I have a 200w solar panel with 22 volts, open circuit. I have a DROK brand buck converter rated for an input of 8-22v with an adjustable potentiometer that allows an output between 3 and 15 volts @ 3 amps (up to 45 watts). I am wanting to power a 12v heating element that is rated at 25 watts, so it basically draws 2 amps. Can I connect the panel to the buck converter, set the buck converter to ~13 volts output, and wire it (with a fuse) to the 12v heating element?
I know I can do that, technically, so I guess my real question is; will this setup work to power the 12v heating element, when the solar potential at the panel is high enough to create sufficient voltage? (Yes, I know this panel is probably larger than I really need.) Is there any danger to wiring something directly?
