Oversizing the inverter for future expansion of the array?

Are there reasons not to do this if we think we would like to add more panels in the future? Would an oversized inverter operate at reduced efficiency compared to one that is sized to exactly match the array output? Would it be better to just install a larger capacity inverter when and if we expand the number of panels? (We are thinking we might want to add panels later for a future electric vehicle charger, but this may be some years in the future.)
