Step
Description
1
Open the screws on the service flat using a PH2 screwdriver.
2
Keep the switch-on button pressed for at least 10 seconds.
3
After approximately 8 seconds, both LEDs start flashing quickly (100 ms flash cycle).
Keep the button pressed for 2 more seconds.
4
The LEDs switch off. The battery storage system is now switched off.
A clicking sound must be heard.
Switch off the battery storage system using time
The battery switches off automatically after a defined time of 20 minutes when the battery does not detect
any CAN communication externally.
Step
Description
1
If an external source (e.g. the battery inverter) does not detect a CAN communication of the battery, the battery
switches off automatically after 20 minutes.
2
Optional:
If the battery is installed in
parallel mode
, the battery defined as master first switches off after 20 minutes
without CAN communication of the external source.
The slave battery then switches off after 20 minutes.
If a master or a slave battery is now switched on in the parallel mode, all batteries in the complete system are
switched on since they are activated by the pre-charging voltage of the battery that is switched on first (see
Switching on the battery storage system using an external voltage source

Configuring the parameters of the inverter
The inverter parameters must be configured for the BMZ ESS 7.0 battery in order to operate it optimally in
combination with the inverter.
See section 4.18
