I can't read the graph very well
If you say that is what is happening, I'll take your word for it
But that is not what I understood hint to be saying
With my 12v 400Ah LFP system charging at 30 amps absorption only takes 10 minutes to go from 30 amps to 2 amps.
My CC is set to 14.4 and 13.4 float. Float won't happen very often because the voltage may still be above that level at sunset.
He doesn't say anything about how long it was at 30 amps
Or how many amp hours was returned
Or the state of charge before the sun came top
So I didn't take it to man what you guys say it means
But I will accept you explanation
