Had some excitement with my solar power this morning.
Bit of a plastic burning smell in the kitchen, traced to the wire from my battery breaker (at the breaker) to my battery. Cable burned, plastic on breaker terminal slightly melted. Turn everything off, remove a few inches of the burned cable and remade the crimp. Not sure why this happened, cable now cool passing the mid-day 25A at 55V from the solar inverter/panels, no voltage drop from inverter to battery. .........maybe just corrosion, but all the other crimps show no damage.
