AUO introduces its first residential energy storage PowerLegato


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.

PowerLegato's ergonomic design has won iF and red dot 2013 design awards. To top it all, the sleek and stylish device has been recruited by red dot to be exhibited in its design museum in Singapore from August 1, 2013 to July 31, 2014.

AUO has long been dedicated to providing innovative green solutions. The Company will continue to develop user-friendly, reliable energy management products for smart homes worldwide to assist customers in realizing energy freedom.
