The SigenStack Battery 12.0 kWh is the modular LiFePO₄ battery module at the heart of the Sigenergy SigenStack commercial and industrial energy storage system. Each module delivers 12.006 kWh of nominal energy at a nominal 0.5C charge/discharge rate, with a peak rate of 1C. Between 4 and 21 modules can be stacked per system, giving a scalable capacity range from approximately 48 kWh up to 253 kWh — precisely sized to project requirements without over-specifying. Modules stack and connect without cranes or specialist lifting equipment, keeping installation straightforward on commercial rooftops and in plant rooms. IP66-rated enclosures provide full weather protection, and pack-level fire suppression with cell thermal runaway control delivers the safety standard required for commercial deployments. CAN-bus communication ensures seamless integration with Sigenergy's M1-HYA hybrid inverter and Battery Controller.
