Operating mode
The EMS of the ISS 1Play TL M manages the energy flows in the installation in line with the following
principles:
•
If the grid is available, it operates in the same manner as a self-consumption installation:
o
Photovoltaic energy is used as a priority to supply loads and to charge the battery. Grid
supply of photovoltaic surplus is user configurable.
o
If the photovoltaic energy is insufficient to power loads, the battery provides the remainder.
o
If the sum of photovoltaic and battery energy is not enough to power the loads, the grid
provides the remaining power.
o
Once the SOC Min value set by the user has been reached, the energy supply from the
battery is not restarted until SOC Recovery is reached. This prevents excessive battery
cycling, extending their working life.
o
The schedule for battery charging from the grid is user configurable.
•
If the grid is not operational and the Battery-Backup function is activated, only the ISS 1Play TL M
powers the critical loads until the battery is completely flat (SOC Descx). At this point, the critical loads
are no longer powered until the grid is available once again of until SOC Recx is reached using
photovoltaic energy of the ISS 1Play TL M. The INGECON SUN photovoltaic inverter is disconnected
to the grid and it doesn't supply energy.
