    • debugLog

      public String debugLog()
      Description copied from interface: OpenemsComponent
      Gets some output that is suitable for a continuous Debug log. Returns 'null' by default which causes no output.
      Specified by:

      the debug log output
    • getModbusSlaveTable

      public ModbusSlaveTable getModbusSlaveTable(AccessMode accessMode)
      Description copied from interface: ModbusSlave
      Gets the Modbus-Slave-Table for this OpenEMS-Component.
      Specified by:
      getModbusSlaveTable in interface ModbusSlave
      accessMode - filters the Modbus-Records that should be shown

    • setStartStop

      public void setStartStop(StartStop value)
      Description copied from interface: StartStoppable
      Starts or stops the device or service represented by this OpenEMS Component.
      Specified by:
      setStartStop in interface StartStoppable
      value - target StartStop state
    • getStartStopTarget

      public StartStop getStartStopTarget()
      Description copied from interface: BatteryFeneconHome
      Gets the target Start/Stop mode from config or StartStop-Channel.
      Specified by:
      getStartStopTarget in interface BatteryFeneconHome
    • updateNumberOfTowersAndModules

      protected void updateNumberOfTowersAndModules()
      Update Number of towers and modules; called on onChange event.

      Recalculate the number of towers and modules. Unfortunately the battery may report too small wrong values in the beginning, so we need to recalculate on every change.

      As an alternative, these channels may also be introduced in a record, and the associated channel value could be read with the aid of ChannelUtils.getValues(io.openems.edge.common.component.OpenemsComponent, java.lang.Class<T>). However, startup time is once again involved in this process. This indicates that the last callback will have been made before the record is set. Furthermore, there is no certainty that the "software version channel value change" will occur, making it unlikely for this to trigger a callback.

    • buildSerialNumber

      protected static String buildSerialNumber(String prefix, Integer value)
      Build the serial number with prefix.
      prefix - the serial number prefix
      value - the serial number
      The serial number
