Good question! These are V3. You don't get much chance to see them in the pictures from this site, since they're mostly hidden either under their shipping covers or behind the brown walls of the equipment enclosure. But they are visible in the photo in post #152. They're the slightly smaller cabinets on the right. The V3 superchargers have a distinctive 4-sided symmetric appearance, with straight sides of equal width and a grille panel at the top of each side. The V2 cabinets look narrower, and are not as symmetric, with a ventilation scoop on one side. After looking at enough construction photos from other sites, you will be able recognize them in their shipping covers and even from the conduit pattern where they will be installed. On the charging pedestals, the cooled V3 cable is thinner. PLUS EV points out that V3 also has a metal ring at the base of the charging handle, but I have trouble spotting that in photos.
