[RE-wrenches] Schneider XW+ and Midnite batteries

[Jason Szumlanski]

My understanding is that Schneider is out of the off-grid solar business
and the XW / Conext is discontinued. I am not supporting any LFP
replacements on Schneider inverters. I would push for an inverter
replacement with the battery replacement if switching from lead acid to LFP.
