Not sure that article is accepted by the LFP owners here, but it rings true to me FWIW. Doing research, you know not to just read one author on any subject. You have to read several and get a feel for what is most likely. Papers have a similar rule about needing more than one source before printing a story.
I am on about monitors and how to zero them here because the OP could use that before deciding on the rest of his set-up.
Since it is important to operate avoiding the lower knee especially, and you want to exploit the LFP's lower SOC operating range (that you paid for!) you need to know when you are getting down to that lower knee with some accuracy. That is what the AH counting monitor is for, but it needs to be zeroed to stay accurate enough to do that for you.
A separate issue is avoiding the upper knee if that is the plan, when you have solar. Seems like you will be going past the upper knee quite often with solar. You can set the solar Vabs under the dreaded 14.6v, but how can you turn it off if you get to the top mid-day? Different issue though.
