Tesla version integrates the inverter and has double the capacity(14kwh) for the same cost as LG Chem REsu 9kwh version

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!
