This generator has about average features

I purchased this generator as a back up for my home, and used it only 5 hrs and I haven't found it to be any better or worse to setup or features it offers. It is not as quiet as I had hoped. I have owned or own 6 generators. Size of those units have ranged from 2000w-15,000watts. The gas cap was very difficult to remove to fill with gas. Attaching the battery cables was not easy at all and I have some mechanical ability. Battery location could be better. Oil that comes with the unit does not give a 30W, 10W-30 label and does not indicate the size of the container, 32oz, 24oz, 42oz.. I did enjoy the ease of transporting it from the house where I assembled it to the shed in several inches of snow, where it is stored. That distance is 125 ft. The Generac brand has been around for years so I hope to get 1000 hrs + of use with no mechanical service issues.

Both tires don't hold air. Oil bottle opened during shipping and was over everything. Had to buy locking nuts to mount handle. Looks like a "tickle

When I opened the parts package there was oil over everything. Pumped up a flat tire and now both are flat. Had to purchase locking nuts to install the handle. It appears to work well, but your detail and instruction booklet leaves much to be desired. This replaces a 15-year-old 15KW unit, so am confident that it will perform well. Along with a spare air filter there was what appeared to be a "tickler" cable/plug, but no place on the generator to plug it in (when & if needed to restore the magnetic generator load).

I believe it is the best value for the money.

This unit is very easy to set up and use. Ran the electrical system to my breaker box and it does an excellent job. the exhaust is a little noisier than I would like but well worth the money. Very neat machine and no rattles. I would like to see the battery cables re- configured to make the battery easier to hook up because I keep the battery in our home where it is warmer. Maybe clamps instead of the small bolts and nuts for the positive and negative terminals on the battery.

Worth Every Penny

I've owned my 7500E for just over 8 months now. As others have mentioned, from ordering to delivery was flawless, set up took very little time. Once I had the transfer switch installed, I ran through a test of all 10 circuits with the electrician and it barely created a load on it...even he was amazed. I'm extremely pleased with my purchase and feel very confident recommending it to anyone considering this model.

Very good quality and simple to use

Bought during a power outage and brought power back to my house very quickly. Assembly is simple and straightforward. Generator has started first pull and still starts very well with the included electric start. pushes a lot of power so nominal rating is not overrated. a bit noisy but I was amazed to see how little gas it used. Not the cheapest, but quality is top.

A Little more comfortable in the wake of the storm.

We have been thinking of a whole house backup but waited a little long, Irma hit. I ended up picking up a generator as I traveled back to FL as all the ones in town were gone. I was looking for a large enough one to run our well and refrigerators as long as needed to get power back. I arrived back to the house the day after the storm there was no power. So I opened the box and added the oil provided in the box, added gas and connected the battery, also provided in the box, turned on the fuel and slid the chock lever and hit the start button. the generator fired right up and we had power again. It was a good experience and easy to set up. We have had no problem so far.

Great product for price

I needed a generator that could power the 240v well pump as well as a few outlets and refrigerator during any power output. This Generac model came up at a great price, I could not pass it up. Unit looks basic, but has all the features and power I needed. Assembling the unit is simply other than the cotter pins for the wheels. Simpler bow tie cotter pins would have made things easier due to the restricted space due to the battery. An internal charging system that would charge the battery while operating would have also been nice. Unit is quite for the power rating. Unit is heavy, so bring a helper when you buy.

Mighty Powerful Standby

First of all Generac is the best. I have purchased many industrial generators for hospital backup. I know that Generac is quality. This unit meets all my needs for home backup without having to go to s standby unit. It was easy to assemble and started right off the bat. Much quieter than expected for its size. This unit is well built and I am sure will last me a lifetime. Fuel tank capacity and placement are optimal and I really like the built in strainer. I am very please with this purchase.

A very reliable product

Purchased on the day hurricane Sandy arrived. I ran it for 12 straight days without a problem. I only turned it off to change the oil 3 times. Very well made and dependable. A bit noisy but most gas generators are. Only knock is that the gas gauge stopped working after 2 days.

Great value for the price

Purchased the GP7500E (special sale price) at Canadian Tire. Assembled and started right up on first try. Appears to be a good quality unit, great value for the price. Just wish it came with a float charger instead of the supplied batter charger so it could be left plugged in at all times.
