Description

The Dyness SBDU100 BMS control module is a key element of an energy storage system, responsible for the smart management of battery modules and for optimising the operation of the entire power system. It is purpose-built to work with the Dyness S51100 51.2V 100Ah battery series and performs the mission-critical functions of monitoring, balancing, protection and communication. In effect, it is the “brain” of the system, ensuring its stability, efficiency and safety.

The module continuously tracks the key operating parameters of the batteries:

  • voltage
  • current
  • temperature
  • state of charge

The built-in BMS provides comprehensive protection against:

  • overcharging
  • deep discharge
  • short circuit
  • overload
  • overheating

Automatic cell balancing prevents uneven wear and keeps battery capacity at a high level throughout the entire service life.

The Dyness SBDU100 BMS supports the CAN and RS485 interfaces, which makes it easy to integrate with a wide range of inverters and control systems.

This opens up options for:

  • connection to residential and commercial solar plants
  • integration into industrial power systems
  • remote monitoring and control

The user gets access to full analytics on system operation and can react promptly to any changes.

The BMS implements multi-level safety at every stage of operation. If critical conditions arise, the module:

  • automatically disconnects the batteries
  • switches the system to a safe mode

Built-in indicators let you quickly assess the state of the system — charge level, activity and the presence of faults. This is especially important for large-scale energy solutions where stability is the priority.

The module’s design is engineered for maximum installation convenience:

  • compact form factor
  • integration on a plug-and-play
  • minimal maintenance requirements

Thanks to its functionality, reliability and ease of integration, this is the ideal choice for modern energy solutions based on S51100 batteries.
