How to choose an inductor for a LCL filter?
As Andy aka and winny have pointed out using common mode chokes in this application is not suitable. 

Explanation:
As common mode chokes are used normally the core material needs to handle only the difference of magentic fields created by current going one way in the upper coil and the other way in the lower coil. Only if this current difference (may be some 10mA) is too large the core material will be saturated.

I.e. even if the common mode choke is rated for 3 A, it will be almost useless if too much current (some 10mA; much less than 3A) is going the same direction through both sub-coils (or only through one of them).
