Operating mode
The ISS 1Play 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 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.
When photovoltaic energy is used to supply the loads or charge the batteries, there is a
o
reduction in grid consumption.
In the event of surplus photovoltaic energy, the user can decide whether to supply the grid or
o
limit photovoltaic production through the configuration.
If the grid is out of service, the ISS 1Play disconnects the installation from the grid and provides
energy to the loads from the batteries until they get discharged.
