Specifying Cabling and Accessories at
the Array
The Enphase IQ Microinverter system uses a new
and improved cabling system. The Q Cable is DG
type and contains only two #12 AWG line conductors.
The Q Cable male connectors plug directly into the
IQ Micros, whose double insulation rating requires no
neutral or ground conductors. This lightweight cable
drives down system costs while simplifying
installation.

Q Cable is a single-phase, two-line conductor cable with integrated AC connectors available in three
connector-spacing configurations for different PV module sizes and layouts. Three-phase system
configurations will be introduced in Fall 2017. We also offer a raw Q Cable without integrated AC connectors
for runs between separated arrays or to a junction box located some distance away from an array.
