The Dyness STACK280 BDU & Base is the essential control and mounting foundation for building a complete Dyness STACK280 high-voltage (HV) battery stack. It combines the Battery Disconnect/Distribution Unit (BDU) with the base pedestal, providing the electrical control point, protection interface, and stable physical support required to assemble STACK280 modules into a safe, scalable ESS system.

Designed for professional installations, the BDU manages system start/stop and protection logic, enables communication between the STACK280 battery stack and the inverter/EMS, and supports reliable operation of the complete HV storage cluster. The base ensures correct alignment, airflow spacing, and a stable footprint for secure stacking—making installation cleaner, safer, and easier to service.

Key benefits

• Required component for STACK280 stacks: forms the foundation and control hub for STACK280 module assemblies

• BDU control + protection interface: central unit for safe system operation and fault handling

• Communication-ready integration: supports system communication to compatible inverter platforms (protocol-dependent)

• Stable mechanical base: correct positioning and a secure footprint for stacking modules

• Service-friendly system design: simplifies commissioning, maintenance and future expansion

Typical use

Use this item when building a Dyness STACK280 HV system: the BDU & Base is installed at the bottom of the stack, and the STACK280 battery modules are stacked above it to achieve the required voltage and capacity for the ESS project.

Important note: This product is intended for Dyness STACK280 high-voltage systems only and must be installed and commissioned by qualified professionals in accordance with local regulations.
