1 SCOPE OF USE
The Fronius Sensor Box/Card collects data from connected sensors and communicates this data to the
Fronius Datamanager Box/Card via the Fronius Solar.Net communication loop.
It is not possible to retrieve data directly from the Fronius Sensor Box/Card without a Fronius Datamanager
Box/Card to manage communication.
2 HOW TO CONNECT A FRONIUS SENSOR BOX/CARD INTO A
FRONIUS SOLAR.NET LOOP
SnapINverters come equipped with 2 RJ45 sockets labelled IN and OUT. The Ethernet cable connection
should always run from the OUT socket on one inverter, to the IN socket on the next inverter or Fronius
Sensor Box/Card.
RJ45 termination plugs (supplied with the Fronius Datamanager) must then be installed in the empty Solar
Net IN and OUT connection sockets at the start and end of the daisy chain.
Up to 99 slave inverters and up to 10 Fronius Sensor Boxes/Cards can be connected to a master inverter.
To maximise communication speed, the number of devices and cable lengths should be kept to a minimum.
