Switch on the battery storage system using an external voltage source
Proceed as follows to start the battery storage system:
Step Description
1
The external voltage source can be used to switch on the system only if it was not switched off using the push
button (press the push button longer than 10 seconds at a stretch).
2
Connect an external voltage source greater than 36 VDC.
3
The battery detects the external voltage source automatically and switches the operating mode from inactive to
active.
4
If it is switched on in an unauthorised manner, the green LED flashes quickly (100 ms flash cycle)
You must now start the battery using a normal switch-on sequence (by pressing the push button longer than 1
second).
Switch off the battery storage system using a push button
Proceed as follows to switch off the battery storage system:
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.
4.5.3 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.
