Example
Recording and archiving data from the inverter and sensor using a Fronius Datamanager
and a Fronius Sensor Box:
Data network with 3 inverters and a Fronius Sensor Box:
- Inverter 1 with Fronius Datamanager
- Inverters 2 and 3 without Fronius Datamanager!
The external communication (Fronius Solar Net) takes place on the inverter via the data
communication area. The data communication area contains two RS 422 interfaces as in-
puts and outputs. RJ45 plug connectors are used to make the connection.
IMPORTANT! Since the Fronius Datamanager functions as a data logger, the Fronius So-
lar Net ring must not include any other data logger.
Only one Fronius Datamanager per Fronius Solar Net ring!
