Advanced Energy(R) Introduces the Solaron(R) 250 Photovoltaic Inverter

FORT COLLINS, Colo., — Advanced Energy® Industries, Inc. (Nasdaq: AEIS) today introduced the Solaron 250, expanding AE’s line of high-efficiency, transformerless, grid-tie photovoltaic (PV) inverters. With a power level of 250 kW, the Solaron 250 is ideal for applications such as commercial rooftop installations. Building on the success of the previously released 333 and 500 kW Solaron inverters, the new Solaron 250 provides customers with another option to achieve the lowest levelized cost of energy (LCOE) available in the industry.

“The Solaron 250 extends our Solaron inverter line to a new power level that has excellent growth potential in the commercial PV market,” said Dr. Hans Betz, president and CEO of Advanced Energy Industries, Inc. “The American-built Solaron inverters are particularly well suited for programs that have buy-American requirements, such as federal building projects and projects supported by the American Recovery and Reinvestment Act.”
