Fronius Interface The Fronius interface protocol is an open data protocol used to read photovoltaic system
Protocol measurement data from the inverter and process it further as required. The measurement
data are read using command inputs.
In addition to this, the output power can be specified in certain inverters with the interface
protocol.
Command inputs are made via a third party device (PC, etc.)
The data exchange is carried out via a serial interface:
