Device configuration

Components

All available components of the system can be added via
PV generator
Activate the MPP tracker and enter the connected PV output in the relevant
field. In the case of combined solar module strings, "PV 1 + PV 2 connected in
parallel" must be activated.
Primary meter
For problem-free operation with further energy generators and in Full Backup
power operation, it is important to install the Fronius Smart Meter at the feed-in-
point. The inverter and further producers must be connected to the public grid
via the Fronius Smart Meter.
This setting also has an effect on the behavior of the inverter during the night. If
the function is deactivated, the inverter switches into standby mode as soon as
there is no more PV power available. The message "Power low" is displayed. The
inverter starts again as soon as sufficient PV power is available.
If the function is activated, the inverter remains permanently connected to the
grid in order to draw energy from other producers at any time.
After connecting the meter, the position must be configured. An individual Mod-
bus address must be set for each Smart Meter.
The Watt value at the generator meter is the sum of all the generator meters.
The Watt value at the load meter is the sum of all the load meters.
Functions and Backup power
I/Os In backup power mode, it is possible to select between "Off" and "PV Point".
IMPORTANT!
The notes in the chapter headed
figuring the "PV Point" backup power mode.
Backup power nominal voltage
When backup power mode is activated, the nominal voltage of the public grid
must be selected.
Load management
Up to four pins for the load management can be selected here. Further settings
for the load management are available in the
Default: Pin 1

Inverter

"Force standby"
When this function is activated, the supply of energy from the inverter into the
grid is interrupted. This makes it possible to shut down the inverter without
power and protect its components. The standby function is automatically deac-
tivated when the inverter is restarted.
