Perhaps it was due to charge efficiency? The Trimetric uses 94% for 6% average heat losses across the SOC range . ISTR it was posted here that Bogart recommends using 99% with LFP? So if the Xantrex one is like that, it would get out of whack with the LFP.
Eg, when the LFP has taken 100% of what it was down, and 1% of that was heat, the monitor should show AH restored as 99. With the FLA, it would show 94% restored.
The Trimetric has a way to set the charging efficiency factor to something else instead of 94 if you find it is not right for your set-up
BLF, That’s a dang Good point you make, as I just checked the online set-up instructions and there is no programmable setting for charge efficiency (huh?), so this may be why it was inept at tracking SOC! - I’ll accept this as ‘mystery solved’ and with a spare meter at rest on the shelf...But much prefer the Victron’s detailed smart phone display anyway - a much more informative and cogent display...
