SOFAR CBS5000-BCU control module + base

CBS5000-BCU – Central Battery Control Unit (High-Voltage)

The CBS5000-BCU is a central control unit (Battery Control Unit) designed to manage CBS5000-BMU high-voltage battery modules. It is responsible for monitoring the operation of the entire battery stack, system security, and communication with the Sofar hybrid inverter. The BCU enables the construction of flexible energy storage configurations – from several modules in a single cabinet to extensive systems with capacities reaching hundreds of kWh by connecting cabinets in parallel.

The unit operates within a voltage range of 600–1000 V DC, ensuring high system efficiency and compatibility with Sofar industrial inverters (e.g., the HYD series). Integrated protection functions, active energy balancing between modules, and automatic configuration detection after startup ("one-button commissioning") significantly simplify the deployment process. The BCU also features a built-in heater, enabling safe battery charging in low temperatures. IP66 protection and air cooling ensure stable and long-term operation in industrial environments, even with elevated environmental and operational requirements.
