IQ Cable planning and ordering

The IQ Cable is a continuous length of double-insulated, outdoor-rated cable with integrated connectors for
microinverters. These connectors are preinstalled along the IQ Cable at intervals to accommodate varying
PV module widths. The microinverters plug directly into the cable connectors.
The IQ Cable is compatible with many PV racking systems. For a list of approved PV racking systems, see the
PV Racking Compatibility document on the Enphase website at enphase.com/support.

Connector spacing options

IQ 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 spacings allow you to install 60-cell and
72-cell PV modules in landscape orientation, respectively.

Cabling options

Ordering options include:
Cable model
Q-25-10-240/Q-25-10-240-A*
Q-25-17-240/Q-25-17-240-A*
Q-25-20-200 Q-25-20-200-A*
* Models with "-A" designation for use only in Australia and New Zealand.
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 the available cable types.
• To transition between cable types, install an IQ 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.

Grid interconnection details

Enphase IQ7 Series Microinverters are grid support interactive inverters.

Grid profiles

IQ7 Series Microinverters have field-adjustable voltage and frequency trip points. Trip points are the input
voltage and frequency values that trigger the microinverters to shut down when the values are exceeded. If
local regulations require adjustments to these trip points, or if the grid profile was not set up during
registration, the installer can set up the system to use an alternate grid profile (set of trip points).
