If you get the full 12kWs, do you still get storage and USB chargers?
The initial pair of 3kW chargers fit under the tank storage, but the additional 6kW unit that brings it to 12kW seems to sit where the tank storage goes, so it's either like the existing Charge Tank or it IS the existing Charge Tank.
So, it probably replaces the storage but probably not the USB port since that's pretty cheap to move elsewhere.
