Data Communication and Solar Net

Solar Net and
Fronius developed Solar Net to make these add-on system components flexible and ca-
data interface
pable of being used in a wide variety of different applications. Solar Net is a data network
that enables several inverters to be linked with the data communications components.
Solar Net is a bus system. A single cable is all that is required for one or more inverters
to communicate with all system upgrade components.
The core of the Solar Net is the Fronius Datalogger. It coordinates data transmissions and
ensures that even large volumes of data are distributed quickly and securely.
The 'Fronius Com Card' is used to integrate the inverter into Solar Net.
Important Every inverter that is to be monitored using a Datalogger requires a 'Fronius
Com Card.' In this case, the 'Fronius Com Card' serves as a link between the internal net-
work of the inverter and the Solar Net interface of the Datalogger.
Important Each inverter can have only one 'Fronius Com Card.' A network may only con-
tain one Fronius Datalogger.
The first inverter with a 'Fronius Com Card' can be positioned up to 3280 ft. (1000 m)
away from the last inverter with a 'Fronius Com Card.'
Different system upgrades are detected automatically by Solar Net.
In order to distinguish among several identical system upgrades, each one must be as-
signed a unique number.
In order to uniquely identify each inverter in Solar Net, each inverter must also be as-
signed an individual number.
You can assign individual numbers as per 'The setup menu' section in this manual.
More detailed information on the individual data communications components can be
found in the relevant operating instructions or on the Internet at http:\\www.fronius-
