one", as previously set in the commissioning
process. Then, it will re-enable the microgrid
for seven minutes. The essential loads and
the AC-coupled PV inverter will re-connect
consequently.
▶ If there is sufficient excess PV energy to charge
the battery, the microgrid will be maintained.
▶ Otherwise, the microgrid will be deactivated,
and the system will go to 'standby mode' again.
The essential loads and the AC-coupled PV
inverter will disconnect consequently.
▶ 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:
▶ Ensure the storage system is turned on prior to
using the blackstart button. Green power button
in ON position.
▶ Switch on the storage system using the green
power button.
▶ Press and hold the blackstart button for up to 5
minutes until the status LED illuminates.
If there is sufficient excess PV energy to charge
the battery, the microgrid will be maintained.
Otherwise, the microgrid will be disonnected,
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 electricity in the battery when
electricity prices are low, and then use this stored
electricity to supply the household appliances at
times of peak rate. The batteries are prevented
from discharging during the selected windows of
time of use.
If your electricity provider company offers you
time of use electricity tariffs, in which there is a
price difference between the peak and off-peak
rates, you may consider setting the storage system
to time of use mode.
