3.3.2 Work modes
The AEG AS-BSL1-8000 / AS-BSL1-12000 energy
storage system works in the following modes:
Mode 1
- During daytime, the energy from the
photovoltaic plant is directed to charge the battery as
a priority. If / When the battery is fully charged, the PV
power will be used to power the loads, and the excess
power will be fed to the grid.
Mode 2
- During nighttime, the battery powers the
loads. If the energy in the battery is not sufficient, the
difference will be supplied by the grid.
Mode 3
- If the grid is subject to malfunction, or in
regions that are off-grid, the photovoltaic plant and the
battery can both concur to power the loads.
Mode 4
- When the battery is low and if power from the
photovoltaic plant is unavailable, the energy to charge
the battery and to power the loads will be supplied by
the grid.
Mode 5
- A generator can charge the battery bank.
.
Mode 6
- If the function „Time Of Use“ is on, it will
ensure that the power to charge the battery and the
power sold to the grid can be balanced.
Mode 7
- The UPS (Uninterrupted Power Supply)
Function can ensure that the main loads are still
powered even in case of sudden grid failure.
