Data communication and Fronius Solar Net
Fronius Solar
Net and data in-
terface
Fronius Solar Net was developed to make system add-ons flexible to use in a
variety of different applications. Fronius Solar Net is a data network that en-
ables multiple inverters to be linked up using system add-ons.
It is a bus system that uses a ring topology. One suitable cable is sufficient for
communication between one or several inverters that are connected on the
Fronius Solar Net using a system add-on.
Similarly, every inverter on the Fronius Solar Net must be assigned a unique
number.
Refer to the section entitled "The SETUP menu item" for instructions on how
to assign a unique number.
Fronius Solar Net automatically recognises a wide variety of system add-ons.
In order to distinguish between several identical system add-ons, each one
must be assigned a unique number.
More detailed information on the individual system add-ons can be found in
the relevant operating instructions or on the internet at http://www.froni-
