Generac 7043
I have only had my Generac 7043 22kW generator for 2 weeks and I am already happy that I made the investment. No sooner did my electrician install my generator than 3 days later we had a power outage. Performed perfectly. Guess where all the neighbors ended up. Fast shipping and great customer service from AP Electric to boot. Very pleased. I would recommend.

Generac 22kW Home standby Generator
I am happy with my purchase of Generac's Generac 7043 22kW Guardian Generator with 200A SE Transfer Switch. I am not sure why anyone would purchase the 20kW when the 22kW when the price is so similar. Runs great but has not been tested in a complete power outage situation has it has only been installed for about 2 weeks and we not experienced a power outage since it was installed. Great customer support and shipped the day I ordered it. Thank you.

Great Generator
I am an electrician and long time customer of both Generac and AP Electric. Purchased this Generac 7043 22kW generator 2 weeks ago and installed for a customer last week. This is the model that will replace the 6551. Not a big difference between the 2 models. The Generac 6551 was a work horse and I expect this new Generac 7043 to be one as well.
