Leading solar inverter manufacturer to share advanced 3TL inverter capabilities and intelligent monitoring in hall 9, booth G01

FORT COLLINS, Colo., April 8, 2015 Advanced Energy Industries, Inc. (Nasdaq AEIS), a leader in precision power conversion solutions, will be showcasing its 3TL string inverter series and intelligent monitoring at the 7th International Solar Energy and Technologies Exhibition “Solarex Istanbul”, located at the Istanbul Fair Center from April 9 to 11, 2015.

Advanced Energy will highlight the latest version of its proven string inverter series - the AE 3TL 40/46, designed for maximum efficiency and well-suited for commercial rooftop and carport installations, as well as large-scale solar parks. The AE 3TL 40/46 inverters offer a DC:AC ratio of up to 1.75 : 1 to deliver energy production gains and increased profitability.

“Because of Advanced Energy‘s unique DC:AC ratio, our customers can deliver more energy earlier in the morning and longer into the evening in relation to the installed AC power,” explains Norbert Apfel, Senior Vice President, Inverter Products at Advanced Energy.

Even at low irradiation, the AE 3TL 40/46 inverters are over 98% efficient, allowing generated heat to be dissipated using convection cooling. As a result, they are ideal for decentralized outdoor concepts. The AE 3TL 40/46 inverters include an integrated data-logger that can send important operating data to the AE SiteLink internet portal for visualization and evaluation purposes. Performance data can be transferred via the standard cable or an optional wireless connection using the AE WirelessConnect radio module.

These and other innovations will be presented from April 9 to 11 at the Advanced Energy booth in hall 9, booth G01, Solarex Istanbul. For more information on the Advanced Energy AE 3TL product line, please visit http://solarenergy.advanced-energy.com/en/STRING.html
