From the manufacturer manual
- Solar inverters Datamanager SunSpec inverter (float) Modbus map of a Fronius inverter read through the Fronius Datamanager over Modbus TCP or Modbus RTU. It holds the SunSpec common block, inverter model 111/112/113 (float setting), nameplate, basic settings, extended measurements, immediate controls, multiple MPPT and basic storage control models, plus the Fronius specific registers and site totals. Fronius meters on the same Datamanager use a separate map. The tables are the float setting; the integer with scale factor setting uses models 101 to 103 and different addresses.
- Energy meters Smart Meter SunSpec (float) Modbus map for an energy meter (for example a Fronius Smart Meter) connected to a Fronius Datamanager over Modbus RTU and read over Modbus TCP as SunSpec meter model 211/212/213 (float setting). It lists the common block, AC currents, voltages, power, frequency, power factor and total energy counters. Registers marked not supported in the vendor table are omitted.
