Product Overview
Equipped with high-grade aluminum casing lithium iron phosphate cells and a professional series-parallel assembly structure, this upgraded large-capacity industrial energy storage battery pack reaches a huge energy storage capacity of 261kWh. It provides consistent, secure and ultra-long cycle power output, catering to high-power power supply demands in industrial and commercial scenarios. This battery solution is ideal for industrial & commercial solar energy storage, off-grid power stations, factory emergency backup power, construction site power supply and heavy-duty industrial power equipment. Different from conventional battery products, it features extremely low standby power consumption, superior structural and chemical stability, as well as precise power display function, fully meeting continuous industrial power supply and emergency power reserve requirements.
Core Advantages
High-Quality Grade A Cells
Configured with brand-new aluminum-shell LiFePO4 cells of industrial grade. The optimized shell structure delivers efficient heat dissipation and outstanding corrosion and rust resistance, effectively prolonging the overall service life of the battery pack.
Stable Charge and Discharge Performance
Supports stable 0.5C rate operation with sustainable continuous current output. It can maintain long-hour stable working status without current jitter, overheating and other abnormal conditions, ensuring reliable industrial power supply.
Excellent High-Power Startup Capacity
Capable of outputting instantaneous surge current within 3 seconds, which perfectly copes with the instantaneous high-load startup needs of various high-power electrical and mechanical equipment.
Ultra-Low Standby Power Consumption
The standby power is controlled below 10mA, which effectively inhibits battery self-discharge. The battery can retain sufficient power reserve even after long-term standby and idle placement.
High-Precision SOC Monitoring
Built-in intelligent battery management system realizes real-time data monitoring, controlling the SOC deviation within 2%. It can accurately display the remaining battery capacity for real-time power status judgment.
Superior Safety & Stability
Adopts safe and stable LiFePO4 raw materials with non-flammable and non-explosive chemical characteristics. With multiple safety protection designs, it supports long-term continuous stable operation with zero safety hazards.
Application Scenarios
This large-capacity industrial lithium battery pack is widely applicable to industrial & commercial solar energy storage systems, off-grid power supply stations, factory UPS emergency backup power, communication base station power supply, construction site power stations, and various medium and large engineering power equipment and heavy-duty industrial loads.
