![]() ![]() (1)Ět 0.25s, with a solar irradiance of 1000 W/m2 on all PV modules, steady state is reached. Run the simulation and observe the resulting signals on the various scopes. The inverter, the 2500 W residential load as well as the neighbors' load are connected to the 240V secondary winding. The transformer 240 volt secondary winding is center-tapped and the central neutral wire is grounded. The grid is modeled using a typical pole-mounted transformer and an ideal AC source of 14.4 kVrms. The controller uses a voltage regulator outer loop and a fast inner loop current regulator to generate the appropriate reference voltage (Vref) for the PWM generator controlling the full-bridge converter. “This program will help them become experts on metal roof attachment solutions.The Inverter Controller: The inverter control maintain the DC link voltage at 400 V while keeping a unity power factor. ![]() “We want to provide industry leading knowledge on our products so our customers are fully aware of the value of each solution,” Haddock said. ![]() These lessons are centered on S-5!’s products and their applications, and designed for contractors, architects, engineers, installers, EPCs, homeowners and do-it-yourselfers interested in installing solar on metal rooftops. Participants can login to S-5-University via the company’s website, where they can select a variety of courses, take brief quizzes at the end of each unit and earn certificates upon completion. “Our goal is to provide our customers and the greater solar industry with all the necessary information and tools-a one-stop-shop to understand all the ‘whys’ gaining insight to make their jobs easier,” said Jessica Haddock, S-5! marketing manager. They worked with the S-5!’s team of technical experts to create a series of step-by-step training courses to train individuals and teams from the ground up. ![]() Curriculum was developed through interactions with customers and industry professionals. S-5!’s new curriculum was created by husband-and-wife team Shawn and Jessica Haddock, both employed by the family-owned business. The first series on S-5-University is a crash course focused on solar mounting and metal roofing. ![]()
