Does the house 12V system work normally, particularly off of battery power? My guess would be no.
Often there's a disconnect solenoid (a latching solenoid, so only energized to switch between on and off) between the house battery and the house 12V system. Maybe it's not working or not turned on. If there is one, there should be a bidirectional momentary switch to turn it on and off somewhere. If the solenoid is defective, it can be bypassed by connecting the two heavy power wires to the same terminal on it.
It would also be good to check the main fuses on the 12V panel and/or the "reverse polarity protection" fuses on the converter. There may be a separate main fuse at the house battery connection or a self-resetting circuit breaker there that would be worth checking, too.
