It's a completely new hardware design with the power cabinets now using industrial inverters. The old v2 cabinet used a bunch of Model S inverters. The power posts (the white things with the cables on them) are the same as v2 externally, but not internally.

They're not retrofitting stations, but all new stations (other than Urban Superchargers, which they will still install in urban locations) will be v3 hardware.

For the cars, accepting the higher charger rate is 100% software in Model 3 (because the cabling and battery already support it). Model S & X will probably need thicker DC cables to the battery to support the 250 kW peak charging rate.

They used a stack of Model S chargers, not inverters! An inverter converts DC to AC. Chargers, of course, go the other way.

Don't forget the software aspect that warms the battery prior to you arriving at the supercharger. That provides half of the improvement, according to their bar chart.

Said older models software upgradable to 145kw.
