WE’RE BUILDING THE FUTURE OF ENERGY
Energy Storage Systems
ESS SOFTWARE & HARDWARE BUILT TOGETHER TO WORK BETTER TOGETHER
Safe & Reliable Hardware
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.
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.
With over a decade of energy storage experience, Powin has built over 2,000 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.

How Batteries Store Energy
HERE IS HOW BATTERY ENERGY SYSTEMS WORK
Battery storage solutions are powered by renewable energy sources, such as solar energy. Our advanced technology enables these systems to hold onto this energy and distribute it when the time is right.
Different Applications for Battery Storage
THE WAYS YOU CAN USE OUR SYSTEMS
Emergency Backup: Having our storage system as an emergency backup is key to keeping you online and keeping your systems working in the event of an outage.
Microgrid and Grid Services: Battery storage solutions help you to create your own electric grid that’s not connected to a central power unit. That means that you maintain electricity despite the primary grid going out. Our solutions allow you to stay in control of the voltage, reserve capacity, and much more.
Behind the Meter: Our batteries help you to receive electricity where you need it and when you need it. This allows you to keep costs down by only buying what you require and avoiding unnecessary fees.
Peak Shaving: Lower the electricity use among your customers by setting battery energy storage system specifications as you see fit. This can help you avoid excess electricity coming from the grid at the peak hours of the day.
Load Shifting: Decrease the electricity for a short period before peak timeframes. This keeps energy usage at the same level in general. However, it moves the energy to where you want it to go, which helps you stay in control of costs and energy distribution. This process is especially helpful for utility companies that don’t check meters every year.
Solar Energy Management: By using battery storage, your customers can utilize unused energy from the day at night. That can help optimize energy usage.
