Also didn't see any mention but direct DC to DC fast charging to the car doesn't look possible?
With 2 kW power it wouldn't do any good anyway.

I still don't see how these would be wired into the house for daily use, as distinct from emergency use, because of the 2/3.3 kW limit. That would barely cover 2 120V 15A circuits.
Do we know if the 2/3.3Kw limit is per pack or for the whole system. That is, if you buy the largest possible 90KWh system (9 powerwalls tied together), would you still get 2Kw power or 18kw? Also, the 3.3Kw peak--how long can the pack supply that? Long enough to use a toaster?
Ah - of course, that makes perfect sense.When not in a backup /essential loads set mode, they are not tied to any particular circuit. They just would just add up to 2kW to the total power for your house. Sort of like a 2kW output Solar panel was added.
Not initially. Tesla's press kit said it would start in the U.S. and then roll out to other markets. Given the different electrical specs from country to county, this seems like a rational approach.Will the power wall be available in Italy?
More specifically:It was mentioned in the quarterly report that there are different chemistries between the 7 kWh and the 10 kWh packs.

Not "some reason". The chemistry and design intent are different between the two species of Powerwall.For some reason the 10 kWh can't be cycled regularly and can only be used as a backup. That sort of torpedoes my interest in the system. Oh, and solar city will only be installing the 10 kWh variant, not the 7.

Per your post above, the 10 kWh variant uses the same chemistry as those in the Model S. Now, I cycle my MS pack much more than 50 times a year - in fact, I cycle it to some extent everyday. Not sure I see the logic.
Right, so then I guess I don't understand why the 10 kWh battery can't be used for anything other than backup. It has a BMS so presumably it can be made not to fully cycle unless it's actually needed (i.e. no grid power).
