@NZ12VOLT ; that breaker on your solar cable looks like a C20 AC breaker. There are DC breakers available, and given its a caravan I'd recommend using a proper DC breaker as they have arc catchers, and will break correctly. AC breakers are not meant for this. On 12v DC for something like isolating a string of lights, an AC breaker is fine because you are using it for switching, not breaking. For your controller (Epever) you could be running anything up to 150v DC on that solar cable, so it pays to have a DC breaker.
