Eltek Showcases New Solar Energy Storage System at Intersolar Munich 2013
Eltek, ASA announced it will showcase its new THEIAâ„¢ HE-es system and updated THEIA HE-t solar inverter product range at Intersolar Munich (19-21 June). According to Eltek: with the increasing acceptance of photovoltaic (PV) installations around the world and the trend of ever increasing energy costs, the next step for PV generation is increased self-consumption by the power producer.
Eltekâ€™s THEIA HE-es combines the THEIA HE-t high-efficiency solar inverter, an IP21-level enclosure, and batteries to store between 2.4 kilowatt hours (kWh) and 18.2 kWh of solar energy. The storage system enables PV system owners to make greater use of the energy they produce at a time when they need it.
The THEIA HE-es features include dynamic battery management that can use batteries only when most profitable. The system also facilitates adjustable charge and discharge limits, and is configurable for all battery technologies, including Lithium, NiCad, lead acid or sodium batteries. Using a proprietary architecture, and when connected into the THEIA HE-t, the THEIA HE-es has total DC-AC power conversion efficiency above 90 percent, providing users with the optimal PV energy storage system.
Building on the success of the THEIA HE-t inverter, new models will be available that will include integrated remote power level adjustment (PLA), system protection interface (SPI) inputs and configuration, S0 smart meter bus integration, PV shading loss reduction and energy management outputs for consumer goods control.
Lightweight and compact, THEIA HE-t inverters offer a maximum efficiency of 97.3 percent, flexible connection sets, backlit color display and integrated web-server for quick configuration and easy operation. The Eltek THEIA HE-es and updated HE-t product lines are available from August 2013 from Eltekâ€™s worldwide sales force.
