Hi,
I would like to purchase your charging station with a smart meter, and I already have a solar power system. I couldn’t find in the instructions—either explicitly or because I don’t fully understand—whether the charging station allows switching from three-phase charging to single-phase charging (when one of the three phases runs out of available current up to the maximum limit, e.g., 25A per phase) and then switching back to three-phase charging when the load on the remaining phases decreases.
If this functionality is available, I would like to know when this switching occurs and whether it is possible to configure or modify these conditions. In which charging modes does this automatic switching between three-phase and single-phase charging (and vice versa) work?
I am particularly interested in this functionality during winter and at night when there is no solar energy production, as I have a single-phase heat pump and other high-power electrical consumers. It often happens that one or even two phases are heavily loaded with consumers, while the third phase might not be. If I understand correctly, your charger should be able to automatically select the “free” phase and use it for single-phase charging.
I believe that in the case where one or two phases are occupied, it is better for the charger to continue charging on a single phase rather than stopping the charging process entirely. That way, the vehicle can still be charged during this time instead of not charging at all.
thx
Bost
