Fronius Energy Package, Operating Instructions Manual, Page: 33 / 148

In Fronius Solar.web or on the web interface of the inverter,
the calibration charge information is displayed in the over-
view. Clicking on the battery symbol (see the image on the
left) displays the information "The battery is in calibration
mode"
In the energy balance display in Solar.web, both the start and end of the calibra-
tion charge is displayed by changing the battery status ("Battery Mode: Normal
→
Calibrate" and "Battery Mode: Calibrate
→
Normal")
The following graphic shows calibration charging of the Fronius Solar Battery in
the energy balance view. At the start of calibration charging, the total PV pro-
duction is used to charge the battery. From the point where one cell is fully
charged, only a certain charging current is drawn by the battery. This charging
current decreases towards 0 A as the cell voltage increases.
As during normal operation, the status "charging" (CHG) is shown on the battery
display and the relevant charging current in ampere is displayed. If the charging
current drops to below 0.3 A, 0 A is shown on the display, even though calibration
charging continues.
In Fronius Solar.web, the SOC value for the entire battery is displayed. On the
battery display, the SOC values of the individual battery modules can be viewed.
