Discussion here might be getting ahead of the actual situation. We don’t know what the parking arrangements are. Perhaps each unit has its own garage/carport and can have an ordinary 10A power point for charging behind its own meter in its own garage. This is unlikely to cause any problem.
Unit owners might be encouraged to use their own solar if they have it. They might sign up for a time of use tariff or other EV-specific tariff that give cheaper charging in off-peak times.
