re-enable the micro-grid. The essential loads and the AC-coupled PV inverter will
re-connect consequently.
3.
If there is sufficient excess PV energy to charge the battery, the micro-grid will be
maintained.
4.
Otherwise, the micro-grid will be deactivated, and the system will go to ‘standby
mode’ again. The essential loads and the AC-coupled PV inverter will disconnect
consequently.
5.
The system will repeat steps 2 to 4 according to the “Reenabling time two” and
“Reenabling time three”, as previously set in the commissioning process. The
system will shutdown after the third attempt to prevent further battery discharge.
Blackstart Functionality
In case of a grid-outage the storage system will automatically enable and switch-over to
microgrid operation depending on the state-of-charge of the batteries. Alternatively, the
system operator has the ability to manually switch on the storage system without the grid
being present by using the blackstart button. In the process, the storage system will also
activate the microgrid.
For correct operation, please follow the steps below:
1.
Ensure the storage system is turned on prior to using the blackstart button. Green
power button in ON position.
2.
Switch on the storage system using the green power button.
3.
Press and hold the blackstart button for about 60 seconds.
If there is sufficient
excess PV energy
to charge the battery, the micro-grid will be
maintained.
Otherwise, the micro-grid will be disconnected, and the system will go to ‘standby mode’
again. The essential loads and the AC-coupled PV inverter will disconnect consequently.

Time-of-Use mode
This mode is similar in function to self-consumption except that the storage system will
charge the batteries from the grid during the specific time windows selected by the
customer. By setting the storage system to time of use mode, customers can store
