Energy Storage Systems
TURN-KEY ESS SOFTWARE & HARDWARE THAT PERFORMS
Safe & Reliable Hardware
With over a decade of energy storage experience, Powin has built over 2,500 MWh of systems and has an awarded and contracted pipeline to supply over 10,000 MWh of energy storage systems globally over the next five years. With over 500,000+ hours of incident-free operations, we have developed a proven track record of safe, reliable hardware operations in the field.
Superior Platforms
Our enclosures and modular platforms provide the optimal working conditions for our DC Battery Stacks™ to thrive. Each enclosure comes fully integrated with HVAC, gas detection, fire suppression, DC Collection, AC panel, and communications. The evolution of our Centipede™ Platform offers a factory built, modular platform incorporating all the forementioned safety and controls; requiring less time to install, less space on site, less capital investment, lower total cost of ownership with optimal reliability.  Â
Unprecedented Visibility and Control
StackOS™ is purpose designed for utility-scale stationary energy storage applications and is the most advanced battery management system in the energy storage industry. Combining the Energy Management System (EMS) and Battery Management System (BMS) functionality into a single platform, StackOS™ provides our customers with full control and transparency of the entire system, down to the cell level.Â
