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

So, is the "mppt-capable" controller still doing something the pwm cannot do? IOW, Can the pwm raise or lower panel voltage to accommodate for variances in lighting, or just for variances in Vbatt?
dunno about pwm controllers.
But JiminDenver's quote about MPPT controllers pretty much agrees with Rogue's manual. Rogue talks about occasionally doing a "sweep" of the panels (guess that means changing the voltage and seeing what happens), especially when changing modes. And it the frequency of "sweeps" can be adjusted.
But it also "dynamically" checks panel output as well without a sweep. Much of this is probably proprietary, but my guess is that in MPPT mode is constantly trying adjacent voltages to see if the current output increases.
