[RE-wrenches] Closed Loop comm LiFePO/inverter options

[Dave Angelini Offgrid Solar]

There is an announcement next week of another battery that will close
the loop with XW pro. It really is a matter of entering time and date and
you are done. You do have to install the equipment still.... 

Meets UL
9540 also. Will start any motor that a home would have.

whole house transfer (200A) PV systems with zero export to grid (utility
doesn't offer net metering so it makes no sense to sell to grid), LiFePO
batt's, and 10kVA+ gensets.    We did this a couple of years ago with a
Schneider XW+ system with LA batt's and a Brigg's/Symphony X-fer (that had
to be field reconfigured for AGS due to lack of 2 wire start), but it was
not exactly a straightforward install and the system owner has never really
mastered the operation of the system. I would really like to have closed
loop comm's between LiFePO batt's and the inverter/charger. I've seen a
number of references to SolArk on here, but I've also seen references to
those inverters not being able to run motor loads (which seems REALLY ODD
is this true?).   These homes both have 1 or 2 - 5 Ton heat pumps, Fridge's
and Freezers plus all other regular house loads that they do not want to
leave off in the event of a grid failure (somewhat frequent). My preference
would be to use LA batt's, but these customers are asking strongly for
LiFePO.   So, I'm reaching out to you guys to find out if you've come up
against this use case to see what equipment you're using? And before anyone
suggests critical loads panels - these people do not want that. I know...
