I Product Features
1.High Energy Density and Long-Life Battery Configuration
Utilizing 3.2V/314Ah celltechnology,the system adopts a 12P(1P1045*4)battery configurationto achieve a total battery capacity of 5.0MWh.This design accomplishes high energy densitystorage within a compact 20-foot space while minimizing footprint.The cells feature extendedcycle life characteristics,significantly reducing long-term usage costs and replacementfrequency.
2.Precise andIntelligent BMS System
Equipped with an advanced Battery Management System(BMS),it enables real-time andprecise monitoring and control of battery parameters through LAN/RS485 communicationinterfaces using TCP/IP and MODBUS protocols.The system promptly detects abnormalitiessuch as overcharge,over-discharge,and overtemperature,and implements swift protectivemeasures to ensure battery safety and extend battery lifespan.
3.Efficient and Stable Power Conversion
With an AC-side rated power of 2500kW,AC current distortion rate <3%(at rated power),DCcomponent <0.5%,it demonstrates highly efficient and stable power conversion capabilities.Under the 690VAC-side rated voltage,it adapts to grid voltage ranges of 586.5V-759V,achievinga power factor>0.99(at rated power).This effectively enhances power quality and reduces linelosses.
4.High Protection and Wide Temperature Adaptability
With IP55 protection rating,it effectively resists external hazards like dust and water splashes,adapting to harsh environments.The operating temperature range is-30℃ to 50℃(with a 45℃temperature limit),and operating humidity range is 0%to 95%(non-condensing).Even underextreme climatic conditions,the Intelligent Temperature Control System(liquid cooling forbattery compartment,air cooling for inverter)ensures stable equipment operation.
