Troubles powering PWM cooling fan from solar panel
valley001:
Well...i'm not sure if the buck converter/booster will work or not. In fairness we did not have good sun today until the evening when solar energy would be low anyway. One encouraging result is with poor sun the fan draws voltage down to the point the converter resets, so what I end up with is a fan that cycles on and off every 10 seconds or so. With full sun it should run full out, if obscured by clouds it should drop, reset, and resume at full power with full sun. I guess ill see.
Will this cutting in and out potentially harm the electronics?
