Product Overview
Our industrial-scale energy storage battery system uses premium aluminum-encased lithium iron phosphate cells, integrated via customized series and parallel layout. The system achieves a total storage capacity of 261 kWh, delivering stable, secure power output with excellent cycle endurance. It addresses high-power consumption requirements for a wide range of industrial and commercial use cases. This battery system serves as an ideal power solution for industrial and commercial solar storage, standalone off-grid power plants, factory emergency backup power, temporary construction-site power and heavy industrial machinery. Compared with conventional battery products, it features minimal standby power loss, robust structural and chemical stability, plus accurate remaining capacity display, to meet continuous industrial power supply and emergency energy reserve demands.
Core Advantages
Premium Grade A Cells
This system adopts brand-new industrial-grade aluminum shell LiFePO4 cells. The optimized housing design enhances heat dissipation and delivers strong anti-corrosion and anti-rust performance, effectively extending the whole pack service life.
Stable Charging & Discharging Characteristics
It supports steady operation at 0.5C rate and maintains continuous constant current output. The system can run for extended hours without current fluctuation or overheating faults, ensuring reliable power delivery for industrial loads.
Powerful High-load Start-up Capability
It can generate instant surge current within 3 seconds to meet the momentary high-current startup demands of multiple high-power electrical and mechanical devices.
Minimal Standby Power Loss
Standby power consumption is limited under 10mA to reduce self-discharge. The battery retains ample stored energy even after long idle standby periods
High-precision SOC Measurement
An integrated smart BMS carries out real-time data monitoring, limiting SOC deviation within 2%. It can show residual capacity precisely for quick assessment of battery operating status.
High Safety and Stability
It adopts intrinsically safe LiFePO4 raw material with non-flammable and non-explosive characteristics. Multi-layer safety protection enables long-term continuous operation with low safety risks.
Application Scenarios
This large-capacity lithium battery pack is widely applied in industrial & commercial solar storage systems, off-grid power stations, industrial UPS backup power, telecom base station power supply, temporary construction power stations, as well as medium & large engineering power equipment and heavy industrial loads.
