Energy management
Energy manage-
ment Self-consumption optimisation
The inverter always adjusts to the set target value on the Smart Meter. 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 Smart Meter.
However, in this case:
- The Fronius Smart Meter must be installed at the feed-in point
- Battery charging must be activated by another producer
The self-consumption optimisation has lower priority than the battery control
specifications.
Self-consumption optimization
Switch self-consumption optimization to automatic or manual.
Target value on Smart Meter
If a manual selection is made under self-consumption optimisation, the target
value on the Smart Meter and the reference/feed-in can be selected here.
External producers (only possible with active battery and inverter with battery
connection)
If further decentralised producers are installed in the house, and these are incor-
porated into the self-consumption regulation of the Fronius Hybrid inverter, this
setting must be activated. This means that energy can be drawn from the house-
hold network and fed into the battery via the Fronius GEN24 inverter. You can re-
strict how much power is consumed by the Fronius GEN24 inverter by specifying
the maximum AC power (AC max.). A maximum power consumption of the AC
rated power of the Fronius GEN24 inverter is possible.
PV power reduc-
tion The battery control specifications make the generated energy as optimally us-
able as possible. Situations may arise, however, in which PV energy cannot be
used in full due to battery control specifications.
Example
Fronius inverter 6000 W (max. output power)
BYD Battery-Box Premium HVS / HVM
defined discharge 6000 W
PV power 1000 W
In this case, the inverter would have to reduce the PV power to 0 W, since the
output power of the inverter is max. 6000 W and the device is already being used
to capacity by the discharging.
Since it doesn't make sense to waste PV power, the power limit is automatically
adjusted in the battery control specifications such that no PV power is wasted. In
the example above, this means that the battery is discharged only at 5000 W, so
that the 1000 W PV power can be used.
