High-Voltage Commercial Storage at Scale — JKBMS ESS120-A1 120kWh All-in-One BESS
The JKBMS ESS120-A1 integrates a 120kWh LiFePO4 battery bank, a 60kW bidirectional inverter, active balance BMS, intelligent air cooling, and multi-level fire suppression into a single IP55-rated outdoor cabinet. Operating at 384V DC, it's designed for industrial parks, commercial complexes, and microgrid applications that require higher power and capacity than standard low-voltage systems — with the same plug-and-play simplicity.

Key Advantages
⚡ High-Voltage Architecture — 60kW at 384V DC
The 384V high-voltage DC bus enables 60kW inverter power in a single cabinet — delivering more power per unit footprint than low-voltage systems. Ideal for applications requiring sustained high-power discharge: fast EV charging buffers, large commercial backup loads, and industrial peak shaving at scale.
🔥 Multi-Level Fire Suppression — Industrial Safety Standard
Three independent fire suppression layers protect against thermal events at every level: PACK-level perfluorohexane, compartment-level aerosol, and an external water fire suppression interface. Combined with an explosion-proof cabinet and IP55 outdoor rating, this system meets the safety requirements of industrial site operators and commercial building managers.
📶 Full Connectivity — EMS & SCADA Ready
RS485 and CAN as standard, with optional WiFi, 4G, and LAN for remote monitoring and unattended operation. Integrate with existing energy management systems or cloud monitoring platforms for full multi-site visibility.
📈 Parallel Scalable — Grow Beyond 120kWh
Multiple ESS120-A1 units can be connected in parallel to expand capacity as your energy needs grow — without replacing existing hardware or redesigning the system architecture.
Application Scenarios
- 🏭 Industrial parks — peak shaving, valley filling, demand charge management
- 🏢 Commercial complexes — backup power and solar PV self-consumption
- 🚗 EV charging stations — high-power buffer storage for fast charging infrastructure
- 🔌 Microgrids — grid stabilization and renewable energy integration
- 🌍 Remote off-grid sites — standalone power supply for industrial operations
