A faster deployment because the V4 Cabinet is able to power 8 stalls which means 2X stalls per cabinet. Because of the lower footprint and simplified design, more sites can go online more quickly.
Last year, Tesla started to place the V4 stalls in Europe and also in limited places in the U.S. Unfortunately, these power stations have limited capabilities similar to the V3 Supercharger and support only a maximum of 250 kW when charging. But, these upgraded V4 stalls also include a physical payment station, a longer cord to be able to charge other electric vehicles besides Tesla's new EVs, and CCS connectors to facilitate the charging of EVs without the need to bring your own adapter.
However according to the Tesla EVs automaker, these V4 cabinets power up to 8 stalls each. This means that different EV manufacturers such as Porsche, Hyundai, Kia, and others will be able to have a faster charging speed after previous experiences with a slower charging time with the V3 Superchargers because of their low voltage charging option.
In the early stages of the Tesla V4 Supercharger network’s deployment, the company guaranteed that would equip all the charging stations with solar arrays and batteries, in order to operate without a power supply.
Tesla did indeed install some solar panels along with batteries at just a few stations, but the majority of these still don’t have an independent power system and only have minimal solar features
