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

So, it's not "looking" for anything at all, in other words, there simply is no tracking going on at that point?
On the battery side it's maintaining a constant voltage by providing the current needed by the battery and any loads.
On the solar side it applies the voltage needed by the panels to get the power required on the battery side (and any internal losses). That voltage required by the solar panels for a certain power output varies depending upon light conditions. And so the voltage will vary depending upon light conditions. Is that "tracking"?
It seems to me that MPPT is only different in that the voltage gets you the max power possible. Not just that needed for maintaining a constant voltage on the battery side. (and of course there's the algorithm for determining that MPP as well).
