Mods: Please roll this into any other existing thread on the technical side of the Powerwall discussion... So, The PW is a 350V-400V DC battery. Put differently, it is a 10KW-Hr version of the MS battery. This tells me that there are inverter companies out there working with Tesla to do 400V battery supporting systems. This would also make me think that those same inverters would manage PV to PW DC charging without having to go through the AC state (DC PV inverted to AC then fed to a charger for the battery which returns it to DC). First, does anyone have any knowledge of, or experience with this type of inverter/battery manager? Second, is it not now time to use all those salvage MS batteries in combination with the above described inverter to build VERY cost effective home storage systems?
