Envious Neighbors

I got tired of having to reley on my electric company to supply power if the wind blew the wrong way. So I researched and decided to buy this unit. Now all the neighborhood comes running with extension cords to plug in for power. And I have power to spare while supplying our entire house, well pump, water heater, wifes hair dryer, stove, washer and dryer and all the essential items also. Unit is easy to move around for wife who is 5'2" tall 120 lbs. Set up is easy,as for installing the wheels just shimmy unit back on supplied pallet, install axle brackets slide in axle tilt unit back,slip on wheels then rock back on wheels install front resting stand and wheels are on. Its that simple.

Well made, start on the first crank of the electric starter.

I live on the east coast of Florida so need a good home backup generator when the power goes out. Power was out for two weeks after the last big hurricane. The GP7500E is an upgrade from the 5500 Watt generator that ran almost constantly during the two weeks power was out. I wanted to ensure the same performance so Generac was my choice.

Excellent purchase

After 3 years of ownership with w1 hr/year running, had to run generator for 4 days continuously with time-outs for refueling and oil-checking. Clean gas, fresh oil 2 days prior to weather event and when needed, the generator started immediately, took the load with no surging. Minor light flickering of LED lights when dimmed, but voltage was spot-on and consistent. Heavy motor starting loads did not change generator output or tone and fuel useage to run 4 bedroom house with well, furnace, lighting, entertainment, refrigerator, dish-washer and on occasion electric oven was about 5 gallons per 24 hour day. Generator is well designed and apparently bullet proof.

Great Generator

I highly recommend this generator to everyone. My GP7500E was easy to set up and get started right away. It will be nice when the power goes out here in south Arkansas again and I can just start up my generator and not miss a beat. This generator will do all we need to do. Thanks Generac.

No power :(

Well, I bought this a couple years ago to use when we go camping. I used it once and had no issues. Today I got it out to power my furnace in the house. None of the outlets have power. I checked the breakers and no luck. I tried the GFCI, but it won’t trip because of no power.

Great value for the price for emergency power

My wife and I purchased the GP7500E this year for use in emergency power situations after a great deal of research. We moved into a hurricane prone area af ew years ago, and were without power for several days after Irene with a one year old in the house. Since we're on well water, it was a miserable few days! Never again... The GP7500E was easy to setup for the first time, except for one small thing. Strangely, the manual called for 1L of oil, and provided a single bottle, but I found that it required close to 1.5 L in order to fill the engine crankcase appropriately. In any case, I was amazed how quickly the generator started at the push of a button. It runs like a top! Now my family is better prepared for the next ice storm or hurricane thanks to Generac.

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.

The perfect Generator for my house.

This is the perfect generator for running my house when the power goes out. It's really easy to start with the remote start and is quiet compared with other generators I've used. It has a big gas tank so your not constantly filling with gas to keep the lights on. I'm very happy with this generator and with Generac

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.

Easy assembly, easy to staret.

Assembly was easy, Cut out of box and followed assembly instructions. Instructions to prepare for running were very clear. Started with some difficulty, felt hard to pull to start. Second time I started it was easy. Tested it two weeks later and had no problem starting. has all the power to run what i need during power outages. Great product.
