Q1: Is professional installation required?
A: Yes. As a high-voltage energy storage system involving high-voltage wiring, grid connection commissioning and safe operation, it must be installed by a professional team with power engineering qualifications to ensure safe and stable operation.
Q2: What if battery voltage deviation or rapid capacity fading occurs during operation?
A: The system is equipped with a high-precision BMS intelligent balancing system that automatically calibrates cell voltages and optimizes cell consistency to reduce capacity decay. Daily inspections and regular SOC/SOH calibration effectively avoid such issues and ensure long-term stable battery performance.
Q3: Will the system malfunction under extreme temperatures?
A: No. The system supports wide-temperature operation (discharge: -20℃~+60℃, charge: 0℃~+55℃) with a liquid cooling system that intelligently regulates cabinet temperature and controls temperature difference ≤3–5℃. It automatically derates at high temperatures and preheats at low temperatures to prevent temperature-related failures.
Q4: What is the operating temperature range?
A: Discharge: -20℃~+60℃, Charge: 0℃~+55℃, optimal operating temperature: 20℃~30℃, balancing operational stability and battery life.
Q5: What safety protections does the system have against leakage, overheating and other hazards?
A: Full-range safety protection is provided to effectively eliminate risks. It includes an FK-5-1-1-2 fire suppression system, multi-dimensional detection (temperature, smoke, flammable gas), as well as over-temperature, over-charge, electric leakage and liquid leakage protection. Abnormal conditions automatically trigger isolation, alarm and fire extinguishing linkage.
Q6: Will communication failures or parameter mismatch occur during multi-cabinet parallel expansion?
A: No. The system supports parallel expansion to MWh-level with a unified voltage platform and BMS/EMS communication protocol. Parameter matching and commissioning are completed before delivery, avoiding communication interruptions and mismatches for convenient and stable expansion.
