so if I understand what you're saying....
all loads are powered by the battery
the converter's job is only battery charging.
I've thought of that a few times myself. The only real hole I can see is in the case of a shorted or otherwise kaput battery... you're in the dark, no choice. Another similar example...I've read folks that are permanently plugged in asking if they even need a battery. Some folks just want it to be more like a house I suppose....
