Modbus binding with Sunny Boy SMA inverter

[alaub81 (Andreas)]

thanks for the answer I calculated it in that way:

  val Number TotalPower = (inverter1ActivePower.state as DecimalType
    + inverter2PreBatDischarge.state as DecimalType
    + inverter1PowerDrawn.state as DecimalType
    - inverter2PreBatCharge.state as DecimalType
    - inverter1PowerGridFeedIn.state as DecimalType)
  if ( TotalPower >= 0 ) {
    TotalPowerConsumption.postUpdate(TotalPower)
  }

But I will try your solution, too
