[RE-wrenches] Schneider CSW4048 / Lithium DD5300

[Dave Angelini Offgrid Solar]

Mine work fine closed loop with Discover AES only. I doubt there is much 
support on other batteries as they all use XW pro which uses the RS 485 
protocol to close the loop with different battery brands.

To get it going open loop you would use a custom battery menu and 
probably need an external battery mon and shunt.

Ouch !  Sorry about that. Going to be a project!

With an AES : 42-48-3000, 42-48-6650 it is just plugging in xanbus and 
you are done.
