Commissioning the parallel connection of multiple batteries
4.14.1 Switch-on sequence
1. At the time of commissioning , first switch on the master battery .
2. Check whether the main relay of the master battery is switched on
-> Check via LED flashing speed (see section 5.1) or BMZ service tool (see section 4.4)
3. If the main relay of the master battery is closed, you can now switch on other slave batteries.
4.14.2 Stand-by mode of a slave battery:
When you switch on the slave batteries, the batteries are automatically in the stand-by mode. (The stand-by
mode is indicated by a green flashing LED) Only when the master sends a switching signal for the main relay
of the slave battery, the main relay of the slave battery is switched on. The slave battery can be used the
complete battery system only after this.
4.14.3 Switch-on criterion of the slave battery:
Each battery compares the internal battery voltage with the externally applied voltage through a
measurement.
Figure 4-33: block circuit diagram of the BMZ ESS slave battery
If the voltage automatically measured by the battery at the master battery differs from the slave battery
voltage by less than +/-100 mV, the slave battery switches off automatically.
