Good solid product!

I have had this generator for 3 years now. Due to a more dependable electric grid lately, I haven’t needed to use it for a power failure. I do however try to start it quarterly for preventative maintenance. I keep the battery charger plugged in since the control seem to drain the battery constantly. Last week when I tried to start it, the battery was low and I couldn’t start the generator. The manual pull worked, and I ran the generator for 1 hour. I guess I’m in the market for a replacement battery.

excellent quality

[This review was collected as part of a promotion.] Living in Florida we often get hit by pretty bad hurricanes during the summer months .Having a young child in the house can be a bit tricky and stressful at times especially when there is no cold air or nothing cold to eat or drink .I love the fact that this generator is so easy to operate and move around that i can work it myself without the help of hubby .I love this beings he works and isn't always around so being able to power , hook up ,and move the generator by myself is a must . There is a fuel gauge on the top part of it so knowing when your fuel level is getting low is pretty easy .The hour meter on it i like also so i can determine how long i have ran it for .I like the overall design and features it offers . There is a fold down handle which makes it easy to move and nice for storage . It was designed to shut itself down if the oil level becomes too low to operate safe guarding the equipment from damage .Very easy to assemble right out of the box . I also like that when its running the sound coming from it isn't to loud like other brands i have used in the past . Overall a nice generator for the money

Looks solid

This is for the GP7500E. I can't do an operation review because I just finished setting the unit up and have not used it yet. It was purchased as a backup electrical source for our home. Setup was easier than reviews led me to believe, specifically putting oil in it. You do need a funnel to add oil, and I did use a funnel and hose that I already have, but a funnel with a long neck would work fine. The first unit I brought home was replaced by Tractor Supply after purchase because the spark plug boot was broken. TS was going to replace the unit with another unit in stock but the other unit also had a broken boot. They replaced it with a unit from a different store. Might be a coincidence. I opened the box and checked the boot before I brought this one home. I'm sixty years young but didn't have a problem putting it together, although it is heavy. The only piece missing was one of the little bolts that hold the battery terminals on. The unit looks good, though. I have intentions to fire that puppy up and put a load on it to make sure it puts power out. I don't know if I'll be allowed to do a second review after using it, but that's the plan.

Excellent Choice

I bought this equipment to be able to supply energy to my residence due to the passage of Hurricane Maria through Puerto Rico. Its fuel consumption was high but it did not fail me at any time. Easy to perform maintenance. I recommend it to anyone with closed eyes.

Simple/easy/user friendly

I just picked up this generator under the strong recommendation from an electrician. Fantastic advice. As mentioned above it is easy to use and laid out quite simple. I find it to be built solid and durable. I love the electric start feature as well as the pull start in the event the battery is too weak to crank the engine. Battery came charged when I received it and even though we had temps at -20 to -30 all month she still fired up quite easily. Highly recommend this generator.

Great product

Had to replace the generator I left behind in my previous home after 14 years of use. It was a Generac. I looked at several other brands, but settled on the Generac because of the reliability, wattage and value. Received it yesterday, assembled the wheels, feet and battery, and it started on the first try. Thanks.Tim31

Reliability!!!

I purchased this product after reviewing several manufacturers. I was looking for a size that could provide most of the convinces we are used to in the event of an outage. I have a Generic 4000XL that was good but not big enough. We had a six day outage due to a tornado that left most of the city without power. The 4000XL failed in the first five minutes due to a winding wire that got caught in the armature and shot the voltage regulator. This outage convinced me to double the size of the unit as it became a nuisance switching power cables. It would be great to be able to afford a standby natural gas unit but resources are tight. This unit performed very well!!! Even though it is battery start, it started easily manually and on the first pull!!!! Now I need to see if the 4000XL is repairable for smaller building projects that do not need lots of 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.

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.

Great generator for power backup

I purchased the GP7500E to replace a smaller 3250 generator to provide backup power for my house. Last December we had a power outage in the middle of a winter storm, the smaller generator worked for a few items, but I wanted to power more circuits in the house. I installed a transfer switch so I can power the furnace, refrigerator, TV, computer and several lights in the house I assembled the generator, added oil, gas and connected the battery. It fired up right away! I definitely like the battery start! I did a test run on the house and everything powered up as expected, now to wait for the next power outage.
