2.2 THE ENPHASE IQ SYSTEM
The Enphase IQ System includes:
The smart grid ready microinverter converts the DC output of the
PV module into grid-compliant AC power.
• Enphase IQ Envoy™ (model ENV-IQ-AM1-240) communications
gateway or IQ Combiner (model X-IQ-AM1-240-2 or 240-3):
The Enphase IQ Envoy is a communication device that provides
network access to the PV array. The IQ Envoy collects produc-
tion and performance data from the Enphase IQ Microinverters
over on-site AC power lines and transmits the data to Enlighten
through an internet or cellular modem connection. The IQ Envoy
is capable of monitoring up to 600 Enphase IQ Microinverters
and up to 39 Enphase IQ Batteries. For details, refer to Enphase's
IQ Envoy Installation and Operations Manual.
• Enphase Enlighten™ web-based monitoring and management
software. Installers can use Enlighten Manager to view detailed
performance data, manage multiple PV systems, and remotely
resolve issues that might impact system performance. Find out
more at enphase.com/enlighten.
• Enphase Installer Toolkit™ mobile app for iOS and Android
devices. It allows installers to configure the system while onsite,
eliminating the need for a laptop and improving installation
efficiency. You can use the app to:
• Connect to the IQ Envoy over a wireless network for faster
system setup and verification
• View and email a summary report that confirms a successful
installation
• Scan device serial numbers and sync system information with
Enlighten monitoring software
• Enphase Field Wireable Connectors (Q-CONN-10F and Q-CONN-
10M)
Use Enphase Field Wireable Connectors with Enphase Q Cable
or field cable to:
• Easily connect Q Cable on the roof without complex wiring
• Use female connectors to make connections from any Q
Cable open connector
• Make a jumper to connect with a remote part of the array: Use
female to female for cable-to-cable connections
• Use a mated pair of connectors to splice two cut ends of cable
How the AC Module Works
The Enphase Microinverter maximizes energy production by using
a sophisticated Maximum Power Point Tracking (MPPT) algorithm.
Each Enphase Microinverter is individually connected to one PV
module on the array. This configuration enables an individual MPPT
to control each PV module, ensuring that maximum power available
from each PV module is exported to the utility grid regardless of
the performance of the other PV modules in the array.
While an individual PV module in the array may be affected by
shading, soiling, orientation, or PV module mismatch, each Enphase
Microinverter ensures top performance for its associated PV module.
System Monitoring
Once you install the Enphase IQ Envoy or Enphase IQ Combiner
and provide an internet connection through a broadband router
or modem, the Enphase IQ Microinverters automatically begin
reporting to Enlighten. Enlighten presents current and historical
system performance trends and informs you of PV system status.
Optimal Reliability
Microinverter systems are inherently more reliable than traditional
inverters. The distributed nature of a microinverter system ensures
that there is no single point of system failure in the PV system.
Enphase Microinverters are designed to operate at full power at
ambient temperatures as high as 150°F (65°C).
Ease of Design
PV systems using Enphase Microinverters are very simple to design
and install. You will not need string calculations or cumbersome
traditional inverters. Low voltage DC wires connect from the PV
module directly to the co-located microinverter, eliminating the risk
of personnel exposure to dangerously high DC voltage.

Installation Site
Note the following guidelines that apply to the installation site:
• Solar modules are not explosion-proof and are not suitable for
use in explosive environments.
ÄDo not operate solar modules near highly flammable gas and
vapors (e.g., gas tanks, gas stations).
ÄDo not install modules in enclosed spaces.
ÄDo not install modules in locations where they may be submerged
in water (e.g., floodplains).
ÄDo not use modules as a substitute for the normal roofing (e.g.,
modules are not watertight).
ÄDo not install modules in close proximity to air conditioning
systems.
ÄDo not install modules above 6,561ft (2,000 m) altitude above
sea level.
ÄContact with saline water (e.g., spray water from the sea) and
salt aggregation on the modules must be avoided.
ÄDo not bring any chemical substance (e.g., oil, solvent etc.) into
contact with any part of the panel. Only substances approved
by Q CELLS should be used during installation, operation, and
maintenance.
ÄAny installation of modules on surfaces of water is prohibited.
This includes installations on floating as well as pile-based
platforms. Q CELLS may extend the coverage of its warranty
to such installations, based on a case by case assessment of
the system design and location. A prior written consent by the
warrantor is required in any case.
Prevention of Shadowing Effects
Optimal solar irradiation leads to maximum energy output:
ÄFor this reason, install the modules so that they face the sun.
ÄAvoid shadowing (due to objects such as buildings, chimneys
or trees).
ÄAvoid partial shading (for example through overhead lines,
dirt, snow).
Limitations
The solar modules are designed for the following applications:
• Operating temperatures from –40°F to +185 °F.
• Pull loads and push loads according to chapter 2.3 (‘Test Load’
in accordance with IEC 61215 and ‘Design Load ×1.5’ in accor-
dance with UL 1703).
• Installation using a mounting structure for solar modules.
Mounting Structure Requirements
Requirements for the mounting structure:
• Conforms to the necessary structural requirements.
• Compliant with local snow and wind loads.
• Properly fastened to the ground, the roof, or the façade.

