Install Enphase IQ 7 Series Micros with Integrated MC4
Connectors
To install Enphase IQ™ Series Microinverters, read and follow all warnings and instructions in this guide and in the Enphase IQ Series Microinverter
Installation and Operation Manual at: enphase.com/support. Safety warnings are listed on the back page of this guide.
The Enphase Microinverter models listed in this guide do not require grounding electrode conductors (GEC), equipment grounding conductors (EGC), or
grounded conductor (neutral). The microinverter has a Class II double-insulated rating, which includes ground fault protection (GFP). To support GFP, use
only PV modules equipped with DC cables labeled PV Wire or PV Cable.
IMPORTANT: The Enphase IQ Series microinverters include both AC and DC connectors integrated into the bulkhead. The AC port connects to an Enphase
Q Cable or Enphase Field Wireable Connector. The DC port has been evaluated by UL for intermateability with Staubli made MC4 connectors, whose
cable coupler models are “PV-KST4/…-UR, PV-KBT4/…-UR, PV-KBT4-EVO2/…-UR, and PV-KST4-EVO2/…-UR”.
NOTE: Installer must check the manufacturing date of the products to ensure that the installation date is within one year of the manufactured date of
the products. Contact your local distributor to validate the date code.

*Allows for 30cm of cable slack
D ) Check that you have these other items:
• Enphase Q Aggregator or AC junction box.
• Tools: screwdrivers, wire cutter, voltmeter, torque wrench, sockets,
and wrenches for mounting hardware
E ) Protect your system with lightning and/or surge suppression devices. It
is also important to have insurance that protects against lightning and
electrical surges.
F ) Plan your AC branch circuits to meet the following limits for maximum
number of microinverters per branch when protected with a 20-amp
over-current protection device (OCPD).
Maximum* Number of IQ Micros per AC branch circuit - single phase
240V IQ 7 IQ 7+ IQ 7A
16 13 11
208V IQ 7 IQ 7+ IQ 7A
13 11 11
* Limits may vary. Refer to local requirements to dene the number of
microinverters per branch in your area.
G ) Size the AC wire gauge to account for voltage rise. Select the correct
wire size based on the distance from the beginning of the Enphase Q
Cable to the breaker in the load center. Design for a voltage rise total
of less than 2% for these sections. Refer to the Voltage Rise Technical
Brief at enphase.com/support for more information.
Best practice: Center-feed the branch circuit to minimize voltage rise in a
fully-populated branch. Using the Q Aggregator is a good way to do this.

and cautionary markings in the technical
description, on the Enphase Microinverter
System, and on the photovoltaic (PV)
equipment.
Microinverter Safety
+DANGER: Risk of electric shock. Risk of
re. Do not attempt to repair the Enphase
Microinverter; it contains no user-ser-
viceable parts. If it fails, contact Enphase
customer service to obtain an RMA (return
merchandise authorisation) number and
start the replacement process. Tampering
with or opening the Enphase Microinverter
will void the warranty.
+DANGER: Risk of re. The DC conductors of
the PV module must be labeled “PV Wire”
or “PV Cable” when paired with the Enphase
Microinverter.
*WARNING: You must match the DC
operating voltage range of the PV module
with the allowable input voltage range of the
Enphase Microinverter.
*WARNING: The maximum open circuit
voltage of the PV module must not exceed
the specied maximum input DC voltage of
the Enphase Microinverter.
*WARNING: Risk of equipment damage. In-
stall the microinverter under the PV module
to avoid direct exposure to rain, UV, and
other harmful weather events. Always install
the microinverter bracket side up. Do not
mount the microinverter upside down. Do
not expose the AC or DC connectors (on the
Enphase Q Cable connection, PV module, or
the microinverter) to rain or condensation
before mating the connectors.
*WARNING: Risk of equipment damage. The
Enphase Microinverter is not protected from
damage due to moisture trapped in cabling
systems. Never mate microinverters to
cables that have been left disconnected and
exposed to wet conditions. This voids the
Enphase warranty.
*WARNING: Risk of equipment damage. The

a standard, compatible PV module with
appropriate ll-factor, voltage, and current
ratings. Unsupported devices include smart
PV modules, fuel cells, wind or water turbines,
DC generators, and non-Enphase batteries, etc.
These devices do not behave like standard PV
modules, so operation and compliance is not
guaranteed. These devices may also damage
the Enphase Microinverter by exceeding its
electrical rating, making the system potentially
unsafe.
;WARNING: Risk of skin burn. The chassis
of the Enphase Microinverter is the heat
sink. Under normal operating conditions,
the temperature could be 20°C above
ambient, but under extreme conditions the
microinverter can reach a temperature of
90°C. To reduce risk of burns, use caution
when working with microinverters.
✓NOTE: The Enphase Microinverter has
eld-adjustable voltage and frequency trip

A ) Remove 13 mm (1/2”) of the cable sheath
from the conductors. Use the terminator
loop to measure.
B ) Slide the hex nut onto the cable. There is a
grommet inside of the terminator body that
should remain in place.
C ) Insert the cable into the terminator body so
that each of the two wires land on opposite
sides of the internal separator.
D ) Insert a screwdriver into the slot on the top of the terminator to hold it in
place, and torque the nut to 7 Nm.
E ) Hold the terminator body stationary with the screwdriver and turn only
the hex nut to prevent the conductors from twisting out of the separator.
F ) Attach the terminated cable end to the PV racking with a cable clip or
tie wrap so that the cable and terminator
do not touch the roof.
Connect the PV Modules
A ) Connect the DC leads of each PV module to the DC input connectors
of the microinverter.
B ) Check the LED on the connector side of the microinverter. The LED
ashes six times when DC power is applied.
C ) Mount the PV modules above the microinverters.
DANGER! Electric shock hazard. The DC conductors of
this PV system are ungrounded and may be energized.

WARNING: The terminator can
not be re-used. If you unscrew
the nut, you must discard the
terminator.

This product is UL Listed as PV Rapid Shut Down Equipment and conforms with
NEC-2014 and NEC-2017 section 690.12 and C22.1-2015 Rule 64-218 Rapid
Shutdown of PV Systems, for AC and DC conductors, when installed according to
the following requirements:
• Microinverters and all DC connections must be installed inside the array boundary.
Enphase further requires that the microinverters and DC connections be
installed under the PV module to avoid direct exposure to rain, UV, and other
harmful weather events.
• The array boundary is dened as 305 mm (1 ft.) from the array in all directions, or
1 m (3 ft.) from the point of entry inside a building.
This rapid shutdown system must be provided with an initiating device and (or with)
status indicator which must be installed in a location accessible to rst responders,
or be connected to an automatic system which initiates rapid shutdown upon the ac-
tivation of a system disconnect or activation of another type of emergency system.
The initiator shall be listed and identied as a disconnecting means that plainly
indicates whether it is in the “off” or “on” position. Examples are:
• Service disconnecting means
• PV system disconnecting means
• Readily accessible switch or circuit breaker
The handle position of a switch or circuit breaker is suitable for use as an indicator.
Refer to NEC or CSA C22.1-2015 for more information.
Additionally, in a prominent location near the initiator device, a placard or label must
be provided with a permanent marking including the following wording:
’PHOTOVOLTAIC SYSTEM EQUIPPED WITH RAPID SHUTDOWN’ The term
‘PHOTOVOLTAIC’ may be replaced with ‘PV.’
