Sustainable Energy to Introduce Breakthrough "bi-direx" Energy Storage Inverter to Japan at Renewable Energy 2013, in Tokyo, July 25-26, 2013

CALGARY, ALBERTA--(Marketwired - July 23, 2013) - Sustainable Energy Technologies (TSX VENTURE:STG), ("Sustainable Energy" or the "Company"), announced today that it will introduce its breakthrough "bi-direx" energy storage inverter at the Renewable Energy 2013 Exhibition in Tokyo Japan (booth R02-018) http://www.renewableenergy.jp/english/index.html), July 24 - 26, 2013.

Bi-direx is a bi-directional smart grid inverter designed specifically to connect low voltage battery and fuel cell systems to the power grid with very high conversion efficiencies. Sustainable Energy's business model is to partner strategically in high growth markets to create high value added energy storage solutions for smart grid and micro-grids by delivering a software configurable platform that allows maximum control over inverter functionality to simplify system design, reduce cost and maximize speed to market.

In Europe, the bi-direx inverter is powering the market leading Sonnebatterie by Prosol Invest Deutschland GmbH, which was recently introduced to the North American market at Intersolar North America in San Francisco July 9 - 11 2013.
