Depending on the model, the inverter may be equipped with the Fronius Datamanager
plug-in card.
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 enables 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 communi-
cation between one or several inverters that are connected on the Fronius Solar Net us-
ing a system add-on.
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 as-
signed a unique number.
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.
More detailed information on the individual system add-ons can be found in the relevant
operating instructions or on the internet at www.fronius.com
