﻿## Phase changeover
Phase changeover is used to charge the charging point optimally depending on the PV power currently available.

If there is not enough power available, the system switches from 3-phase to 1-phase charging.

If the charging point does not have an internal contactor, the "Phase changeover contactor" group object is enabled. This must be linked to a KNX switching actuator, which in turn controls the power contactor for the phase changeover.
