Metzingen, Germany, June 10, 2015—Advanced Energy Industries, Inc. (Nasdaq:AEIS), a leader in precision power conversion solutions, announced the conclusion of a framework contract with Turkish investor A Enerji for solar projects totaling 50 MW that include AE 3TL string inverters. The string inverters will be installed in three different A Enerji PV projects and will extend Advanced Energy’s leading position in the Turkish market.

"We chose the AE 3TL string inverters based on their proven technology and outstanding quality,” said Özel Sögüt, A Enerji’s chief operating officer. “We are certain that this choice will pay off over the life of the PV system."

Norbert Apfel, Advanced Energy’s senior vice president of inverter products, said, "With the decentralized concept of the AE 3TL string inverters, large PV systems can be planned quickly and installed efficiently. The operator also benefits from a virtually maintenance-free inverter with pure convection cooling and a service concept that is simple and assures yield reliability."

The three-phase AE 3TL string inverters provide a high return on investment with a degree of efficiency over 98% at partial load. Available at 400 VAC and 460 VAC, the inverters are ideal for use in medium-voltage applications. The product line also includes UL and JP models for use in North America and Japan, in output classes ranging from 8.25 kW to 48 kW.
