Wire Management of AC and DC Cables Under Array
Since the Q Cable contains only two conductors, it is smaller and lighter than the previous generation
Engage Cable. For this reason, we use cable clips with a reduced wire retention area for the Q Cable. The
outer dimensions of the Q Cable allow it to be supported by many of the existing PV cable clips and USE-2
cable clips that are frequently used for supporting the DC module leads today.
Enphase has evaluated and developed wire clips for a wide variety of applications, including rail based
applications, rail-less applications, and AC Module applications. These clips are listed later in this section.
DC Cable Adapters for IQ Microinverters
The IQ 6 and IQ 6+ Microinverters ship with MultiContact MC4 DC connectors. You can
order Amphenol UTX DC connectors, if needed. Remove the DC connector assembly on
the microinverter and replace it using the Enphase Disconnect Tool for Q Cable
connectors (Q-DISC). This tool can disconnect both the AC and DC connectors on the
microinverter and disconnect MC4 and UTX connectors. When installing the AC Module
with Enphase IQ Microinverter, the Disconnect Tool also provides the means to release the
microinverter snaps to lower the microinverter into shipping position if needed.
Replacement adaptors are available for IQ Microinverters:
Q-DCC-2
IQ Microinverter Replacement Adaptor for MultiContact MC4 DC Connector
Q-DCC-5
IQ Microinverter Replacement Adaptor for Amphenol UTX DC Connector
Wire Management Clips for Attaching Q Cable to Solar Mounting
Rails
The Enphase Q Clip (Q-CLIP-100) can manage one or two Q Cables or raw Q Cables
to a solar mounting rail. This clip has been evaluated with a large selection of racking
systems and works with most available rail based racking systems. These clips support
the cable along the rail and may be adequate for supporting the cabling during row to
row transitions (depending on cable length), but additional support may be provided from module frame clips.
Use at least one clip or other support for every six feet of cable.
Wire Management Clips for Attaching Q Cable to Module Frames for Rail-less and
AC Module Applications
There are a variety of products available for supporting DC module leads off the roof. Most of the wire clips
available for PV cable and for USE-2 cable can also be used to attach Q Cable to module frames. Attaching
Q Cable to module frames can be useful for rail-less racking systems since there is no rail on which to
support the cabling. Also, for AC Module installations, it is often more convenient to clip the Q Cable to the
module frame than to clip the Q Cable to the racking system (if available).
