Intersolar Europe 2013, GERMANY: Eltek will showcase its new THEIA HE-es system and updated THEIA HE-t solar inverter product range at Intersolar Munich (19-21 June).
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.
Eltek’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.
