The HB-M2K is a high-voltage stacked energy storage lithium battery using safe, stable LiFePO4 cells (LFP 54Ah), offered in three capacities — 11.05, 13.82 and 16.58 kWh — across a high-voltage platform from 204.8V to 307.2V. It supports CAN/RS485 communication and flexibly matches high-voltage inverters or energy storage PCS units, making it suitable for residential storage, small-shop backup, PV self-consumption and standby power systems. The compact floor-stacked design saves space and simplifies installation, while IP65 protection on both inverter and battery, reverse-polarity and over-current/voltage protection, and CE, RoHS and UN38.3 certification ensure dependable outdoor-ready operation.
