Energy manage-
ment Own consumption optimization
The Fronius hybrid inverter always controls the system by adjusting it in line with
the target value set at the metering point. In the "automatic" operating mode
(factory setting), an adjustment is made to 0 W at the feed-in point (maximum
self-consumption).
The target value also applies if a further source feeds into this metering point.
However, in this case:
- The Fronius Smart Meter must be installed at the feed-in point
- It is necessary to activate battery charging by a further producer (see
chapter
Battery management on page 106 )
The self-consumption optimisation has lower priority than the battery control
specifications.
Own consumption optimization
Option for selecting automatic or manual self-consumption optimisation
Target value at the metering point
If you opt for "manual" under "Own consumption optimization", you can select
the target value at the metering point and choose between "Consumption" and
"Feed-in" here
Backup power
Operating mode
"Automatic" or "Off" can be selected for backup power mode.
The backup power functionality can only be activated once the required IO as-
signments have been configured for backup power. The meter must be installed
at the feed-in point and configured.
Residual battery capacity
Energy is drawn from the battery in grid-connected operation until this residual
battery capacity is reached. In backup power mode without a grid, the battery is
always discharged to the minimum SOC preset by the battery manufacturer.
SOC warning level
A warning is output when the residual capacity of the battery specified here is
reached in backup power mode.
Energy manage-
ment examples These examples illustrate possible energy flows. Efficiency values have not been
taken into account.
