After all, the optimizers only go around the shaded panels so that the current flows through it instead of through the diodes,

This is not the case with Huawei optimizers. The shaded ones still produce and are not "bypassed", below are the output power graphs of two topologically distant panels. Green shaded still produces although less and less, blue is not shaded.
The optimizer is a DC / DC converter controlled by an inverter, which communicates with it via a protocol on DC cables.

Please, yesterday, 1.5 first shaded by a tree from the west, 1.12 more or less in the middle.
This is the output voltage of the panel optimizers.

For comparison only for the shaded panel, the input voltage of the optimizer, i.e. the voltage
the output of the panel versus the output voltage of its optimizer - a DC / DC converter controlled by an inverter.
You can see how the optimizer lowers the output voltage to keep the output current at the level of the entire chain.

@jsw where exactly is this done? Is it via the www or is there any windows app?
