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.
Cabling Options
Ordering options include:
CABLE MODEL CONNECTOR SPACING PV MODULE ORIENTATION CONNECTOR COUNT PER BOX
Q-12-10-240 1.3m (50”) Portrait 240
Q-12-17-240 2.0m (78”) Landscape (60-cell) 240
Q-12-20-200 2.3m (90”) Landscape (72-cell) 200
The Cabling System is exible enough to adapt to almost any solar design. To determine the cable type you need,
apply the following considerations:
y 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.
y To transition between cable types, install a eld wireable connector.
y 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.
