Dyness STACK100 BDU & Base
The controller and standard base for the Dyness STACK100 high-voltage battery system. The SBDU100 connects a compatible STACK100 battery stack to its inverter and manages system control, communication and monitoring. Battery modules and inverter are sold separately.
Key Features
- Essential system controller: The SBDU100 manages the STACK100 battery stack and provides the power and communication interfaces to a compatible high-voltage inverter.
- Matched controller and base: One BDU and one standard base form the control and support components for a STACK100 stack of 3–15 battery modules.
- Integrated control and protection: Power-on and wake controls, LED status indicators and a DC circuit breaker with short-circuit protection.
- Inverter communication: CAN and RS485 communication ports, together with dedicated parallel communication connections for multiple clusters.
- Connected monitoring: WiFi and Dyness app support system monitoring and OTA updates.
Where to Use
Indoor residential and commercial solar energy storage systems using the standard Dyness STACK100 range and an approved high-voltage inverter. A complete battery stack can support solar self-consumption, load shifting and backup applications where supported by the inverter and system design.

Additional Details
- What this listing supplies: One Dyness STACK100 BDU and one standard base. The STACK100 S51100 battery modules and inverter are sold separately.
- Configuration: A standard single-column STACK100 stack requires 3–15 compatible S51100 modules. Select the module count to suit the inverter’s approved battery voltage window.
- Installation accessories: Refer to the manufacturer’s packing list for fixings, termination and communication accessories. Battery-to-inverter power cables are listed as optional in the manual and must be selected for the complete system.
- Expansion layouts: Split-column layouts require the appropriate STACK100 extension components and the manufacturer’s base-conversion procedure. This standard base is supplied for the standard single-column configuration.
