There’s no way that would work without additional active components moving air or liquid to carry the heat away from the individual boxes. And that would be much less efficient than a one big heat pump and battery per shipping container. I don’t think anyone is planning on using them that way though. I shouldn’t say no way. Maybe if you cooled the boxes down to temp before stacking them in racks with spacing and they were very well insulated, so that the heat pumps almost never ran while stacked.
