My original Enphase PV system was installed earlier this year. I'm now expanding the system by adding a 20 panel ground mount. Could you please give feedback on this one line diagram before I share it with my utility provider? I modeled this diagram after the one line diagram from the original PV system install.
Note: I'm de-rating my service panel in order to use a 60A breaker for the PV system. There is no permit required for this system (I live outside of city limits); however, the utility provider will be approving the system before interconnection is allowed.
The original one line diagram as well as the new diagram are attached.
