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.\n  \u003c\/p\u003e\n\n  \u003cul class=\"feat-list\"\u003e\n    \u003cli\u003e12.006 kWh per module — high energy density in a compact, stackable footprint\u003c\/li\u003e\n    \u003cli\u003e4–21 modules per system — scalable from ~48 kWh to ~253 kWh with no wasted capacity\u003c\/li\u003e\n    \u003cli\u003eLiFePO₄ chemistry — superior thermal stability, long cycle life, and enhanced safety vs NMC\u003c\/li\u003e\n    \u003cli\u003eIP66 rated — suitable for outdoor and semi-exposed plant room installation\u003c\/li\u003e\n    \u003cli\u003ePack-level fire suppression and cell thermal runaway control — commercial-grade safety\u003c\/li\u003e\n    \u003cli\u003eNo cranes required — modules stack and connect by hand, reducing installation cost\u003c\/li\u003e\n    \u003cli\u003eStack-and-play wiring — no complex inter-module cabling; automatic device networking\u003c\/li\u003e\n    \u003cli\u003eCAN-bus integration — direct communication with Sigen M1-HYA hybrid inverter and BC\u003c\/li\u003e\n    \u003cli\u003eDC-coupled design — up to 2% better round-trip efficiency versus AC-coupled alternatives\u003c\/li\u003e\n    \u003cli\u003eDimensions: 768 × 195 × 363 mm · Weight: 107 kg\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cdiv class=\"callout callout-blue\"\u003e\n    ℹ️ \u003cstrong\u003eSystem build:\u003c\/strong\u003e A complete SigenStack installation requires: one MAIN base unit (SIG-STACK-BASE-MAIN-0.5C), one Battery Controller (SIG-STACK-BC-M2-0.5C-BST), the required number of battery modules (this SKU), and the Sigen M1-HYA hybrid inverter.
