GCE 160S512V 250A LFP System BMS High Voltage Battery Management System
160S 512V 250A Master Slave High Voltage BMS | 4U Rack Mount Battery Management System for LFP NCM LTO UPS ESS Off-Grid Microgrid Solar BESS
Product Overview
Our RBMS07-S20-250A512V 4U high-voltage rack BMS adopts a mature three-layer BMU+RBMS+SBMS master-slave distributed architecture, perfectly matching 16-series lithium modules to build a full 160S 512V 250A energy storage system. Compatible with LiFePO4, NCM, and LTO lithium cells, this industrial-grade battery management system serves multiple energy scenarios including large-scale commercial ESS, household energy storage, off-grid solar power stations, carport solar systems, microgrids and industrial UPS backup power.
The complete HV BMS kit contains 1 main master unit + 10 slave BMUs plus matched sampling harnesses; an extra SBMS master cluster controller is supplied for multi-cabinet parallel expansion to realize cross-rack unified communication and coordinated operation. Built per our official 4U two/three-wire RBMS specification V2.0, all hardware uses industrial-grade components with CE & RoHS certification for global energy projects.
Complete HV 160S 512V 250A BMS Full Kit Configuration
Full standard package for 160S 512V 250A energy storage system:
