High Voltage BMS GCE Battery Management System 128S409.6V 50A HV BMS Master Slave BMS for LiFePO4 ESS UPS Substation Switchgear

GCE 2U HV RBMS Master Battery Management System

High Voltage BMS GCE Battery Management System 128S409.6V 50A HV BMS Master Slave BMS for LiFePO4 ESS UPS Substation Switchgear

Product Overview

GCE 2U Rack-Mounted HV RBMS serves as the core master battery controller tailored for large-scale high-voltage lithium energy storage and UPS equipment. Built on a distributed, modular, three-tier BMU+RBMS+SBMS architecture, this rack BMS supports DC systems up to 500V with flexible deployment modes to match project capacity tiers from small household storage to megawatt-level containerized energy power stations.

Dual-layer standalone architecture (BMU + RBMS): Ideal for small-scale 10kWh-100kWh commercial & residential energy storage cabinets
Three-layer multi-cluster parallel architecture (BMU+RBMS+SBMS): Suitable for medium-to large projects of 50kWh-2MWh, supporting parallel connection of up to 15 RBMS units
Four-layer power station system: Scales seamlessly for large 2MWh-1000MWh PV power plant energy storage projects

Core Competitive Advantages

Distributed Modular Expandable Design, Wide Series Compatibility

Standardized 2U 19-inch rack structure with front-in/front-out wiring for easy cabinet installation, commissioning, and maintenance. Modular combination supports flexible expansion of energy storage capacity, compatible with LiFePO4, NMC, and LTO lithium cells, monitoring up to 160 cells in series.

All-Round Multi-Level Safety Protection & Accurate Sampling

Full battery protection logic including overcharge, over-discharge, over-temperature, over-current, and short-circuit defense (6KA short-circuit protection within 20ms). Current sampling precision reaches 1%FSR, with 2800VDC insulation withstand voltage to eliminate high-voltage leakage risks.

Rich Multi-Channel Communication & Cross-Brand Inverter Compatibility

Standard CAN, RS485, Ethernet LAN, and dry contact IO ports. Supports proprietary factory communication protocol and customizable protocol adaptation for mainstream inverter brands including Deye, Growatt, Goodwe, Sungrow, ATESS, Megarevo and Pylontech.

3.5-inch Embedded HMI & Massive Historical Data Storage

Built-in integrated 3.5-inch touch screen visualizes real-time voltage, current, temperature, and system fault alerts. Large-capacity onboard memory records up to 5000 system event logs with optional SD card slot for long-term data backup.

Wide Environmental Adaptability & Authorized Safety Certification

Operates stably under -20℃~60℃ working temperature and 5%-75%RH humidity. Passed CE certification compliant with IEC62477-1 EMC standards with IP20 protection grade for indoor rack cabinet installation.
