Just as the Model S has been sold as a 60, 70, 85 you will see varying capacities for the residential and commercial systems.
For comparison, a rack holding 12 AGW batteries runs $3,000 - $3,500. That's just the batteries and rack, no electronics that tie into the grid or panel.Anything below $10k excluding subsidies will be a killer in today's market, if it includes all the power electronics and controlling units, remote access etc i.e. "full package". I would like to see Tesla have a gross margin of +30% on these
Hmm.

$7500/3652.5 = $2.05/day + cost of money.
JB Straubel talked about a near-future $100/kW power electronics cost at the now infamous storage symposium.
So 10kWh/5kw => $500 power cost.
At $300/kWh => $3000 battery cost.
That's $3,500 for batteries and power electronics.
$x for everything else.
Let's say they want gross margin g.
I'm hoping that they've aimed for $5k before shipping, for psychological reasons.
Then
$5k = (1 + g) x ($3.5k+$x)
g = 20%, $x = $666.67
g = 30%, $x = $346.15
Maybe doable if they aren't seeking high margin? I'm hoping that Tesla is looking at this as a cell demand driver, in order to get the Gigafactory investment, rather than trying to make a fast buck on the back of CA's storage targets.
So, is anyone here a little bemused by the 8pm reveal of this? I mean is Elon going to "unleash the titan" holding a shiny battery for your garage? I'm just not sure how you can make an evening event out of just batteries. I would have expected a press conference or something. Ah well, I guess we'll see next week.
Well, at 8pm traffic will be sane and people can get there.
I'd have thought they'd do it around sunset to show a shift from solar to batteries. On April 30th, Sunset in LA will be at 7:36. Civil twilight will end 8:03pm.
Maybe they'll have the event running on solar-powered batteries to show how awesome it is.

Does anyone know if it's invite required or if it's doors open to all Tesla owners?

Pretty sure it will be invite required. I've been told I'll be receiving one, not sure when the official invites are going out.

May I have this dance?
It's an extreme long shot, but I would dearly love to see a Tesla riding lawn mower.
Try this one!

My guess is that roll out will be country-to-country for a while. First, Tesla may be using frequency-specific power inverters/rectifiers, and HK is on 50 Hz, while the US is on 60 Hz. Second, there may be differences in national electrical codes that will require country-by-country (or regional) certification. Third, there are likely regulatory issues that will require hand-to-hand combat with each regulator; one of the positions Tesla was seeking to fill was a regulatory advocate.
Not forgetting that the US is mainly Single Phase in residential areas where other places in the world use Three Phase in those areas.
The large(r) battery for industrial appliances will be Three Phase I assume, but the smaller ones might have Single Phase inverters at the start. Mainly focused on the USA.
I think it is more likely that the Model S will power the house. Slides of JB Straubel show these packs at the 5-10kWh range for a house and larger for commercial use.
