Another problem would be that the battery peforms as a huge capacitor
for the alternator. The waveforms out of the alternator are pulsing DC,
and the battery will tend to level this out to a straight DC level
which the inverter likes a lot. Without the battery in the circuit, the
alternator may not even start up, as it requires excitation voltage on
the field to start up with. I am not sure about how it will behave with
just pulsing DC for a source either.
Interesting though..anyone want to try it?

The alternator needs to always have a load on the output to keep the
voltage from going too high and burning out the diodes (integral to
the alternator). Normally the battery provides this constant load.
The risk is that your inverter might have a mode where it turns off in
some way, leaving the alternator unloaded, and leaving you looking for
a replacement. I'd leave the battery in the circuit, why take a
chance?
