mppt vs pwm
Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm
Forum Discussion
If voltage is lower than Vmp you get less power but go up in Isc on the IV curve, so to get lower power but also lower amps, you have to raise the panel voltage?
But if still buck converting, you get the output amps from the output power, not from the panel. So panel amps don't matter if they go up or down? Which means panel voltage could be more or less than Vmp in Absorb?
So the MPPT when not "in MPPT" (so it is in "PWM" but this means "now in PWM only" since it is also in PWM with the MPPT "on" ---if I got that right! :( )
So if PWM is always on too, then "panel voltage" is always on/off and is some sort of average amount- even the Vmp during Bulk?
