does the Powerwall use a auto transformer to create the neutral leg for 120v

does the Powerwall use a auto transformer to create the neutral leg
Presumably it is a balanced source of power. I know my Enphase micros do not even have a neutral. Do we even know if the Powerwall has a neutral? I know my hybrid inverter has a neutral because it is connected to the subpanel which may present unbalanced loads.
 
In the disassembled photos that I have seen, I haven't seen an inductor of the size needed to balance a neutral.

More to the point, when you have a digital power supply that continuously outputs a 120V sine wave with respect to ground/neutral, there is no need to have a load balancing inductor/transformer, as the balance arises out of the power supply control circuits automatically.

Stay safe out there,
