[RE-wrenches] Enphase grid tie question

[Jesse Dahl]

All,

I'm looking for ideas on the electrical integration of the following system:

800A service 
PV system employing enphase 215W inverters broken down into 8 output circuits.  Each circuit will be 208V 3 phase 20A.  

The question is on how to grid tie this.  My first thought is a sub panel for PV intertie only.  I saw a similar diagram on the enphase website, using 5 circuits and a 125A panel....  

What are people doing in situations like this?

Thanks as always.
