Product Description
3U High Voltage Rack BMS 176S 563.2V 125A
Compact, intelligent battery management system for solar PV storage, UPS backup, and microgrid applications. Supports parallel operation, external HMI, RS485/CAN/Ethernet communication, and CE certified.
Product Overview
The GCE 3U High Voltage Rack Battery Management System (RBMS) is a compact, intelligent, and highly reliable solution designed for industrial & commercial energy storage, UPS backup power, solar PV systems, and microgrid applications. With a rugged 19-inch 3U rack-mount design, this BMS delivers seamless battery monitoring, protection, and communication for lithium iron phosphate (LFP) battery packs up to 750V.
Whether you need a standalone system or a multi-cluster parallel setup, the RBMS offers flexible architecture (2-level or 3-level) to meet your project scale - supporting up to 200 cells in series and automatic circulation control for safe expansion.
Key Applications
- Solar PV power plant storage
- Off-grid / island energy storage
- PV + storage + charging integration
- Microgrid systems
- UPS backup power
- 220V DC power supply for power systems
