Hi all! I know figuring out the optimal series / parallel wiring for a charge controller can be a chore, so I created an interactive series parallel calculator.  

I added animations and visual cues to help the viewer better understand what's going on instead of just spitting out numbers
  • Size of the "packets" correlates to voltage - bigger packet higher voltage
  • Distance between packets correlates to current - the closer together the higher the current

    • I also added details like accounting for ambient temperature effect on voltage.

    Happy to hear any impressions or suggestions.

    Hey Josh, that looks really handy. Welcome to Permies!
