So I am designing a solar charge controller for a 30 W solar panel with following specifications:
Vmp=21.5V
Imp=1.71A
Voc=21.6V
Isc= 1.85A
I am planning to connect the controller to a 12V battery. So the question is do I need to use a buck converter or a buck boost converter and why?
Lol let me try at least, that wouldn't harm anyone would it? In most of the videos related to designing of solar charge controllers on Youtube, I have noticed that they have used buck converters. So my question is why aren't they using a buck boost converter?
