Just chiming in here with something that seems to not be discussed when deciding on charge controllers.
Built in bypass diodes in PV panels, not all of them have them but many do. These panels would really only properly work with mppt charge controllers as they will drop voltage during partial shading.
Yes they do confuse the MPPT charge controllers and I can attest to that. I recently swapped out my older Tracer mppt charge controller for a new MPPT to see if it would overcome the inconsistent voltages the controller would hold the panels at.
Will post my findings after a couple weeks testing.
This is an interesting point, something that never crossed my mind, and afaik Dacian has never discussed. I would be curious to learn more about how this would play out in different scenarios.
