I seem to have a good problem to have but I'm worried about the effects on my batteries.
I have two 12V 206Ah LiFePO4 batteries in series (24V) and 990W of solar (3 330W in series) setup for my cargo trailer camper. On a sunny day I can run the A/C from noon until an hour or two after dark, run the fridge, charge my phone and laptop, and use a few lights. By morning my battery is only down to 85% SOC and the solar has them fully recharged well before noon. If I don't run the A/C after dark the battery is never below 95% in the morning. I've only been doing this for about 2 weeks so not a lot of data yet.
Basically my LiFePO4 batteries have only been below 95% SOC twice in 2 weeks. I'm sure a few cloudy hot days will give me a chance to get the SOC lower. But with the Fall coming there won't be many more days of A/C use.
It's my understanding that LiFePO4 doesn't like being kept at such a high SOC all of the time. Would it make sense for me to throw my PV disconnect breaker for a few days and let the SOC get down below 40% or 50% once in a while for the sake of the batteries?
I have a Victron 150/45 SCC but I don't any setting to say "hey, let the batteries get down to X before trying to charge them".
