100kWh over say a 5hr charge is 20kW. At 12v that would be 1666A. For 5
hours means charging input of 8333Ah. If we allow 10% losses then
you're looking at a 7500Ah 12v battery. Compare that to your typical
33Ah car battery... its equivalent to 227 car batteries.

Where could you phone with that? Pluto maybe?

I wouldn't say a 33Ah battery is the typical capacity of a car battery -
more like
50 to 90 Ah...
