@mattesilver @TechConnectify batteries were mentioned in the video, in the context of how car batteries have been exceeding the longevity expectations by a lot
as for the smart, our installation is smarter than I'd like, requires a connection and sends data to a 3rd party, but when (not if) internet is not available it's still producing energy, storing it in the batteries and using it locally; I'm not sure about reselling it to the grid, but I think that would also be working. The part that will disappear if the company dies is just the data logging and reporting, and losing that would be bad, but not as bad as losing everything else.
