How/why has my battery SOC decreased from 88% to 81% overnight with no battery discharge? System is 18kPV hybrid inverter with 2 - 280Ah indoor wall mount batteries.

Why is SOC decreasing v1

And it is still happening - day 2. Am I powering the universe?

Why is SOC decreasing day 2 markup

I do not know if it is significant, but when I "READ" this, it always times out. So there is some sort of communications issue with the batteries.
