Powin Energy Corporation has unveiled three new products, Stack™225, Stack™230 and Stack™230P, its first products utilizing Contemporary Amperex Technology Co. Limited (CATL) battery cells. All three products were designed by Powin around CATL's large form factor cells, utilizing Powin's patented StackOS battery management and controls software.

Powin's proprietary Stack™ products can perform a wide variety of in front of the meter, behind the meter, and microgrid applications to meet today's evolving energy storage needs, yet they are designed to be flexible so that as priorities shift, the battery applications can be adapted to meet the needs of future use cases.

Already in mass production, Powin's Stack™225 product is used for 2-hour duration systems and offers a 10-year, one-full-cycle-per-day performance guarantee. The Stack™230P is a product designed for shorter duration applications such as frequency regulation and other ancillary services. The Stack™230 is Powin's first product released to the market providing a 20-year, one-full-cycle-per-day performance guarantee.
