I tried looking this up but found only one paper on the subject and it was not applicable to LFP.
My current system uses 16KWh of LFP batteries and these are turned on Automatically at 11pm and run until 5:30am. The Sun is up enough by 7:30am to fully power the house and start charging the Batteries. By 11:30am they are typically charged to 100% SOC and are cycling on and off a bit until 5pm to compensate for any cloud coverage on the PV.
After 5pm they are offline unless their is a power outage and typically get back some charge to go from on average from 93% to 95%+ SOC by 5:30pm.
Since I will be adding more batteries my question revolves around the Two hour time period in the morning when they are at 20% SOC and then start charging.
If I add one more battery I could remove that Gap and they would last until 7:30am and start charging back up again right away. I got a feeling that having Zero down time on a battery before recharging is not a good idea. Should I instead start using the batteries earlier from say 9pm and let them go to 5:30am and keep the 2 hour resting period in place? Anyone have any info on this subject?
