SETTING UP A FRONIUS SOLAR INVERTER

The values from a Fronius Inverter can be read using Fronius’s RS232 Converter Box and Loxone’s RS232 Extension.

SELECT THE PROTOCOL

Connection Parameters:
Auto-baud rate (2400, 4800, 9600, 14400, 19200), 8 data bits, 1 stop bit.
In order for the sensor values to be transmitted, you must select the ‘Fronius’ protocol.

CHANGE ID IN THE SETUP MENU

The inverter responds only to a value-request. These requests are saved in the actuators, therefore a pulse at the actuator writes the current value to the corresponding sensor.
In this request-command the inverter’s ID is included (which can be changed in the setup menu). By default, a request-command saves the ID 01.
