Important:
To ensure that all slave batteries are activated from the master battery in case of a different voltage level
for different batteries, change the charge status of the master battery by charging and discharging using the
inverter.
Within a full cycle (i.e. the battery is completely charged once and completely discharged once), the master
battery scans all slave batteries in the stand-by mode and switches them off one by one.
This process may take a few hours depending on the available PV energy or loads in the company network.
4.14.4 Example 1:
6 batteries connected in parallel with different charge statuses:
- The master battery is switched on and the main relay is switched on
- 2 slave batteries are switched on and the main relay is switched on
- 3 slave batteries are switched on and the main relay is NOT switched on

4.14.5 Example 2:
6 batteries connected in parallel with different charge statuses:
- The master battery is switched on and the main relay is switched on
- 4 slave batteries are switched on and the main relay is switched on
- 1 slave battery is switched on and the main relay is NOT switched on
