do you know where i could find a short circuit protection schematic for the AC output side of an inverter?

 

 

Could not have said any better.

Although he could use overload tripper at the battery side and CB at the output too..

 

Fuzing drive outputs isn't the norm. There are circuits inside most drives which take care of motor protection. Refer to these manuals from common drive manufacturers:


Lenze Drives, not output fuzing shown :

Yaksawa drive manual, no output fuzing shown:

Allen bradley manual, actually recommends against it:

 

sorry, I was on a roll about 3phase motor controllers (also called "Inverters"); if that's not what you were talking about then please ignore.

 

True that VFDs provide overload protection, whilst overcurrent is in the form of supply line fusing/breakers.

You have made a good point in that further clarification should have been sought.
