Solar has been working great for about 2 years. Took my trailer to the desert in June. After 1 day there the solar stopped charging.
Upon inspection, I found the power wire melted pre breaker… what happened??
Looks like a bad connection that heated up at the terminal and melted everything around it.

Replace breaker and wire?
The breaker definitely replace.
If you have slack on the wire you could probably trim back to where the insulation and cable is not compromised.
As an fyi in movile applications regularly checking connections is a good idea, vibration does all kind of interesting things.

Also, brace cables to avoid movement induced fatigue.

Loose connection.
Going forward at least yearly check all connections are tight.
