Dyness SBDU100 STACK100 High-Voltage Battery Controller & Floor Base
Exact reference · SBDU100
The protection, communication and high-voltage connection layer for a Dyness STACK100 cluster, supplied with one standard floor base.
- Product role
- Battery distribution / control unit
The SBDU100 contains no cells and contributes no energy capacity.
- Operating range
- 134.4–864 V
The actual cluster voltage depends on the selected 3–15-module stack and inverter window.
- Continuous current
- 100 A maximum
The recommended complete-stack operating current is 50 A; conductors and protection must suit the commissioned design.
- Included package
- SBDU100 + standard floor base
No S51100 battery module is included.
- Installation boundary
- IP20 · indoor
Use a suitable indoor location with documented support, restraint, clearances and environmental conditions.
Do not select this controller from voltage range or STACK100 branding alone. Confirm module count, inverter protocol, firmware, cluster voltage, current, standard-versus-expansion base, indoor installation and commissioning records.

01 · Product role
What this product does in the system.
The SBDU100 sits above three to fifteen separately ordered S51100 modules and provides the cluster high-voltage connection, integrated DC breaker, status indication and inverter communications. The supplied standard floor base is physical mounting and circuit-connection equipment for one cluster; it is not a battery module.
Relevant applications
- Indoor commercial high-voltage storage systems
- Single STACK100 clusters using 3–15 S51100 modules
- Multi-cluster projects using the documented expansion-base and communication architecture
Why ReneWave may shortlist it
- Provides the STACK100 cluster DC breaker, power controls and status indicators.
- Communicates with a separately validated inverter through CAN or RS485.
- Includes the standard floor base required for a single-cluster installation.
Built-in capabilities
Four functions, read before the headline specifications.
Provides fault protection
Includes the documented DC breaker, power controls and status indicators.
The SBDU maximum continuous-current boundary is 100 A.
Coordinates communications
Provides CAN and RS485 inverter links with WiFi and app OTA support.
Protocol, firmware, cable and pinout remain inverter-specific.
Coordinates 3–15 modules
One SBDU100 manages a documented S51100 module stack.
Multi-cluster expansion requires separate expansion-base equipment and commissioning.
System position
Where this controller sits in a STACK100 storage system.
The SBDU100 connects separate S51100 modules to a compatible high-voltage inverter. It contains no cells, performs no AC conversion and cannot supply loads by itself. Physical package: one standard STACK100 floor base is included. It supports a single cluster and is not an electrical-flow node.
PV supplies protected site loads through the compatible inverter. The STACK100 cluster remains idle.
Read the technical explanation
The protection, communication and high-voltage connection layer for a Dyness STACK100 cluster.
The supplied package contains one SBDU100 battery distribution/control unit and one standard STACK100 floor base. It contains no battery cells or energy capacity. A working cluster requires three to fifteen separately ordered S51100 modules and a validated high-voltage inverter/charger.
Base and expansion boundary
The standard base supports one cluster. Multi-cluster expansion requires the documented expansion-base conversion, communication and commissioning architecture; it is not an arbitrary parallel connection.
