Yup it looks like the switch is dead

Other than the fuses, there's no breaker that I've found from the converter to the battery, self-resetting or otherwise. The fuses inside the converter all checked good, so that narrows it down to the switch itself, and a replacement is due in early next week.
Behind the batteries on the wall are two red plastic covered self-resetting breakers. See the picture below. The left one is notorious for being undersized. Read this Thread to learn much more than you ever wanted to know about it and what to replace it with.
