Description

Core Electrical Data

• Nominal Energy Capacity: 15.36 kWh (15,360 Wh) — total stored energy at nominal voltage.

• Nominal Voltage: 48 V (often actual ~51.2 V) system voltage.

• Rated Capacity: 300 Ah.

• Battery Chemistry: LiFePO₄ (Lithium Iron Phosphate) — stable, safe, and long-lasting.

🧠 Battery Management & Protection

• Built-in BMS (Battery Management System):
  Protects against over-charge, over-discharge, over-current, short circuit, and temperature extremes for enhanced safety.

• Communication Interfaces: Commonly RS485 / CAN / optionally RS232 for inverter integration and monitoring (model dependent).

🔁 Cycle Life & Depth of Discharge

• Cycle Life: Typically >6 000 cycles @ 80% DoD — long service life with deep cycling.

• Depth of Discharge (DoD): Commonly rated ~80–90% usable without shortening lifespan.

🔄 Charge / Discharge Parameters

(Typical for 15.36 kWh LiFePO₄ packs of this class)

• Standard Charge Current: ~60 A (varies by model).

• Standard Discharge Current: ~150 A.

• Max Continuous Charge/Discharge: up to ~200 A (battery design dependent).

• Recommended Charge Voltage: approx 56.8 – 58.4 V.

• Charge Cut-off Voltage: ~58.4 V.

• Discharge Cut-off Voltage: ~40–44 V.

🌡 Environmental & Operating Conditions

• Operating Temperature:

  • Charging: ~0 °C to +45 °C

  • Discharging: ~-20 °C to +55 °C

• Storage Conditions: Often ~-5 °C to +35 °C for long-term.

• Humidity: Usually safe up to ~95% non-condensing.

📦 Physical & Mechanical

• Design: Floor-standing or cabinet/narrow rack enclosure; WHC models may be wall-mounted or modular depending on supplier.

• Parallel Capability: Most 48 V 300 Ah packs support parallel expansion (e.g., up to around 10–15 units) for larger total energy storage.

• Weight: Typical range ~100–130 kg depending on build and enclosure.

• Installation: Indoor or sheltered location recommended; avoid direct rain exposure.

🔌 Compatibility & Use Cases

• Hybrid Solar Systems: Works with high-capacity hybrid inverters (48 V) to store solar energy for night use.

• Backup Power: Powers home, office, or light industrial loads during outages.

• Off-Grid & Commercial: Suitable for off-grid solar setups or commercial energy storage solutions.

• Parallel Expansion: Can be linked with additional batteries to scale capacity.

🧠 Safety & Long-Term Performance

• LiFePO₄ cells offer excellent thermal and chemical stability with high safety compared to other lithium chemistries.

• Low Self-Discharge: LiFePO₄ typically has low self-discharge, retaining charge well when idle.

• Maintenance-Free: No watering, ventilation or active cooling in many designs.
