Fronius developed Solar Net to make these add-on system components
flexible and capable of being used in a wide variety of different
applications. Solar Net is a data network which enables several Fronius
IG Plus units to be linked with the system upgrades.
Solar Net is a bus system. A single wire is all that is required for one or
more Fronius IG Plus units to communicate with all system upgrade
components.
The core of the Solar Net is the Datalogger. It coordinates data
transmission and ensures quick and safe distribution and storage of large
volumes of data.
The ‘Fronius Com Card’ is required to integrate the Fronius IG Plus into
the Solar Net.
Important Every Fronius IG Plus that is to be monitored using a Data-
logger requires a ‘Fronius Com Card.’ In this case, the ‘Fronius Com Card’
serves as a link between the internal network of the Fronius IG Plus and
the Solar Net interface of the Datalogger.
Important Each inverter can only have one ‘Fronius Com Card.’ A net-
work may only contain one Datalogger.
The first Fronius IG Plus with a ‘Fronius Com Card’ can be up to 3280 ft
(1000 m) away from the last Fronius IG Plus with a ‘fronius Com Card’.
Different system upgrades are detected automatically by Solar Net.
In order to distinguish between several identical system upgrades, each
one must be assigned a unique number.
