The loads are prioritized in the following order: PV system, energy storage system (GES), and then the grid. This prioritization ensures that renewable energy sources are utilized first, followed by stored energy and, if necessary, energy from the grid. Indeed, when there is an excess of PV production, the GES system is fully charged.
