Sustainable Energy Technologies (TSX VENTURE:STG), ("Sustainable Energy" or the
"Company") is pleased to report that interest in the BiDirex(TM) enabled
Sonnenbatterie "Comfort" line of grid parallel solar storage systems was far
greater than the Company expected at last week's Inter-solar show in Munich

"Based on new customer feedback, we now believe that the product mix will be
biased heavily towards three phase systems with mid range power ratings," said
Brent Harris, CTO of the Company, who provided technical support to Prosol
Invest's marketing team in Munich. "Since each three phase Sonnebatterie system
requires three BiDirex(TM) units, this change in demand mix would increase our
unit sales count beyond earlier expectations," Harris added.

Prosol Invest also announced a cooperation agreement with Solarwatt GmbH that
will see the BiDirex(TM) enabled Sonnenbatterie system integrated into the
Solarwatt Solar Power Storage system. Readers are referred to news releases
issued by Solarwatt and Prosol Invest concerning the cooperation agreement:

-- See Solarwatt GmbH news release dated June 17, 2013 and entitled "SOLARWATT

-- See Prosol Invest news release dated June and entitled "PROSOL Invest liefert
intelligentes Lithium-Speichersystem an SOLARWATT" at the Sonnenbatterie website
