The IQ Cable is available with connector spacing options to accommodate the installation of PV
modules in portrait or landscape orientation. For IQ Cable ordering information, see
Cable planning and
ordering.
Compatibility
The IQ8P Microinverters are electrically compatible with PV modules as listed in the following table.
For specifications, see

compatibility. To ensure mechanical compatibility, the microinverter's male and female connectors
must only be mated with the identical type and brand of a male and female connectors.
IMPORTANT: The IQ8P Microinverters include both AC and DC connectors integrated into the
bulkhead. The AC port connects to IQ Cable or Enphase Field Wireable Connector. The DC port has
been evaluated by TUV for intermateability with Stäubli made MC4 connectors, whose cable coupler
models are "PV-KST4/...-UR, PV-KBT4/...-UR, PV-KBT4-EVO2/...-UR, and PV-KST4-EVO2/...-UR". The
DC port of the inverter must be mated with Stäubli made MC4 connectors.
WARNING: Risk of fire. The DC conductors of the PV module must be labeled "PV Wire" or
"PV Cable" when paired with the Enphase microinverter.

NOTE: Some Enphase microinverters will not begin exporting power until the IQ Gateway is
installed and has detected all the microinverters at the site. In addition, the grid profile
needs to be configured and the IQ Gateway must have propagated these settings to the
microinverters. For instructions on this procedure, refer to the IQ Gateway Installation and
Operation Manual at https://enphase.com/en-za/installers/resources/documentation.
Earthing considerations
The microinverter has a Class II double-insulated rating, which includes ground fault protection
(GFP). To support GFP, use only PV modules equipped with DC cables labeled PV wire or PV cable.
Refer to local electrical codes and standards for earthing requirements of PV array and racking.
Branch circuit capacity
Plan your AC branch circuits to meet the following limits for a maximum number of microinverters per
branch circuit.
