Solar charging mode
Charging with this mode means that all power that would otherwise be injected into the grid is sent to the EV charger.
As a result, this mode cannot guarantee that charging will take place since one does not know in advance exactly how much ‘surplus’ there is.
If the solar production is lower than what the building consumes, charging will not take place.
When there is less than 6A ( ~ 1,350 watts for single-phase chargers, 4,000 watts for 3-phase systems) of PV surplus, the EV charger will automatically stop because the minimum charging current for electric cars is then no longer met. This situation can be seen in the figure above.
