Yes, absorption is very long.
I’m not home now but I’ll post later a graph where you can see that.
After going under the threshold, I have seen 56V from maybe 10:00 until 22:00, when the MPPT can’t hold the house anymore and the battery starts to get lower. The next day it won’t go to 56V but to 54.8V if it didn’t reach the threshold.
I have 15 sec resolution in home assistant.
