Description

⚡ General Overview

• Brand: Cola Solar (ColaSolar)
• Model: 15 kWh 48 V LiFePO₄ Battery
• Battery Type: Lithium Iron Phosphate (LiFePO₄) — known for safety, long cycle life, and stability.

📊 Electrical Characteristics

• Nominal Voltage: 48 V (often using 51.2 V nominal LiFePO₄ configuration)
• Total Energy Capacity: 15 kWh (15,000 Wh)
• Rated Capacity (Ah): ~300 Ah @ ~51 V nominal (varies by exact cell configuration)
• Chemistry: LiFePO₄ — safer and longer lasting than many other lithium types.

🧠 Performance & Cycle Life

• Cycle Life: Typically ≥6,000 cycles @ 80 % Depth of Discharge (DoD) — meaning many years of frequent charge/discharge use before significant capacity loss.
• Depth of Discharge (DoD): ~80–90 % recommended for best life.

⚡ Voltage & Operating Range

• Nominal Voltage: ~51.2 V (typical for a 48 V LiFePO₄ system)
• Operating Voltage Range: ~40 V – 58.4 V (approximate)
• Recommended Charging Current: ~150 A (varies by exact battery pack)
• Max Charge/Discharge Current: ~200 A (may vary by model)

🔒 BMS & Safety Features

• Built-in Intelligent BMS (Battery Management System):
– Protects against ■ Over-charge ■ Over-discharge ■ Over-current ■ Over-temperature ■ Short-circuit ■ Reverse polarity
• Safety Certifications: Often includes UN38.3 / MSDS (varies by supplier)

🛠 Physical & Environmental

• Dimensions: ~680 × 280 × 830 mm (size may vary slightly by batch)
• Net Weight: ~54 kg (depending on exact cell configuration)
• Mounting: Floor or rack mount (some units include wheels for portability)
• Operating Temperature: Charging ~0–45 °C; Discharging ~-20–60 °C (varies by model)
• Humidity: ~10 – 90 % RH (no condensation)

📡 Connectivity & Monitoring

• Some models offer LCD displays, CAN/RS485/RS232 communication, Wi-Fi/Bluetooth monitoring interfaces (depends on exact variant).

🔌 Compatibility & Expandability

• Parallel Expansion: Supports multiple units in parallel (e.g., up to 16 batteries for ~128 kWh total) — useful for scaling storage capacity.
• Inverter Compatibility: Works with many hybrid and solar inverters (brands like Victron, Deye, GoodWe, Growatt, etc.) (varies by exact battery model).
