Sources and notes

Source: Fronius, "Fronius Datamanager Modbus TCP & RTU" (42,0410,2049, 033-24022026) and "Modbus SunSpec Maps, State Codes and Events" (archive 1.1.7); https://www.fronius.com/~/downloads/Solar%20Energy/Operating%20Instructions/42,0410,2049.pdf

  • Fronius inverters with the Datamanager 2.0, read through SunSpec models (float meter models 211-213).
  • Addresses are the register numbers printed in the manual (1-based): the first register, 40001, is sent on the wire as 40000.
  • Register positions after the inverter model change with the SunSpec model type (float or integer with scale factors), selected in the Datamanager web interface or in register 216.
  • A value the device cannot provide is returned as the unavailable value of its type (see sentinels).
  • A Fronius Smart Meter on the Datamanager is read with Modbus device ID 240 (240 to 244 for several meters).
