Battery manage-
ment Battery charging/discharging limits:
The battery charging / discharging limits can be set "automatically" or "manu-
ally".
If they are set automatically, suitable values are selected for the battery.
If they are set manually, values can be set in the "Max SoC" (maximum state of
charge) and "Min SoC" (minimum state of charge) fields. The range of values that
can be set differs depending on the battery. In backup power mode without a
grid, the set values are not taken into account.
IMPORTANT! The settings must be agreed with the battery manufacturer! Froni-
us accepts no liability for damage to third-party batteries.
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 affected by external factors, such as calibration charging, permit-
ting AC charging, inverter power limitation, control parameters via Modbus or
self-consumption optimisation. The battery control specifications have the
second lowest priority, following the self-consumption optimization, and it may
be the case that these are not fulfilled due to other specifications.
Without any battery control specifications, optimization is performed to estab-
lish the best possible degree of 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 at no more than the power set in the field "power"
- min charging power
The battery is charged at no less than the power set in the field "power"
- max discharging power
The battery is discharged at no more than the power set in the field "power"
- min discharging power
The battery is discharged at no less than the power set in the field "power"
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.
Example: Two entries are needed to set a parameter of 22:00 to 06:00: '22:00 -
24:00' and '00:00 - 06:00'.
Examples for the battery control specifications can be found in the following
chapter.
Calibration charging (only for Fronius Solar Battery)
At regular intervals, the Fronius hybrid inverter automatically charges the Froni-
us Solar Battery until it is full for the purpose of calibrating all the components.
This process can be started manually here.
IMPORTANT! When calibration charging is activated, normal operation is inter-
rupted and the system may draw energy from the distribution network operator's
grid. The process can take several hours and cannot be aborted.
Once calibration is complete, the system automatically reverts to the operating
mode that was set originally.
This calibration charging process is also performed automatically during actual
operation after a number of charging and discharging cycles.
If the "permit battery charging from DNO grid" setting is deactivated, this calib-
ration charging process relies exclusively on energy from the photovoltaic sys-
