- mateus1 10y ago14/9 is not double.
- givinguflac 10y agoIt's still nearly a 65% increase, and includes the inverter. I don't see how the PW2 isn't a better deal.
- BrittTheIsh 10y agoThe powerwall went from 7 to 14. Double.
- mateus1 10y agoDoh! I stand corrected.
- amluto 10y agoIs it a string inverter? Is it compatible with DC optimizers? Can it provide backup power in the event of a grid failure?
- codecamper 10y agoThey 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!
