I came across this and thought some people will be interested.

There is a huge lot of installations on boats.

What I found interesting is the battery with a built-in communication.

This is a state of the art a-z Victron installation.

Yup. The number of off-grid installations (including boats) completely dwarves the grid-tied installs. Not that the ESS market is insignificant... just much smaller than people think.
