I agree you may have disconnected the batteries from the converter so now they are dead but your lights still work on shore power.
Besides any battery disconnect switch that might have been opened by accident, there should be a "battery fuse" close to the battery on the positive wire. Somehow you might have blown that.
You can try to recover the house batteries by first recharging them to about 14.4ish volts till they won't take any more amps (that 7345 will only do 13.8v so you need a different charger like a manual 6a that is not an "automatic" but which you have to turn off yourself when the voltage gets up too high) then do an Equalize for a while to see if you can get the SG into the green with your hydrometer. This will all take a few days, no instant answer.
