I have an oversized LIFEPO4 battery bank and oversized panel array. In typical use I'm only depleting ~10% of the bank's power overnight and am fully charged by just 10-11am. This means the batteries are sitting near 100% SOC for the majority of the day. Should I be concerned about potential degradation of the cells in this scenario?
I've manually changed the high voltage cut off to be about 95% SOC, thinking that it's probably not best to sit at 100%. Should I consider something lower, like say 80% SOC high voltage cut off to get the longest life span out of these batteries? From what I've read I can expect the most cycles if I stay within the 20-80% SOC range. It's a shame to not take advantage of the full battery capacity, but if that means I can get more cycles, it seems a worthwhile tradeoff.
System specs:
12x Lion Energy UT1300 wired series parallel for 48v
18x 250watt panels
