintenance. In that kit was also a funnel, towel, spark plugs, oil, oil filter, air filter, foam pre-filter, etc. The frame is extra heavy duty and looks as though it would take the worst of abuse. Some other noted features: spin-on oil filter, idle control switch, fuse protected control panel, a wide variety of fuse protected power outlets, extra large muffler, electric start, never-flat tires, and an incorporated lifting eye. The instructions were easy to read and initial setup took only 20 mins or so. After hooking up the battery (came 100% charged) and filling with oil, one short push of the start switch and it was up and running. Smooth idle and steady clean power top it all off. This is an outstanding generator and I can tell that people (engineers, designers, etc) put a lot of thought into its design. I definitely recommend this generator to anyone looking for reliable backup power and/or portable power.

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.

7500E generator

I purchased this product due to several power outages in the last months. Easy set up, with the electric start makes this product above the rest. I recommend this product to anyone and everyone. I also use this when I'm building a new barn or sheds. When ever you need power away from a power source, this product will take care of all your power needs !!! Excellent Product !!

This unit meets all of my expectations so far

I purchased this unit to replace an older smaller unit. It runs quiet for its size, and the large fuel tank means I don't have to fill up in the middle of the night. It is installed in such a way that I can feed the entire 200AMP Panel, and choose which circuits I want to power. I used it during our last snow storm, and put 14 Hrs on it of continuous use other than to shut down to fill it once. I am able to run my furnace, Well pump, Sewer pump, upright freezer, 20Cu ft refrigerator, 1.5 Cu Ft refrigerator, one light in each of the 3 bedrooms, a light in the living room, and a cable box & flat screen TV, and night lights in the bathrooms. If you have children, you understand the need for the TV and night lights! I usually leave about 10 circuits powered on, and monitor what is used on each circuit. Do you homework, figure out your wattage draw, and you will have no problems. Just be sure to balance your load draw. I chose the Generac because of their products are built well, and have a great track record. Best investment by far to keep a "happy family" when the power goes out.

Proud owner

Easy to assemble well explained instructions. You can see and feel you have a solid well built piece of equipment. Started without issue however was louder than anticipated or had hoped for. Peace of mind knowing that my family will be comfortable through power outages thanks to Generac
