Description

Product Description
The Deye BOS-B HV battery module is a high-voltage energy storage unit intended for use in large battery banks with series stacking architecture. Each module offers 14.3 kWh of usable energy and incorporates an integrated Battery Management System (BMS) for cell monitoring, balancing, and multi-layer protection against over-charge, over-discharge, over-current, and over-temperature conditions. The modular design allows multiple BOS-B units to be stacked and controlled by a BOS-B cluster control box to form larger high-voltage energy storage systems, suitable for commercial, industrial, and advanced residential installations when paired with an appropriate rack system and hybrid inverter. BOS-B modules are scalable, communicative with system controllers via CAN or RS485, and compatible with high-voltage inverter platforms.
