The Dyness Stack 100 BDU & Base (SBDU100) serves as the intelligent control center of your high-voltage (HV) energy storage system. This combination of Battery Distribution Unit and reinforced stack base platform ensures safe integration, communication management and performance control for 3 to 15 Stack 100 battery modules per tower. With integrated WiFi monitoring, active cooling and 1C support (100A), the BDU guarantees reliable high-power operation in demanding HV installations.

  • Central System Control: Manages 3–15 modules per tower (up to 76.8kWh).
  • Base Included: Heavy-duty foundation for secure stack mounting.
  • Integrated WiFi: Cloud monitoring & OTA firmware updates.
  • 1C High Power Support: 100A continuous, 125A peak (2 min @ 25°C).

Intelligent High-Voltage Energy Management

The smart BMS architecture continuously supervises voltage, current and temperature across connected modules. In case of overload, short circuit or abnormal thermal conditions, automatic protection protocols are activated. Integrated forced air cooling maintains stable performance during sustained high-load (1C-rate) operation in HV system configurations.

Installation requirement:
  • This product includes both the SBDU100 controller and the Stack 100 Base.
  • For parallel systems: ensure all towers are at 100% SOC and voltage deviation is <20V before connection.
  • HV installation must be performed by qualified professionals only.
