Description
The Deye BOS-A HVB 800V/160A-EU control module (BOS-A-PDU-2) is the central management unit for high-voltage (HV) energy storage systems in the Deye BOS-A / V-TAC BOS-A range. It provides communication, protection, coordination and control of battery modules in a rack configuration, managing both charging/discharging and real-time monitoring of the system.
With an operating range of 200–1000 Vdc, a maximum charge/discharge current of 160 A, IP20 protection and intelligent communication ports, the module is ideal for industrial, commercial and residential applications with high performance requirements.
