Dyness SBDU200 S51280/S51314 (Stackable Control Box)

The Dyness S51280/S51314 BDU200 (Battery Distribution Unit 200) is the central management and distribution controller for the Dyness STACK280/STACK314 high-voltage modular battery system. It connects and manages multiple S51280 battery modules wired in series, enabling a scalable HV architecture spanning 153.6V up to 768V — making it the essential control component for high-power commercial and large residential solar storage applications using compatible HV inverters.

The BDU200 is a required component of every STACK280/STACK34 installation. It must be paired with S51280/S51314 HV Battery modules to form a complete, operational system. The BDU200 does not store energy on its own.

High-Voltage System Controller (134–864V)

• Operating Voltage Range: Supports a wide HV operating range of 134V to 864V — providing compatibility across all STACK280/STACK314 module configurations, from a 3-module starter system at 153.6V through to a full 15-module array at 768V.

200A Continuous Output

• Current Rating: Rated at 200A continuous output, delivering the high power throughput required by HV-compatible inverters in commercial and large residential solar energy installations.

Series-Stack Architecture Management

• Configuration: Manages S51280/STACK314 battery modules connected in series (3 to 15 modules), creating a scalable high-voltage DC bus from 153.6V to 768V. This architecture is designed for compatibility with high-voltage inverter platforms requiring a HV battery input.

Centralised Protection & Communication

• System Function: Provides system-level protection, state-of-charge management, cell balancing oversight, and inverter communication for all connected S51280/S51314 modules — simplifying management of large-scale HV battery systems from a single, centralised control unit.

Required for All STACK280 Systems

• Note: One BDU200 is required per STACK280/STACK314 system. The BDU200 must be paired with compatible S51280/S51314 HV Battery modules. Confirm your complete system configuration, HV cabling requirements, and HV inverter compatibility with a qualified installer before ordering.
