I would suggest emailing Will Prowse, or Jehu Garcia. See if he has any suggestions. I think your solar panel controllers are overheating. Perhaps insulated them somehow might help or consider looking into replacements. Some panels only last ten years.
@thiscantberight That is great news, I will do that, once I reach my base (soon😇).
Blessings!
