Apr 29, 2009

April 29, 2009 — National Semiconductor Corp. (NYSE:NSM) today announced that it has passed rigorous testing and received product safety, emissions and environmental compliance certifications for its SolarMagic™ power optimizers. SolarMagic improves the output of solar arrays when affected by real-world conditions such as shade, debris and panel aging.

TUV Rheinland of North America performed the safety and emissions compliance testing and certified National’s SolarMagic power optimizers to meet requirements for UL1741 and IEC 61010 safety standards as well as FCC Part 15 (Class A&B) and EN 61000 emissions and immunity standards. The SolarMagic power optimizers comply with a standard well recognized by the photovoltaic industry, the UL1741 standard.

MET Laboratories Inc. performed the environmental compliance testing and certified SolarMagic to meet the requirements for IEC 60529 (IP68, the highest possible ingress protection) and NEMA250-2003 Type 6 enclosure. This ensures the product’s electronics are well protected against elements including dirt, water and ice.

“TUV Rheinland has been on the forefront of independent Green Energy devices testing for decades. National Semiconductor has met the strict requirements of the TUV Rheinland's test regiment, and we are delighted to assign our seal of approval to the SolarMagic power optimizer,” said Matthias Heinze, director or technology for TUV Rheinland.

"Customers are looking to National Semiconductor for a system that can ensure both safety and system reliability. Achieving this set of stringent worldwide certifications is the culmination of months of rigorous testing and inspection" said Ralf Muenster, director of National’s Renewable Energy Segment.

Using distributed electronics throughout a solar installation, SolarMagic recoups up to 57 percent of energy lost due to real-world conditions. SolarMagic power optimizers will be available to customers in North America and Europe in May 2009. For more information about SolarMagic, visit www.solarmagic.com.
