Introduction

1.Highly Integrated All-in-One Design: Integrates LFP (lithium iron phosphate) battery, BMS (Battery Management System), PCS (Bi-directional Power Conditioning System), EMS (Energy Management System), intelligent thermal management and advanced fire protection system into a single standard cabinet. The compact structure saves installation space, supports plug-and-play installation, and the overall deployment cycle is only 1-3 days, greatly improving the efficiency of project construction.

2.Superior Power & Large Capacity: Rated power reaches 125kW, rated energy capacity is 261kWh, with 0.5C standard charge-discharge rate (supporting 0.2C-1C flexible adjustment). The system’s overall efficiency is no less than 92%, and the cycle life is up to 6000+ times (equivalent to 10-12 years of service life), which can stably meet the long-term high-power, large-capacity energy storage needs of industrial and commercial users.

3.High Safety & Wide Environmental Adaptability: Equipped with IP54/IP55 dustproof and waterproof grade, and C5 anti-corrosion treatment, suitable for harsh working environments. Built-in multi-level safety protection mechanisms, including smoke detector, temperature sensor, heptafluoropropane/aerosol automatic fire suppression system, cell-level fire protection and cluster-level isolation. It can operate stably in a wide temperature range of -25℃ to 60℃, adapting to both indoor and outdoor deployment.

4.Intelligent Management & Easy O&M: Equipped with a high-performance local EMS and a remote cloud monitoring platform, supporting RS485/CAN/Ethernet communication protocols. It realizes millisecond-level grid-connected and off-grid switching (less than 20ms), supports OTA remote upgrade, real-time data monitoring and fault self-diagnosis. The intelligent management system reduces manual intervention, lowers operation and maintenance costs, and ensures the stable operation of the system.

5.Flexible Scalability & Versatile Deployment: Adopts a modular design, which can realize independent operation of a single cabinet or parallel expansion of multiple cabinets to flexibly meet the capacity expansion needs of users (supporting 125kW/261kWh per cabinet, expandable to MW-level capacity). It supports wall-mounted, floor-standing and other installation methods, and is suitable for indoor and outdoor deployment such as factories, industrial parks, shopping malls and remote areas.

Introduction

1.Industrial & Commercial Peak-Valley Arbitrage: It is an ideal solution for large-scale industrial and commercial users (such as large factories, shopping malls, office buildings and industrial parks). It charges with low-price off-peak electricity at night and discharges with high-price peak electricity during the day, making full use of the electricity price difference to significantly reduce the enterprise’s electricity cost. At the same time, it realizes peak shaving and valley filling, reduces the transformer capacity fee, and improves the economic benefits of the enterprise.

2.Emergency Backup Power: With high power and large capacity, it can switch to backup power supply in milliseconds when the grid is cut off, providing uninterrupted and stable power for key loads such as large data centers, hospitals, banks, precision manufacturing equipment and communication base stations. Compared with traditional UPS, it has larger capacity, longer endurance and stronger adaptability.

3.Distributed PV/Wind Power Consumption: It is perfectly matched with large-scale distributed photovoltaic and wind power generation systems. It can store the surplus power generated by PV/wind power, smooth the fluctuation of renewable energy output, improve the self-consumption rate of green power, solve the problem of wind and solar abandonment, and promote the efficient utilization of renewable energy. It is widely used in solar-storage-charging integrated stations, industrial and commercial microgrids and regional energy storage projects.

4.Power Quality Improvement: It can effectively compensate for three-phase unbalance, voltage sag, voltage fluctuation and low power factor in the power grid, stabilize the voltage and frequency of the power grid, and improve the power supply quality. It is suitable for distribution network transformation, precision manufacturing, high-tech parks and other scenarios with high requirements for power quality.

5.Off-Grid & Remote Area Power Supply: It provides a reliable independent power supply solution for areas without grid or with weak grid (such as islands, mines, rural remote areas and border posts). It can operate independently or work with diesel generators and photovoltaic panels to form a microgrid, ensuring the normal power demand for production, living and public services in remote areas.
