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.

Excellent

[This review was collected as part of a promotion.] We finally were able to try it. He is a beast! It can power an entire home. Everything was in the box to assemble it. Very heavy ( I think it’s more than 230 lbs). It has tires that need to be installed so it can be moved. The noise is not as loud as I was expecting. Has a lot of power. Runs on gasoline, propane and natural gas.

Great emergency power for necessities

I've been very happy with this generator. I set it up as soon as I brought it home because I wanted to ensure it didn't have any issues. It started right up and produced power. I drained the fuel and put it in the garage. I use the generator box as a cover so other than a few disrespectful spiders it looks brand new. I've only had to use it twice in the two years I've owned it and both times it fired right up, as soon as I remembered to turn the power switch on. We used it to power the refrigerator, tv, satellite receiver, and a light. As expected, it had no problem powering those. As for the sound, I don't really consider it quiet. I put it about 20 ft from the house under a shelter, ran extension cables through the window, put a towel in the window to seal out airflow and some noise. We can easily hear it in the house even over the tv at normal levels. I wouldn't consider it loud but it's much louder than the small generators I've seen used for tailgating. I'm not trying to compare the two. I'm just trying to give you a frame of reference. It wouldn't keep me from buying another one if I needed it. I don't know the limits of this generator but if you want to have power available for the basics when there's an outage, I believe this will work for most people.

Worth every cent!! Top of the line!!!

[This review was collected as part of a promotion.] This is absolutely an amazing generator—-I mean, top of the line brand, and just remarkable specs. It can run on gasoline, liquid propane, or natural gas. It offers 12500 starting watts of power and 9500 running watts. This generator gives me so much comfort that if something happens, I know we will have power and everything will okay until the power comes back!!! I highly recommend this generator— worth every single penny!!!

Tbis product is expected to meet our needs during a storm caused power outage!

The.instructions for assembly were easy to follow. The instructions were straight forward with all parts included. The generator started on the second pull and worked flawlessly. I feel confident the generator will help keep my family comfortable during an extended power outrage. Having the generator and being able to connect it to the house is very convenient.

Best generator I've ever owned!!

Having had 2 other generators over the last 20 years, this one out-performs all the others. It starts so easy, I really do not need the electric start feature. It has plenty of power to operate the house. We seem to have frequent power losses, so having a back-up is a way of life.

Generac 7500 E Generac Power washer

In December of 2013 we had really bad storm, we lost power for three days we had no power in the house everything went bad, so we went and got a Generac Genitor and we haven't had another storm or power outage since. We also have a Generac Power washer.

Good product, easy to set up and use but heavy and hard to move on any incline.

My generator arrived quickly as was easy to put together. It has worked well and more than met our needs. However, it is very heavy and hard to move. Our driveway has a slight incline to it. The weight plus the small tires, which are tubeless and hard to keep inflated or replace, makes it almost impossible for my wife to move out of the garage to use. Also, be sure you keep your battery charged. That said, I'd buy another one.

We trust Generac to provide well made, reliable equipment to protect and serve our home.

Our portable generator is the perfect size for our current home needs. We purchased it to run our home in emergencies. We have lost hundreds of dollars in freezer food in the past due to outages. We bought our portable Generac to make sure we can function in any kind of emergency; at home or, if we have to relocate temporarily for some reason, it can go with us. We also plan on getting a larger permanent Generac in the near future, to monitor our home all the time and run it when needed. We trust the Generac name and feel safe and protected knowing it is here.

Works great for emergency backup power

After several years of wanting a generator for backup power during utility power outages, and several years of putting it off, I finally bought a Generac GP8000E. I chose this model because it just happened to be available where I was shopping and because of Generac's overall good reputation. I also wanted a generator in this 7500 to 10,000 watt category. I added a third-party mechanical lock-out mechanism and a 40 amp double pole back-feed breaker to my main breaker panel, and fed it through a 30-amp power inlet box. The mechanical lock-out acts as a manual transfer switch, in compliance with electrical codes and safety regulations. This keeps me, my generator, my house, and power company personnel all safe. This arrangement allows me to power my entire house (except my central air conditioning) all on the GP8000E. My historical electrical usage data indicated that during non-A/C months, I never drew more that 5000 watts from the power company at any given time. Thus this 8000 watt -capable generator is perfect! I even measured the AC current with typical household loads all turned on (lights, refrigerator, basement freezer, computers, etc.) while running on this generator and I got a reading around 7 to 10 amps on each "hot" leg of the 240 volt 30 amp feed from the generator. Thus I still have a very comfortable "cushion" before I approach this generator's maximum power rating. I bought this generator about 2 years ago. I've only needed to use it a couple of times, but tonight I *needed* it! It started right up and ran continuously for about 7 hours straight. No problems. It provided all the power we needed for lights, refrigeration, TV, and computers all without a hiccup. I'm very pleased.
