Delta's high efficiency, power-saving technology has received the industry’s recognition once again. Great news was reported back from the 2nd Energy Storage Innovation Competition award ceremony at the China National Convention Center, in which the "energy storage two-way DC power converter module and its series-parallel connection technology" developed by the Delta Energy Storage Technology Team was named the "Top 10 Energy Storage Technologies 2018 " for its outstanding performances in terms of high efficiency, compactness, lightweight and low cost. 

The "energy storage two-way DC power converter module and its series-parallel connection technology" developed by the Delta Energy Storage Technology Team was named the " Top 10 Energy Storage Technologies 2018" in the 2nd Energy Storage Innovation Competition

The Delta Energy Storage Technology Team has extensive experience in power electronics and power-efficient technologies, and has developed the high power, high voltage energy storage system with a two-way DC converter and series-parallel transformer. The device uses a flying tri-level and high frequency modular technology to achieve high efficiency, compactness, lightweight and low cost. The Company's application of the flying tri-level technology is leading the industry. The series-parallel control and self-control realizes plug-and-play, with the number of series-parallel connection reaching 32 units and system power being more than 4MW.

Delta is currently applying various patents for the said technology and has received one certification, and one software copyright. Furthermore, Delta has begun partnerships with renowned international corporations such as CRRC and General Electric Company for the said product and solution. Its market application has a wide and promising outlook.
