Wanting a generator for years

Being a new home owner I always thought about power going out. Well power went out! Went to local hardware store many different options I’ve heard from other people generac was top of the line a little pricey but well worth it. Will recommend to anyone I know

Save your money

What a waste of money. Worked great for the first month, now it won't stay running for more than 20 minutes at a time. Any time you put a load on it, it dies. This seems to be especially true if you have to use it on hot days. (Which when you're using it on an RV is when you need it the most).

superior product

A power loss at our daughter's home led to our purchasing this product which was of such superior quality to the "store" brand as to make this an easy decision. Quick and relatively easy set up (one balky nut/bolt) got her the power she needed to save a freezer of food. This product is sturdy, solid and easy to start.

Overall a good generator

I bought my GP8000e a few years ago. It's been a fairly good machine overall.It's fairly easy on gas. We run a light load most of the time. Fuel consumption is somewhere around .33 - .5 GPH. There's plenty of power on hand for when the submersible well pump starts. You hardly even notice it. The electric start is a great feature. The battery charger is also another good design feature. It was a wise choice to do it that way. There have been a few downsides. Cold starts around 0 deg F can be a little difficult. Keep a can of starting fluid on hand and use it sparingly. I had to remake a few of the welds on the frame. Though very careful to use non-ethanol premium fuel treated with stabilizer ... the carb did need to be removed and cleaned in it's second year of operation. It's probably best not to run the carb dry of fuel. Another thing is that the steel fuel tank began to rust and the fuel gauge clouded up within the first year. It might be helpful to redesign the start/run/stop rocker switch.You can inadvertently hit the starter with the machine running when you are intending to shut it down. In summary ... the core of the machine ... motor and alternator are pretty solid. The peripherals like the frame, fuel tank, and rocker switch could use a bit of improvement.

A great backup system

We had a standby 12K natural gas backup generator from Generac in upstate NY and when we moved to eastern North Carolina we had nothing so we decided to go with a portable. Purchased the Generac 7600E (electric start) and had a electrician wire a 10 circuit panel into our house circuits. When the power goes out, we just plug the generator into the house circuits, start it and turn on the house circuits 1 at a time. Works wonderfully. My only wish is that the electric start battery system had a meter to tell the user how much voltage was left in the battery. Overall cost about $1500.

Good value for the features

We chose the 6500E over other models due to it's many positive reviews from multiple sites and its features for the price. I especially like the number of available 20 amp outlets plus the 20 foot power cord. I specifically wanted the electric start and the automatic voltage regulation, and the rubber outlet covers are a great addition! Cons: The set-up instruction card had several minor errors and omissions. For example - the set up instructions did not mention that the fuel line was disconnected at the shut-off valve and needed to be connected by the owner. Good thing I saw it during my initial inspection. Suggestions: An onboard voltage meter (and maybe a manual voltage adjustment) would be a great addition, so the output voltage can be monitored without needing a separate meter. And it would be nice to have an onboard power meter showing amperage draw. But, for the price this model is perfectly adequate for our needs. Unfortunately, the week we received our generator, the price dropped $50. Wish I had waited one more week.

Quality Generator!

[This review was collected as part of a promotion.] This is a good powerful Generator. It will keep my furnace, refrigerator, and freezer working during a power outage. The instructions to assemble the Generator could have been better. It took a little time to assemble it. Overall a really quality Generator.

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

Great generator overall

Uncrating was simple, as was setting it up. No missing parts. Followed setup directions which were fairly easy. Added oil and gas. Turned fuel lever on and pressed the start button and it started right up and ran great! Would highly reccomend this generator. You will not be dissapointed! Let the power go out. I am prepared! Thanks generac!

GP15000 Surges

I've had this generator a while, it has always surged when a load was applied. I have a factory service manual.Generac would not let me speak to a tech to further diagnose it, they tell me I have to take it to a service shop. I am afraid the shop will throw parts at it until it is fixed, assuming they do not replace everything.
