BMS Control box for BOS-G HV system

BMS control unit for BOS-G high-voltage battery systems with simple installation in a 19" rack. It has detailed management, high reliability and a built-in display. With its help, it is possible to create a battery cluster containing 3 to 12 batteries in series with a total capacity of up to 61.44 kWh. Protection functions including overdischarge, overcharge, overcurrent and too high or low temperature are a matter of course. The system automatically charges, monitors the state of charge and capacity, balances voltage and current across all connected battery modules to ensure optimal operation of the entire storage.

ATTENTION! This is a separate control unit without batteries! Batteries must be purchased separately!
