June 4, 2013 /PRNewswire-FirstCall/ -- AU Optronics Corp.
("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO)announced today that PowerLegato, its first residential energy storage system designed specifically for the European market, will be launched at Intersolar Europe 2013 and available this coming Fall. PowerLegato is an integrated solution capable of supporting hybrid energy inputs and outputs, and ensures safe operation with its EnergyOptimizer and battery management system (BMS).
Eligible for German incentive program, PowerLegato is specifically designed to enable customers to better harness energy utilization in the current market environment, where the primary concern of using renewable energy is its stability in supply and self-consumption. The smart energy storage system includes battery modules, inverter, charger, battery management system (BMS), and energy management system. The all-in-one pack contains complete but fewer components to ensure quicker system installation.
To make it all the more compact, advanced lithium-ion batteries with high volume energy density are used to achieve ultra long battery cycles. PowerLegato also supports hybrid energy inputs and outputs. Users can switch freely between photovoltaic's DC and grid's AC sources. When PowerLegato is installed with a PV system, the main power supply will come from the PV system in the daytime, and PV sells surplus power to the grid after PowerLegato is fully charged. In the nighttime or on a cloudy day, the power stored in PowerLegato can be used first, and that from grid acts as a backup.
The specially devised hybrid inverter and charger architecture, in addition to the bundled EnergyOptimizer software and BMS, helps users to obtain maximized power independence and ensure safe operation and longer battery life. The system, with one switch only and an intuitive, password-controlled touch panel, is a perfect fit for homeowners to operate efficiently and safely.
