I would happily go for one, if the current 13.5kWh costs $5,900 (plus $700 'supporting hardware') you'd think they could do something like you're asking for in the $1K range. I imagine they don't because they assume people are using so much power in their homes that a pack like that would only keep things on for a couple of hours. Of course, it sounds like the cost of the cells is a very small part of the price, some of which is the inverter and cooling, some of which is recovering R&D costs, but you'd think their profit must still be significant... ($6,600 installed, of which ~ $1,350 is battery, apparently).

Yeah, the sub-1K would be a resonable price point. A lot of place (including where I live) does not have peak metering. Essentially it will take over 20 years for me to breakeven for the power bank which really does not make sense at a financial point of view. I think a lot of people would want a 2 kWh battery hooked up to their existing solar setup just for emergency purposes. I live on the east coast and it would be perfect for the essentials. Just enough to keep the boiler going for hot water and a couple lights until the power comes back up. We get these short term blackouts (especially during snow storms) which is just long enough to be annoying (like 2-3 hrs) but not long enough to make bringing out the generator worthwhile.
