Deye BOS-G-PDU-2 Control Box for HV Batteries

Product Description

The Deye BOS-G-PDU-2 Control Box is the heart of Deye high-voltage battery banks. It manages and protects the HV string formed by BOS-G modules, centralizes communication with the inverter, and offers a local monitoring interface via an integrated display. Designed for 19” rack mounting (3U), it combines power electronics, protection, and master BMS to provide safety, stability, and fast commissioning in advanced residential, commercial, and industrial installations.

Main Features

• HV cluster management: governance of the string and orchestration of the module BMS.
• Typical operating voltage range 200–1000 Vdc (depending on the number of modules in series).
• Nominal current 100 A; peak allowed up to 120–125 A under specified conditions.
• Integrated display for system status, alarms, and key parameters.
• CAN/RS485 communications for synchronization with compatible Deye inverters.
• 19” (3U) format for clean integration in the brand’s own LRACK/HRACK racks.

Advantages or Benefits

• Safety and control: centralizes protections and HV string operation logic, reducing risks from wiring or configuration.
• Agile commissioning: native profiles for Deye inverters, fewer adjustments, and reduced commissioning time.
• Total visibility: the local display allows immediate diagnostics without always relying on the portal.
• Scalability: supports different string lengths (e.g., 8/12/16 modules) and expansion via parallel clusters.
• Professional integration: 3U format and interconnection accessories designed for the family’s 19” racks.

Purpose or Applications

The Deye BOS-G-PDU-2 Control Box is aimed at HV storage systems with BOS-G modules in series. It is ideal for commercial self-consumption, industries with demand peaks, on/off-grid microgrids, and C&I projects requiring high availability, precise management, and staged growth.
