Power-One Enters Mega Wind Power Market

Power-One, Inc. (NASDAQ:PWER), a leading provider of renewable energy and energy-efficient power conversion and power management solutions, today announced that it has delivered its 2.5 megawatt (MW) Inverter (“Generator Control Unit”) for use in large off-shore and on-shore wind turbines to a leading US wind turbine manufacturing company. It is expected that the inverters will be deployed in an off-shore European multi-gigawatt (GW) wind farm under development.

With the delivery of the 2.5 MW Inverter as its entry into the large wind energy market, Power-One has built on its leading technology to provide the renewable energy industry with solutions for large-scale projects. The current design will support towers with a capacity of 5-6 MW, as well as for future designs with capacities over 10 MW. Further, the inverter incorporates liquid-cooling technology and medium voltage, designed to reduce customers’ footprint and cabling costs.

“We believe the global wind turbine market provides solid opportunities for growth as global economies strive to meet renewable energy standards,” said Alex Levran, Senior Vice President and Chief Technical Officer of Power-One. “This design win and successful delivery highlights our strength in renewable energy, while also providing us with an excellent opportunity for expansion into the ‘mega wind’ sector. Power-One is committed to expanding both its solar and wind power product line in order to meet our end-customers’ needs. The success of this project enabled us to develop critical technologies for our future wind and PV inverters.”

The units are currently available for production and is compatible with a wide range of wind turbines. The 2.5 MW inverter incorporates innovative IGBT-based design and delivers power to the grid from Permanent Magnet Generators (PMG). Power-One’s 2.5 MW inverter has the following unique features:

* Medium voltage 5,500 VDC (Voltage Direct Current): lowers cabling investment
* Liquid-cooling: industry leading density (10W/in3) and higher reliability
* High conversion efficiency (98.5% at full load): increased power delivery to the grid, enabling higher return on investment (ROI)
* Modular design: permits flexibility in sizing multiple inverters for wind power generators in excess of 10 MW
* Low output voltage harmonics distortion (THD<3%): provides higher power quality delivered to the utility grid

With its commitment to offering a complete line of Renewable Energy products, Power-One’s technology is applicable to large commercial and utility installations in the Photovoltaic (PV) market as well. The liquid-cooling technology, as well as other technologic enhancements that were designed for the 2.5 MW wind inverter, are being incorporated into the next generation of Power-One’s commercial solar inverters. With the launch of the 2.5 MW inverter, Power-One now provides inverters for large and small wind, as well as a complete array of PV products, ranging from residential to commercial and utility-grade.

Power-One designs and manufactures energy-efficient power conversion and power management solutions for alternative/renewable energy, routers, data storage and servers, wireless communications, optical networking, medical diagnostics, military, railway controls, semiconductor test equipment, and custom applications. Power-One, with headquarters in Camarillo, California, has global sales offices, manufacturing, and R&D operations in Asia, Europe, and the Americas.
