Deye High-Voltage Battery Cluster Control Box (PDU / BMU) – BOS-G Pro
 
The Deye High-Voltage Battery Cluster Control Box, officially designated as Model BOS-G-PDU-2, is a critical system component for Deye BOS-G Pro high-voltage battery installations.

Commonly referred to as the BMU (Battery Management Unit), this unit manages, protects, and controls the complete high-voltage battery cluster while providing communication between the battery system and compatible Deye high-voltage hybrid inverters.
 
The PDU/BMU is installed inside the Deye High-Voltage 3U-H Rack and is mandatory for all BOS-G Pro HV battery systems.
 
Key Functions & Features:
Centralised monitoring and control of the high-voltage battery cluster
Real-time monitoring of voltage, current, temperature, and system status
Protection against over-voltage, under-voltage, over-current, short-circuit, and temperature faults
Battery cluster balancing and fault isolation
Communication with Deye high-voltage hybrid inverters via CAN / RS485
Conforms to European and British safety standards
