I was asked if a post in another thread if this "Serial is actually better for shading (than parallel) if that is a concern for you." was a typo. It is not a typo but panel shading is not always under...

What PWM controller does is switching the current on and off at BATTERY voltage once it starts controlling.
So does MPPT, That is how they LIMIT energy when it is not needed.
As this happens the reported panel voltage rises sine it is an average of battv & Voc or Vmp and Voc. The more the off time is the higher the average voltage reported.
