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 inputs and outputs. RJ45 plug connectors are used to make the
connection.
IMPORTANT! Since the Fronius Datamanager functions as a data logger, the
Fronius Solar Net ring must not include any other data logger.
Only one Fronius Datamanager per Fronius Solar Net ring!
Any other Fronius Datamanagers must be removed and the unoccupied option
card compartment sealed off using the blanking cover (42,0405,2020 - available
from Fronius as an optional extra); alternatively, use an inverter without Fronius
Datamanager (light version).
Installing option
Information on installing option cards (e.g.: Datamanager) in the inverter and
cards in the in-
connecting the data communication cable can be found in the Installation In-
verter
structions.
Dynamic power
Energy companies or grid operators may impose feed-in limits on an inverter. Dy-

A counter for determining self-consumption of the S0 can be connected directly

Grid feed-in limit
Field for entering the maximum grid feed-in power in W. If this value is ex-
ceeded, the inverter regulates down to the set value within the time required
by national standards and regulations.
Pulses per kWh
Field for entering the pulses per kWh of the S0 meter.
