Difference between phases
From Wiki
Phase difference based on your grid. It can be 120° or 180°.
120° - Star (Wye) and Delta; 180° - Delta and split phase.
In the case of Europe, most Star (Wye) and Delta connections will have a phase difference of 120°. In North America, the phase shift can be 180° when split phase connection type is used or in the case of Delta connection with center tap on one leg.
Note: these parameters are used only for the power consumption (kWh) calculations and not influence operation of the charger.
