Built with safe, high energy density, prismatic Lithium-Iron-Phosphate cells, this battery produces power that you can depend on. It also features built-in data storage and Wi-Fi for remote monitoring and troubleshooting abilities. The smart, relay-based Battery Management System (BMS) supports closed-loop communication with numerous 48V hybrid inverters. Additionally, the BMS monitors and balances the voltage and temperature of each individual cell to maximize reliability and longevity. The Fortress Power eFlex 5.4kWh Lithium Iron Phosphate Battery has wall mounting functionality and fits well into standard server racks for larger systems.
