However...since the Morningstar is not intended for lithium....I get no answers from their tech service. I am seeking answers here on how to set each and every parameter on the Morningstar. That is my original question.
OK, I'll try to remember to leave the voltage issue alone for you, you've certainly gotten that input.
What else do you need that isn't covered in my canned blurb?
Hit your voltage and stop, that is all, no Absorb stage, no Float.
Since no charge source does that automatically, see if you can remember to do it manually whenever it's convenient.
Unless you want to try my previous suggestion to use an adjustable OVD relay to cut the connection between the panels and SC.
The real-life compromise all LFP owners I've discussed this with do, is:
set Absorb hold time to absolute minimum, adjusting target V down if that has to be more than a few minutes.
and set Float to 13.1, so there is no actual measurable current flow.
Put your clamp meter on, and make sure you are **not** letting trailing amps drop below 2-3A (opposite of Lead logic). With that higher voltage personally I advise using 5A.
All these suggestions are based on the original objective of avoiding damage to longevity which comes from overcharging.
That high Absorb setpoint is already taking you way past that point, so IMO it's even more important for your case to follow them.
But the "canned" LFP settings on the Victron unit (which I also told you to avoid) would probably have been just as bad or even worse.
I have been told by authorized Victron dealers, that they were designed to work strictly in conjunction with the Victron packaged LFP systems, large prismatic cells managed by their proprietary external BMS. I think it's possible the two devices are intended to be coordinated with each other, perhaps by an AH counting calculating device.
Since all the charge profile parameters are at least as adjustable as the Morningstars (AFAIK) IMO that is the better way to accommodate non-Victron batteries.
Again, there are no charge sources on the market claiming to be LFP ready that actually do the right thing.
The key to success is user customizability of the setpoints.
So, if you have questions on the meaning or ramifications of any of the programming options on the Morningstar unit, feel free to ask about them, ideally one at a time, and we'll do our best to help.
