Can Tesla batteries be used as home storage?

May I ask, what the kWh at Superchargers costs today for Tesla users?

Unfortunately, you can't generalize as easily as "in the past" anymore. It depends on a few factors. Supercharger version (V1/2/3), peak times, whether it's part of a charging park, frequency of use. I'd say currently 38-52 cents. For Tesla customers.

Sounds complicated. EnBW with L tariff (39 cents + 17.99/m) is actually pretty good for frequent drivers. In my opinion, it's available at every Hellweg and many Burger Kings.
