Product Overview
Designed for heavy-duty industrial energy storage, this 261kWh battery system integrates high-performance aluminum-housed LiFePO4 cells through tailor-made series-parallel stacking design. It provides dependable, safe power with long cycle life to satisfy high electricity demands for various industrial and commercial operations. This energy storage solution is well-suited for commercial solar storage, standalone off-grid power facilities, plant emergency backup systems, temporary construction power stations and heavy industrial equipment. Differing from ordinary battery packs, it comes with negligible standby energy drain, strong mechanical and chemical stability, alongside precise capacity readout, fully covering continuous industrial power supply and emergency energy backup needs.
Core Advantages
Top-Tier Grade A Cells
Brand-new industrial aluminum-cased LiFePO4 cells are deployed in this system. The refined housing structure optimizes heat dissipation and offers outstanding protection against rust and corrosion, lengthening the total service lifespan of the battery system.
Consistent Charge-Discharge Performance
It supports stable 0.5C-rate operation and sustained constant current output. The unit can run nonstop for long durations without current swings or thermal overheating, delivering trustworthy power supply for industrial loads.
Robust High-Power Startup Performance
It can produce instant surge current within 3 seconds, catering to the short-duration high-load startup requirement of different high-power electrical and mechanical machinery.
Ultra-Low Standby Energy Drain
Standby power draw is capped below 10mA to slow down self-discharge. The battery can hold sufficient energy reserve even after extended idle storage.
High-Accuracy SOC Detection
Built-in intelligent BMS performs real-time status tracking and keeps SOC deviation within 2%. It displays remaining capacity accurately so operators can quickly judge battery working conditions.
High Safety & Reliability
The intrinsically safe LiFePO4 material will not ignite or explode under abnormal conditions. Multi-tier safety safeguards allow long continuous running with minimal hazard risks.
Application Scenarios
This large-capacity lithium storage system is widely adopted for industrial and commercial solar storage solutions, off-grid power plants, industrial UPS backup power, telecom base station power supply, temporary construction site power stations, and a wide range of medium & large engineering power units and heavy industrial loads.
