Running 12v appliances off a 24v pv system

[marsofold]

In a SHTF situation, could one just use a small 12 volt solar panel across the output of the solar charge controller to "deceive" it into thinking that there is a battery present, then once it turns on just use it to power loads afterward connected to the charge controller's output?

No. virtually all charge controllers need a battery to work properly. In particularly they need the capacitance of a battery. The battery can be nearly dead as long as it has some capacitance.

By the way, the answer I have given has already been given and explained in this thread.

Jim, have a read of section 10 in this manual it gives a good explanation of charging and sulphation, from a different battery maker.
Ps they have a different view of charging AGMs
