Operating mode
The ISS 1Play TL M manages the energy flows in the installation in line with the following principles:
•
When the grid is operational, the priority is to keep the batteries fully charged SOC Grid so that they
can be used as back-up when required. Loads and the battery, if it must be charged, are supplied with
photovoltaic energy as a priority.
o
When photovoltaic energy is used to supply the loads or charge the batteries, there is a
reduction in grid consumption.
o
In the event of surplus photovoltaic energy, the user can decide whether to supply the grid or
limit photovoltaic production through the configuration.
•
If the grid is out of service, the ISS 1Play TL M disconnects the installation from the grid and provides
energy to the loads from the batteries until they get discharged SOC Descx. At this point, the 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.
