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 (max-
imum 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
- It is necessary to activate battery charging by a further producer (see chapter (→
TARGET NOT FOUND) on page (→ TARGET NOT FOUND) ).
The self-consumption optimisation has lower priority than the battery control specifica-
tions.
Self-consumption optimisation
Switch to self-consumption optimisation automatically or manually.
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
If further decentralised producers are installed in the home, and these are incorporated
into the self-consumption regulation of the Fronius Hybrid inverter, this setting must be
activated. This means that energy can be drawn from the household network and fed
into the battery via the Fronius GEN24 Plus inverter. You can restrict how much power is
consumed by the Fronius GEN24 Plus inverter by specifying the maximum AC power
(AC max.). A maximum power consumption of the AC nominal capacity of the Fronius
GEN24 Plus inverter is possible.
Battery control specification:
Using the time-dependent battery control, it is possible to prevent or restrict the charging/
discharging and to specify a defined value for charging/discharging.
The battery is influenced by external factors, e.g. calibration charging, charging from AC
permitted, power limit of the inverter, control specifications via Modbus, or self-consump-
tion optimisation. The battery control specifications have the second lowest priority, fol-
lowing the self-consumption optimization, and it may be the case that these are not ful-
filled due to other specifications.
Without any battery control specifications, optimization is performed to the best possible
self-consumption. Self-consumption decreases when battery control specifications are
defined.
The following values can be selected in the column "regulation":
-
max charging power
The battery is charged with the power set in the field "power" at most
- min charging power
The battery is charged with the power set in the field "power" at least
- max discharging power
The battery is discharged with the power set in the field "power" at most
- min discharging power
The battery is discharged with the power set in the field "power" at least
The day and time window in which this regulation applies is defined in the columns "Day
of the week" and "Time window". It is not possible to define a time window over midnight.
