I have 3 280Ah indoor batteries. 

According to the paralleling guide, the recommended installation is to connect the FlexBoss wires to battery number 2.

In my particular setup I need to move the inverter over battery number 3 due to the layout of the house. 

Is there any reason why the batteries can't be wired up so that the inverter connects to battery 3 instead of battery 2?

If you connect the inverter to the third battery, it will draw power from the third battery first, then the middle battery, and finally the left battery. This will create an imbalance between the batteries. It will still function, but the batteries will become unevenly discharged.
