All-Day Powerhouse: 8,000+ Cycle Life, 17kWh for 24H Heavy Usage!

Equipped with a JK-brand 200A BMS

✅ Multi-Layer Protection: Overcharge/over-discharge prevention, over-current protection, thermal runaway safeguards, and real-time cell balancing.

✅ Precision Monitoring: Track voltage, temperature, SOC (State of Charge), and health status via the intuitive LCD display or DELIGREEN’s BATTERYMONITOR software (compatible with Windows/macOS).

✅ Seamless Compatibility: Pre-programmed with multi-brand inverter protocols (e.g., Goodwe, Growatt, Victron) for hassle-free integration with your existing solar setup.

Why JK BMS Matters:

• Reduces risk of battery damage and extends lifespan.
• Provides 24/7 alerts for anomalies (e.g., short circuits, overheating).
• Simplifies troubleshooting with wireless Bluetooth connectivity.

Integrated Air Circuit Breaker: Lightning-Fast Safety Response

Unlike traditional fuses, the YC-280 features an air circuit breaker built into the BMS:

✅ Instantaneous Shutdown: Trips automatically in case of overcurrent or short circuits, preventing catastrophic failures.

✅ Manual Reset: Quickly restore power with the press of a button—no tools required.

✅ Enhanced Durability: Rated for 200A continuous discharge (51.2V @ 25°C), ensuring stable performance even under heavy loads.

**Why an Air Circuit Breaker?**

• Eliminates fire hazards caused by electrical surges.
• Meets global safety standards (IP20 rating, -20°C to 60°C operating range).
• Reduces downtime compared to fuse-based systems.
