o
If the number of microinverters connected to C1, C2, and C3 types of
connectors is not the same, refer to local AHJ rules for acceptable phase
imbalance across the system.
o
Enphase Installer App provides phase connection details during the array
builder or commissioning process. Validate your imbalance expectations
through the Enphase Installer App.
o
Enphase Installer App shall be able to share a consolidated report of all microinverters
with each phase connection.
