Lithium BMS Battery Management System for LiFePo4 Battery ESS UPS Off Grid Solar ESS
Product Overview
The 4U High Voltage Rack Battery Management System (RBMS) is a next-generation master controller designed for large-scale stationary lithium battery storage. Supporting voltages up to 1000V and currents up to 250A, this intelligent system offers flexible 2-wire (standard) or 3-wire (center-tap) configurations. With its robust 19-inch rack-mount design, dual power supply, and advanced (3-level) architecture, it delivers unparalleled safety, scalability, and communication compatibility for commercial and industrial energy storage projects.
Key Features & Technical Advantages
Wide Voltage & Current Portfolio - Available in 150V, 350V, 750V, and 1000V voltage levels with optional rated currents of 125A, 160A, or 250A. Supports up to 256 cells in series (400 for lead-carbon batteries), making it suitable for small UPS systems up to massive utility-scale racks.
Flexible System Architecture (2-Wire / 3-Wire) - Supports both standard two-wire systems (without mid-line) and 3-wire center-tap systems for applications requiring a neutral line. Operates in standalone mode (BMU+RBMS) or parallel cluster mode (BMU+RBMS+SEMS) to manage up to 15 racks simultaneously.
Ultimate Protection & Safety - Equipped with 25kA short-circuit protection (response within 20ms at 1000V), integrated pre-charge function, reverse polarity protection, and an Emergency Power Off (EPO) dry-contact input. Dual power supply (battery + AC mains, with mains priority) ensures uninterrupted operation.
Intelligent Automatic Parallel Control - Built-in automatic circulation suppression and auto-parallel/offline control algorithms eliminate balancing headaches, allowing effortless battery rack expansion without the risk of internal loop burnout.
Comprehensive Data Traceability - Stores up to 5,000 event records internally, with an optional SD card slot for long-term cell history logging. Supports real-time monitoring via an external HMI display (7-inch compatible).
Universal Communication Compatibility - Rich interface suite including RS485, CAN, Ethernet, and dry contact I/O. Pre-supports standard protocols and offers custom firmware adaptation to ensure seamless plug-and-play integration with virtually all PCS, Inverter, and UPS brands on the market.
Rugged Rack-Mountable Design - 4U standard 19-inch form factor (482*180*500mm), front-in/front-out wiring for easy maintenance, IP20 protection, and a wide operating temperature range of -20℃ to 45℃ (with derating above 45℃). CE safety certified (IEC62477-1, EN61000-6-2/4).
