If your hooked to 120V, then you should also get 12V from the converter (on board battery charger). Check and make sure the 120V breaker connected to your converter is not tripped, or your battery will be dead again in short order.
Now, if the old battery had a shorted or dead cell or to, then the charger can't get the voltage up to around 11.5V or more, then the fridge and WH electronics won't let them turn on and it won't work even on 120V. Likewise for the furnace.
