4.6 IQ Cable planning and ordering
The IQ Cable is a continuous length of 12 AWG, double insulated, outdoor-rated cable with integrated
connectors for microinverters. These connectors are preinstalled along the IQ Cable at intervals to
accommodate varying PV module widths. The microinverters plug directly into the cable connectors.
The cabling is compatible with a variety of PV racking systems. For a list of approved PV racking
systems, refer to the PV Racking Compatibility document on the Enphase website at
enphase.com/support.
4.7 Connector spacing options
IQ Cable is available in three connector spacing options. The gap between connectors on the cable
can be 1.3 meters, 2.0 meters, or 2.3 meters. The 1.3-meter spacing is best suited for connecting PV
modules installed in portrait orientation, while the 2.0-meter and 2.3-meter spacing allows you to
install 60-cell and 72-cell PV modules in landscape orientation, respectively.
