It is highly adaptable to areas with prominent peak-valley electricity price differences and volatile daily load curves. By performing peak-valley arbitrage, it effectively reduces regular electricity expenses. Meanwhile, it optimizes transformer capacity and load regulation to achieve comprehensive power consumption cost reduction.
2. Superior Safety & Ultra-Long Service Life
The system adopts high-quality CATL LiFePO4 battery cells with a cycle life of over 6,000 times, delivering outstanding safety, stability, and weather resistance. Equipped with an IP54 dustproof and explosion-proof cabinet, it integrates a complete set of fire suppression, smoke, and gas detection systems. The intelligent liquid cooling system maintains a cell temperature difference within 3–5°C, effectively preventing battery attenuation and operational risks, ensuring long-term stable and reliable all-weather operation.
3. Intelligent Management & High-Efficiency Operation
Powered by advanced Battery Management System (BMS) and Energy Management System (EMS), together with cell balance technology and a visual HMI interface, the system monitors battery status, charge-discharge data, and operating parameters in real time. It intelligently optimizes charge and discharge strategies and supports remote monitoring, parameter adjustment, and unattended operation. In addition, it integrates AVC and AGC grid frequency regulation functions to smooth power output, shave peaks and fill valleys, and meet refined grid dispatching requirements.
4. Eco-Friendly & Energy Self-Sufficiency
Fully compatible with solar charging systems, the solution builds a complete PV + energy storage power supply mode. It replaces traditional grid power with clean renewable energy, greatly reduces carbon emissions, and enables households and enterprises to achieve energy self-sufficiency and green low-carbon operation.
5. Modular & Highly Expandable Design
Adopting a standardized all-in-one modular structure, the system supports flexible single-unit configuration and allows up to 16 units in DC parallel connection, expanding the total system capacity to over 2.4MWh. It realizes seamless switching between on-grid and off-grid modes and can form hybrid microgrids with solar, wind, and other new energy sources. The flexible scalable design adapts to diversified power demand scenarios of different scales.

Precautions
• No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.
• Please check the orientation of the positive and negative terminals before packaging.
• Connect the terminal or wire to the battery module, and pay attention to insulation to prevent short circuits.
• When not in use for a long time, the battery should be stored in a cool and dry place (<35°C, 30%~50% SOC, charge and discharge once every 3 months).
• Do not place the battery in direct sunlight or a heat source.
• Do not wear metal jewelry (such as rings, watches, accessories, etc.) when handling the battery unit.
Prohibited Matters
Do not charge beyond the maximum charging rate.
