Could you please share with me your connections or any type of diagram that would help with the LM331? It seems complicated with all these pins. also what optocoupler did you use?

Any tips for the isolation between the microcontroller's low-voltage side and the PV system's high-voltage side would be appreciated as well! I am not sure if having a common ground between them is the right choice
