You have a bad house battery that's setting the alarm off and putting out a sour smell. It may be too late to add water to the battery but worth a try. Sounds like you have a single stage converter that's boiling the water out of your battery.
Say,,, this could be.
You said in your first post that you tested the fridge and it still worked. I was wondering how the fridge could still work if the refrigerant had leaked out. You would think that if you smell ammonia that it would not longer work.
It just might be a battery. Worth checking out.
