I notice that the delivery back to and the consumption from the GRID is done in a somewhat balanced way (depending on AC loads and others) having a 3phase GRID connection)
As in the Netherlands congestion and high voltage (253V) is getting more and more an issue i have the following suggestion:
Could the delivery back be done in a way that the phase with the lowest voltage is maximized?
And for consumption from GRID the other way around, so maximize consumption to phase with highest voltage?
