What Others are Saying about Generac's Power Design Pro

“The engineer gave us the loads and the horsepower of the motors. We plugged the information into Power Design Pro and it gave us the proper size generator to meet the customer’s needs. With the heavy inrush currents, it was determined the alternator would need to be upsized to meet the facility needs.” – Chuck Rozycki, Senior Sales Engineer
“With the help of YC Power Systems and Generac’s Power Design Pro, the sizing of the new generator was not a problem. After inputting the three 125HP motor loads, along with the site accessory loads, into the sizing program recommended the specific Generac product.”
