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 (51.2 V, 280 Ah, 14.3 kWh), 5 to 15 in series for a cluster up to 215 kWh at 768 V, and with Deye three-phase C&I PCS and inverters. An LCD display, status LEDs and Bluetooth app access make field diagnostics straightforward.
