They don't really say.

I suppose the main reason for the inverter is to go from DC -> AC.

The Powerwall 1 required an external inverter. What did that inverter do? Converted from the DC -> AC? The Powerwall 1 had DC input? I guess not, otherwise you wouldn't need the external inverter.

So this powerwall converts internally from DC - > AC -> DC (battery)?

It's all very confusing!
