Dyness Stack 280 BDU Single Unit

The Dyness Stack 280 BDU & Base is the control and distribution unit for the Stack 280 modular battery system. It manages battery distribution, protection and communication for the cluster, supporting 3 to 15 Stack 280 modules (43-215.04kWh) per BDU, with up to 12 clusters paralleled for a maximum system size of approximately 2.58MWh. The BDU communicates via CAN or RS485 and includes WiFi for remote monitoring and OTA updates. It also controls the cluster’s aerosol fire-suppression system, activating within seconds if a fire risk is detected. One BDU is required per Stack 280 cluster; battery modules are sold separately.
