SoloCam 40 Power Setting

My SoloCam 40 died despite having the add on solar panel connected. I pulled the camera and charged it. It doesn’t appear to be charging. Should the Power be set to Battery or Solar?

Make sure that your panel provides 5v voltage and not more, because then the camera will not charge. For example, popular reolink panels give a voltage of 6v which is too high, while requiring stabilization “step down” to 5v.
The battery or solar setting is basically irrelevant.
