Enphase Q Cable Planning and Ordering

The Enphase Q Cable is a continuous length of 12 AWG, double insulated, outdoor-rated cable with

integrated connectors for microinverters. These connectors are preinstalled along the Q 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.

Connector Spacing Options

Q 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.

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.
