Wire Management of AC and DC Cables Under Array
Since the Q Cable contains only two conductors, it is much 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+ Micros ship with either MultiContact MC4 DC connectors or
Amphenol UTX DC connectors, depending on the part number ordered. You can remove
the DC connector assembly on the microinverter and replace it using the Disconnect tool
for Q Cable connectors (Q-DISC). You can use this tool to disconnect both the AC and DC
connectors on the microinverter and disconnect MC4 and UTX connectors. When the AC
Module with Enphase IQ Micro becomes available, the Disconnect tool also provides the
means to releases the microinverter install snaps to lower the inverter into shipping
orientation 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) allows you to manage one or two Q Cables or raw Q
Cables to a solar mounting rail. We have evaluated a large selection of racking systems
and have found that this clip works with about 90% of the racking systems available.
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 to support the
