What is the voltage at the battery? Just because the cells have electrolyte doesn't mean they're good or charged.
Anyhow, assuming the battery is at all responsive, the problem would seem to need to be an open connection between the battery and the DC distribution panel. When plugged in to shore power, the converter is supplying 12V power and the rest of the DC distribution system is working. The first thing to check is the battery shutoff switch (often called the "salseman switch" for reasons that I'm really not entirely clear on). Try cycling it off and on.
If that's not it, you need to track down where the battery connection is lost. It may be a wire that's come loose, or a blown fuse at the battery. Check the ground as well as the +12V connections. Also make sure the battery cables themselves are good; I've seen a couple of battery cables where the outside looked more or less okay, at least at first glance, but the actual conductors had corroded away to nothingness within.
