CALGARY, ALBERTA--(Marketwired - June 25, 2013) - Sustainable Energy Technologies (News - Market indicators), ("Sustainable Energy" or the "Company") is pleased to report that interest in the BiDirex^™ 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 Germany.

"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^™ 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^™ 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:
