Deye BOS-B-PDU-2-A BMS Control Box for BOS-B Battery System

The BOS-B-PDU-2-A is the high-voltage control box that manages a Deye BOS-B battery cluster: it collects the data from each module BMS, operates the DC breaker, handles insulation monitoring and emergency shutdown, and talks to the PCS. Without this unit the cluster cannot be connected to the inverter.

It is built for commercial and industrial installations, storage rooms and peak-shaving systems. It works with BOS-B-Pack14.3 modules (51.2V, 280Ah, 14.3kWh), 5 to 15 in series for a cluster up to 215kWh at 768V, and with Deye three-phase C&I PCS and inverters. An LCD display, status LEDs and Bluetooth app access make field diagnostics straightforward.

Key features

Heart of the BOS-B clusterMaster BMS, 1000V/168A DC breaker and all communication interfaces in a single cabinet.
Wide voltage windowOperates from 200 to 1000V DC, covering clusters from 5 up to 15 BOS-B-Pack14.3 modules in series.
High-voltage safetyInsulation monitoring, EPO interface for emergency shutdown and dedicated high-voltage warning indicators.
Instant diagnosticsLCD display with SOC and fault codes, status LEDs and TCP, RS485 and CAN communication to the PCS.
