I see that the optimizers are described as allowing a bypass tunnel to keep one panel from dragging the rest down. This works for shading but their must be more for mismatched panels, it says the optimizers runs from 0volts to the VOC. So if the panels are mismatched slightly is it just forcing thoes panels to stay a bit above their mppt voltage in order to match the rest of the strings voltage? Also it mentions different length strings as well which makes me wonder how that would work as it would have to boost the output well above the panels VOC to make the strings work.
I guess to put it simply is this just only acting as a MPPT per panel or does this actually have boost/buck electronics in it as well to help with the mismatches and shading?
