I wonder, the twin charger, is it necessary? Elon have confirmed that eu-cars will be suited for 3 phase charging. How does the twin charger work? Ex: Do I have to have 2 separate 240v 16 A outlets with separate fuses to use the twin charger ? If so, why not install 240v 3-phase 80a in your garage?, or even 240v 32 amp will charge quicker than 2x16a 1-phase, or am I wrong? Do I have to have twin charger to use the supercharger? is it possible to reinstall twin charger later?
