Dyness BDU100 HV Battery Control Unit Overview
The Dyness BDU100 HV Battery Control Unit is the intelligent battery management and control module designed specifically for the Dyness Stack100 high-voltage lithium battery system. This unit acts as the central communication and protection interface between the Stack100 battery modules and compatible hybrid inverters.
The BDU100 is an essential component required for the operation of Dyness S51100 high-voltage battery modules and forms the foundation of the complete Stack100 energy storage platform.
What Does the Dyness BDU100 Do?
The BDU100 functions as the main battery control and communication unit for the Dyness Stack100 system. It manages communication between the battery modules and inverter while monitoring voltage, current, temperature, charging, discharging, and system safety.
Without the BDU100 control unit, the Dyness Stack100 battery modules cannot operate correctly as a complete high-voltage battery system.
