FOR IMMEDIATE RELEASE

Magnetek, Inc. Announces PVI-Central-50kW Units Available for Delivery

Menomonee Falls, Wis. – May 28, 2008 – Magnetek, Inc. today announced that PVI-CENTRAL-50kW units with 208 Vac, and 480 Vac output voltages are currently available for delivery. The PVI-CENTRAL-50 grid-tied system is designed for commercial solar applications such as office, apartment, or industrial buildings. Maximum Power Point Tracking (MPPT) algorithm maximizes energy produced under varying light conditions. The inverter’s Insulated Gate Bi-polar Transistors (IGBTs) reduce thermal energy losses for optimum performance. A wide operating voltage range of 330-600 Vdc increases energy collected.

  “The PVI-CENTRAL-50 is a complete turnkey solution for connection to low-voltage public utilities. Our field-proven designs reduce the time and cost of installation, assure a long service life and enable best-in-class price and performance value,” said Ross Smith, Vice President of Magnetek’s alternative energy group.

When the voltage drops below 300 Vdc the unit goes off line, providing nighttime disconnection of the transformer to eliminate undesired losses. A string combiner box is optionally available to parallel, protect and monitor all of the photovoltaic strings and to enhance the monitoring and diagnostic capabilities of the system. The unit’s standard five-year warranty is extendable to 20 years.
