Do you have a reference for this? Tesla is telling me differently and I'd like a reference, or even better to see it in practice with someone who has connected the units. I'm happy to be corrected here, it will give us more options.
I am told the Wall Connector is designed for what the NEC calls a "Load Management System", which means that multiple units will coordinate to draw a maximum current as an entire system.
"Daisy chaining" has specific meaning, in that you connect conductors to the first unit's "input", then connect conductors from the first unit's "output" to the second unit's "input". While the Wall Connector has a "daisy chain" for the data bus, it does not have this capability for the power conductors in that there are no "output" lugs for power conductors on the units.
