Enphase IQ Cable Planning and Ordering
The Enphase 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
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
Cabling Options
Ordering options include:
The Cabling System is flexible enough to adapt to almost any solar design. To determine the cable type, you need,
apply the following considerations:
•
When mixing PV modules in both portrait and landscape orientation, you may need to transition
between cable types. See the preceding table for available cable types.
• To transition between cable types, install a Field Wireable connector pair
.
•
In situations where portrait modules are widely spaced, you may need to use landscape spaced
cables for the portrait-oriented PV modules and create loops of excess cable, if needed.
WARNING
: Do not form loops smaller than 12 cm (4.75”) in diameter
