mppt vs pwm
Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm

You're only at the maximum power point of the V-I curve during bulk. At that time the battery can take a lot of current. Once you get into absorption mode, the battery can't handle high current. The mppt controller now outputs a fixed voltage, say 14.4V. The operating point of the V-I curve is no longer at the maximum power point.
mppt has a slight advantage over pwm only in bulk mode. There's no advantage in absorption or float
What is the panel voltage during Absorb or Float when not in MPPT? It is no longer Vmp for sure with no MPPT but what is it? (I asked earlier but got no takers)
The "Rogue Guy" seemed to say earlier that the controller lets the panel voltage equal battery voltage when it drops out of MPPT. ???
But then how does the buck converter get back in business- but without MPPT- whenever you turn on a big load?
( I hope Salvo has not annoyed the "Rogue Guy" so much he has gone away--Salvo, there is no need for that sort of behaviour. Agree to disagee-- We need to hear from these expert people.)
