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

BFL,
If panel Isc is say 7a, at 14.8Vabs, then in series it would remain at 7a, but in parallel it would double to 14a. So in my example, when the switch happens from bulk to abs, there would still be a sudden and significant drop in current... 14a down to 7a, instead of 16.4a down to 8.2a. So the issue would still exist, correct?
------------
I do keep forgetting about that 13.x volt kick in setting.

But, apparently, Jim sees current above and beyond Isc... while still in pwm mode. How is this possible? What, other than the bucker, could do this?
