I reserved one on the first day I was allowed to. I just checked my confirmation email and it stated that power walls will be shipping nationwide by October. It is now 6 months past that and I haven't heard a thing. Anyone have any info?

Same here. I reserved it twice last year when I ordered my MS. That was 65 months ago. No calls , nothing ,
Actually, a sales person contacted us and offered us Powerwall(s). However, after discussing the installation arrangement it was clear that he didn't have much background in electrical system interfaces and refused to sell to us, based on the way we intend to install them.
That was OK, since we really need a small Powerpack rather than a string of Powerwalls.
As background and maybe off-topic, we have 6 Solar Edge inverters running a 33Kw system ground-mounted about 1,000 feet from our home. Even at a slight sacrifice in round trip efficiency, we are going to install our storage in our home's electrical room, add the associated hardware to integrate the pack with the AC lines and panel and we're good to go. Didn't seem that hard to understand, but the sales person couldn't do so. It sounded as if he was working mostly from scripts.
Replacing six inverters and rewiring the system (and perhaps building a shed for the Powerwalls and additional controls) would be prohibitively expensive. Most of us with existing systems are going to have the same problem with the installation of storage.
I understand your issue with energy efficiency, but in my case there is a pricing efficiency. My solar generation gets paid $0.37/kwhr and I can charge my car at $0.11/kwhr. My separate inverter/battery system just takes care of my critical loads during the day so maximum production gets paid at max rate and I also charge those batteries and my cars late at night at the low rate. Even though my round trip losses may be 20-25% the economic advantage of that arbitrage is compelling.No sense in losing energy just to move the energy from component to component.
I understand this, but I think you are on borrowed time here. The utilities in California are doing what they can to eliminate this feature and soon the only value in solar is that you will be cheaper than they are.I understand your issue with energy efficiency, but in my case there is a pricing efficiency.

Utahken,I'm in Michigan, so a least they are talking to people in the Midwest region. Does your reservation for the powerwall show up in your Tesla account?
Mine does not.Does your reservation for the powerwall show up in your Tesla account?
I am not sure what "feature" you are talking about. If it is net metering, it is grandfathered in for existing users. What pricing model will make my system not have a positive payback? I know this is a Powerwall thread, but we are discussing the economics of employing battery storage........I think you are on borrowed time here.
