Fort Collins, Colo., April 21, 2015—Advanced Energy Industries, Inc. (Nasdaq:AEIS), a leader in precision power conversion solutions, today announced that it has been awarded 325 MW of solar projects by Swinerton Renewable Energy.  The installation and commissioning of the portfolio of projects is expected to begin in 2015 and continue through the middle to end of 2016.

As one of the largest solar contractors in the nation and the top solar contractor in California, Swinerton Renewable Energy specializes in installing utility-scale solar projects throughout North America.  

“After evaluating the inverter market, we determined that the Advanced Energy 1000NX inverter will allow us to maximize our solar energy production while reducing balance of system and construction costs,” said George Hershman, VP and division manager for Swinerton Renewable Energy.

The AE 1000NX inverter delivers a 98 percent weighted efficiency rated by the California Energy Commission (CEC) and 98.1 percent peak efficiency.  The inverter's self-contained, closed-loop air-to-liquid cooling system and component selection offer maximum rated power at desert temperatures, along with significant balance of system savings from the unique +/-1000VDC topology.  With a full complement of utility controls, the AE 1000NX also ensures reliable integration of renewable energy into the power system.
