Our rack-mount battery energy storage systems feature LFP cells (280Ah/314Ah), intelligent built-in BMS, RS485/CAN communication, and 6000+ cycle life. Stack 3 to 14 modules to build exactly the capacity you need — from 20kWh up to 225kWh per cabinet. CE/IEC/UL/UN38.3 certified for global deployment.
3–14 Modules · 20–225kWh
Each rack-mount BESS starts with a single 51.2V module (5.12–16.1kWh) and stacks up to 14 modules vertically. Supports up to 16 units in series for even larger installations. Choose from 100Ah, 120Ah, 280Ah, or 314Ah cell configurations. Mix and match voltages (51.2V–716.8V) to meet any system requirement. The modular architecture means you only pay for the capacity you need — and can expand later without replacing existing hardware.
Intelligent BMS · CAN/RS485
Every module includes a built-in Battery Management System providing: cell balancing, intelligent charge/discharge control, capacity retention calculation, isolation protection, and comprehensive alarm management. Real-time monitoring of current, voltage, temperature, SOC and SOH via RS485, RS232, or CAN communication. The BMS ensures safe operation with over-voltage, over-current, high/low temperature, and short-circuit protection — meeting CE, IEC, and UL safety standards.
6000+ Cycles · 15-Year Design Life
Built on first-tier LiFePO4 (LFP) cells rated at 280Ah or 314Ah (3.2V), the rack-mount series delivers >6000 cycles at 80% DOD (0.5C/0.5C, 25°C). The inherent thermal stability of LFP chemistry eliminates thermal runaway risk, while 15+ year design life ensures long-term ROI. Electrical design redundancy exceeds 20% for all models. Working temperature range: 0°C to +50°C (charge), −10°C to +50°C (discharge).
Every model is built from the same 51.2V module base. Stack more modules for higher voltage and capacity. Both 280Ah and 314Ah cell options available across all voltage tiers.
