AU Optronics (AUO) is to launch its residential and commercial energy storage system, Powerlegato, into the European, Japanese and Australian markets on the back of receiving the necessary certification.

The Taiwanese company launched the residential version of Powerlegato into Europe in 2013, when it qualified for the German home storage subsidy. According to the company’s latest announcement, the system is now also eligible for subsidies given out for the purchase of residential lithium-ion battery-based storage systems in Japan.

Certified by testing house TÜV Rheinland, the system allows users to switch between AC grid energy and DC energy, as generated by a photovoltaic system. It can run on or off-grid, in Germany or the UK. The company also claims that software integrated into the system allows for easy switching between these hybrid power sources; between grid power and PV-generated power, as well as serving as emergency backup. The company claims its integrated design makes for easy installation while the system is password-controlled through a simple touchscreen interface.

Like other products on the market, Powerlegato consists of lithium-ion battery modules, charger, inverter, battery management system and energy management system. AUO claims that according to market research, its product can store an average of 25% more energy per kilogram of weight than its competitors.
