5.5 Enphase IQ Cable planning and ordering

The IQ Cable is a continuous length of 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.
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 meters spacing is best suited for connecting PV modules
installed in portrait orientation, while the 2.0 meter and 2.3 meters spacings allow you to install in landscape
orientation for PV modules with 54-cell/108-half-cell, 60-cell/120-half-cell, 66-cell/132-half-cell, 72-
cell/144-half-cell configurations.
