20 Foot ESS Container | 3.06 MWh
On this page:
The Legion C20 containerized energy storage system by ETICA embodies a cutting-edge approach to energy storage solutions. With a storage capacity equivalent to a standard 40-foot container in half the size, its modular design not only optimizes project timeline and budget but also maximizes efficiency.Â
Featuring advanced immersion cooling battery technology, state-of-the-art fire-suppression mechanisms, and an in-house Master Battery Management Unit (MBMU), the Legion system sets a new standard for safety and intelligence in the realm of energy storage solutions.
Patented Immersion Cooling
Battery cells are submerged in non-toxic dielectric oil for direct active thermal management, fire suppression, and propagation prevention.
Active Thermal Management
Our Battery Management System (BMS) monitors temperature and responds with liquid cooling circulation, enhancing heat exchange.​​
Integrated BMS & EMS
Our non-Chinese BMS and EMS ensure optimal performance, safety, and efficiency, offering unmatched reliability and control.
Enhanced Durability
Our battery modules have an IP65 rating while our cabinet is rated at IP54, ensuring reliable performance in demanding environments.
