Absorb cuts out (goes to Float) depending on current and/or time, not voltage.
It pulses. In other words, "cuts out" and back in again.
PWMs cut out (and back in) many times per second to regulate the battery voltage. In absorb, it's cutting out however often it needs to, to keep the battery voltage at 14.2v.
It'll shift the voltage set point from 14.2v down to whatever its float voltage set point is (say 13.6v) when current drops.
It will then keep cutting out (and back in) however often it needs to, to keep the battery voltage at 13.6v.
When I said, "cuts out", I wasn't talking about shifting the voltage set point ("dropping" from absorb to float). I was talking about cutting out. I.e., switching, a.k.a., pulsing.
Changing modes/stages is not "cutting out".
