Power-One, Inc. (Nasdaq: PWER), a leading provider of renewable energy and energy-efficient power conversion and power management solutions, has announced that it is introducing four new Outdoor PVI-Central Commercial Photovoltaic Inverters (150kW to 300kW) for installation in North America.

Camarillo, CA - December 9th, 2009 - Power-One, Inc. (Nasdaq: PWER), a leading provider of renewable energy and energy-efficient power conversion and power management solutions, has announced that it is introducing four new Outdoor PVI-Central Commercial Photovoltaic Inverters for installation in North America. These modular inverter models, in rugged NEMA3 rated enclosures, are the PVI-CENTRAL-150-US-480, PVI-CENTRAL-200-US-480, PVI-CENTRAL-250-US-480, and PVI-CENTRAL-300-US-480 providing outputs of 150kW, 200kW, 250kW, and 300kW, respectively.


These inverters are the most recent additions to the PVI-CENTRAL Series of inverters which share a unique combination of high efficiency, ηCEC 96%, and high reliability. Attributes like these and others have made the PVI-CENTRAL a highly regarded commercial and utility inverter with a capacity of over 330 Megawatts already installed in Europe and Asia.

The new PVI-CENTRAL models feature a Master-Slave configuration that allows the unique possibility of internal redundancy with no functional impairment in case of failure. These products offer flexibility such as when the PV array is not grounded the PVI-CENTRAL can be configured in a Multi-Master Mode with multiple MPPT controllers for improved array control, reduction of panel mismatching, and reduction of energy production losses in the event of partial shading.

Additional benefits of the new PVI-CENTRAL models include: low acoustic noise based on high switching frequency, full power rating up to 40 C, ease of maintenance, and cost-effective spare part management due to the communality of parts used throughout the entire series.

Although details have not been finalized, related exhibit and demonstrations of these new PVI-CENTRAL models are tentatively planned to be held at Power-One's Camarillo, CA and Andover, MA facilities in the March, 2010 timeframe.
