Deye BOS-B-PDU-2-A HV Cluster Control Box for BOS-B Pro

The Deye BOS-B-PDU-2-A is the high-voltage cluster control box for the Deye BOS-B Pro 16.08kWh battery (DEYE-BOS-B PRO-16.08KWH). Every BOS-B Pro cluster needs exactly one.

It sits on top of the module stack and manages the whole cluster: the master BMS, the main breaker and the DC and communication links to the inverter or PCS. A display shows state of charge and fault codes, and IN/OUT COM ports link clusters in parallel.

• Built-in breaker, SOC/fault display and HV/alarm indicators
• Two PCS DC output pairs and battery-to-inverter communication
