Description
Key Features
- LiFePO₄ Chemistry: Safer (no thermal runaway/fire risk), thermally stable, eco-friendly, and durable in tropical/humid conditions.
- Smart BMS: Built-in Battery Management System with overcharge/over-discharge, overcurrent, short-circuit, temperature protection; includes breaker/fuse for added safety.
- High Cycle Life: ≥6000 cycles to 80% capacity (at 25°C, typical 80–95% DoD)—often marketed as 6000+ cycles with 10–15 year lifespan.
- Expandable: Modular design; stack/parallel compatible (e.g., up to 15.36kWh in some series like M5000).
- Monitoring: Some variants support WiFi/app for remote status (voltage, SOC, health).
- Installation: Wall-mounted or floor-mounted; plug-and-play in kits.
- Other: Low self-discharge, fast charging, wide temp range; UN38.3 certified.
