Excellent Purchase

Living in Florida and going thru many hurricanes this year we decided to buy a generator. did not have to use so far but just testing the unit, from the easy set up to the easy start we are now prepared for many seasons to come.

Easy for even a girl!

After pulling the cord over and over on my old unit, the electric start on the GP7500E makes use of this generator so easy! So far so good on the testing and use with the transfer switch. It just works.

Quality Product

This is the second Generac Generator I've purchased. Living in Central Canada I know that I will be faced with a power outage at some point. These generators will keep my heat, lights and sump pump running. It's worth the peace of mind.

Great Backup Genset

I'm really pleased with my Generac 6500e generator. I replaced a 14 year old unit with this one and I feel like I now have a reliable back up when the storms come and the power goes out.

This product started up with little time, and is what I expected.

The oil which came with generator was not enough to fill as the manual stated 1.6 quarts. Needed to add almost another qt. Not sure of the weight of oil that was provided with the generator, not on qt container..

emergency power

Very nice generator, runs well and not as noisy as I thought. I haven't had to use it in an emergency as of yet but I am certain it will perform to my expectations.

Powers my whole house except heat pump

Nice product. Louder than what I care for but I guess I can handle a little noise during an outage. It could be made a little more friendly for service and to maintain. I would really like to be able to power the heat pump/AC
