Inverter Low Voltage Cutoff--Why SO low?
A great many loads draw high initial current surge at turn on, and the surge may only last for a second or less. So the voltage may briefly dip below 10 volts for an instant, then spring back up to maybe 11.2 volts. Now if your inverter shuts down at say 10 volts, you might have very frequent shutdowns even with the battery at 11.5 volts.

The standard voltage of AA batteries is between 1.2 and 1.5 volts, with different chemistries offering different capacities. It highlights the importance of the relationship between charge and voltage, noting that a fully charged battery will have a high voltage but over time, the voltage will drop as the charge depletes.
IV Curve
The IV curve of a solar cell is the superposition of the IV curve of the solar cell diode in the dark with the light-generated current.1 The light has the effect of shifting the IV curve down into the fourth quadrant where power can be extracted from the diode. Illuminating a cell adds to the normal "dark" currents in the diode so that the diode law becomes:

How to keep solar panel voltage at 24V?
As a result the voltage of the panel drops to the voltage of the load. For example my 12 volt panel that reads 20.5 volts in the bright sunlight drops immediately to 10.5 volts, to when I connect it to my depleted lead acid battery (which is 10.5 volts when completly depleted). I would think that the same should happen to your fans.
