The following drawings show the connection configurations when the Battery/Storage controller is using the DEIF Generic Modbus client protocol.
- ESS = Energy storage system
- BCU = Battery control unit
- BMS = Battery management system
- PCS = Power conversion system.
Connection to the BCU
Select DEIF Generic in ESS protocol (parameter 7561) and select OFF in BMS protocol (parameter 7682).
Connection to the BMS and PCS
Select DEIF Generic in ESS protocol (parameter 7561) to control the PCS and select DEIF Generic in BMS protocol (parameter 7682) to control the BMS.
You can choose different Modbus server IDs for the PCS and BMS control.
You can select another protocol for the PCS or BMS control. See DEIF Hybrid controller compatibility for more information.
