If the battery was not fully charged at this time, it is
imperative to fully charge it to synchronize the display
with the battery level.

- Name 2/3:
4.3.1 Designation
This name is displayed in the battery symbol of the display and is used for easier assignment.
4.3.2 Nominal capacity
The rated capacity of the battery (1-9999 Ah) is set here. To obtain a reasonable accuracy of the
remaining time function as well as the percentage charge display, the capacity of the battery to be
monitored must be set.
Please note that the capacity of the battery should only be adjusted when the batteries are 100%
charged, as this will set the capacity indicator to 100% and all internal counters to 0.
If the battery was not fully charged at this time, it is imperative to synchronize the display with the
battery state of charge.
4.3.3 Rated voltage
Please set the rated voltage 12 or 24V of the battery group so that the capacity calculation can be
performed properly.
4.3.4 Battery type
To adjust the "Battery Low" and "Battery Full" detection, the type of battery used [GEL, ACID,
AGM, Lithium] must be entered.
4.3.5 Ah efficiency (CEF)
Each battery has an Ah efficiency. This means that more amp hours must be loaded into the battery
than can be taken. The efficiencies of lead batteries are between 80% and 95%. If the CEF
deteriorates below 70% during operation, this basically means that the battery has reached the end