Installation Site
The microinverter housing is designed for outdoor installation and
complies with the NEMA 250, type 6 environmental enclosure
rating standard:
NOTE!
NEMA 6 Rating Definition:
Indoor or outdoor use primarily to provide a degree of protection
against hose-directed water, the entry of water during occasional
temporary submersion at a limited depth, and damage from external
ice formation
The Enphase Q Cable is available with connector spacing options
to accommodate installation of PV modules in portrait or landscape
orientation. For Enphase Q Cable ordering information, see “Enphase
Q Cable Planning and Ordering” on page 30.
Planning the Racking
Plan the racking position with the microinverter in mind. Ensure that the
racking does not interfere with the microinverter and its connectors.
Grounding Considerations
The Enphase Microinverter models listed in this guide do not require
grounding electrode conductors (GEC), equipment grounding con-
ductors (EGC), or grounded conductors (neutral). Your Authority
Having Jurisdiction (AHJ) may require you to bond the mounting
bracket to the racking. If so, use UL2703 hardware or star washers.
The microinverter itself has a Class II double-insulated rating, which
includes ground fault protection (GFP).
Branch Circuit Capacity
Plan your AC branch circuits to meet the following limits for maximum
number of microinverters per branch when protected with a 20 amp
(maximum) over current protection device (OCPD).
MAXIMUM* IQ 7+ MICROS
PER AC BRANCH CIRCUIT (240 VAC)
13
MAXIMUM* IQ 7+ MICROS
PER AC BRANCH CIRCUIT (208 VAC)
11
NOTE!
*Limits may vary. Refer to local requirements to define the number
of microinverters per branch in your area.
Utility Service Requirements
The Enphase IQ Microinverter for ACM work with a single-phase
service. Measure AC line voltages at the electrical utility connection
to confirm that it is within the ranges shown:
240 VOLT AC, SINGLE PHASE
L1 to L2 211 to 264 VAC
L1, L2 to ground 106 to 132 VAC
208 VOLT AC, SINGLE PHASE
L1 to L2 183 to 229 VAC
L1, L2 to ground 106 to 132 VAC
Wire Lengths and Voltage Rise
When planning the system, you must select the appropriate AC
conductor size to minimize voltage rise. Select the correct wire size
based on the distance from the beginning of the AC branch circuit
to the breaker in the load center. Enphase recommends a voltage
rise total of less than 2% for the sections from the AC branch circuit
to the breaker in the load center.
Enphase provides guidance about choosing wire size and maximum
conductor lengths in the Voltage Rise Technical Brief at enphase.com
/support. Refer to this brief for voltage rise values in Enphase Q
Cables and on how to calculate voltage rise in other wire sections
of the system.
Standard guidelines for voltage rise on feeder and AC branch circuit
conductors might not be sufficient for microinverter AC branch
circuits that contain the maximum allowable microinverters. This is
due to high inherent voltage rise on the AC branch circuit.
NOTE!
Best practice:
Center-feed the branch circuit to minimize voltage rise in a fully-pop-
ulated branch. This practice greatly reduces the voltage rise as
compared with an end-fed branch. To center-feed a branch, divide
the circuit into two sub-branch circuits protected by a single OCPD.
2 PLANNING
2.4 FOR MICROINVERTER PLANNING
Lightning and Surge Suppression
Enphase Microinverters have integral surge protection greater
than most traditional inverters. However, if the surge has sufficient
energy, the protection built into the microinverter can be exceeded,
and the equipment can be damaged. For this reason, Enphase
recommends that you protect your system with a lightning and/or
surge suppression device. In addition to having some level of surge
suppression, it is also important to have insurance that protects
against lightning and electrical surges. Enphase has tested the
following devices:
• Leviton 51110-SRG
• Schneider SquareD HEPD50
NOTE!
Protection against lightning and resulting voltage surge must be in
accordance with local standards.
Parts and Tools Required
In addition to the AC Modules, you will need the following:
Enphase Equipment
• Enphase IQ Envoy (model ENV-IQ-AM1-240) communications
gateway or IQ Combiner (model X-IQ-AM1-240-2 or 240-3):

ATTENTION
ÄThe loads in the table are related to the mechanical stability of the solar modules. The mechanical stability of the mounting system
including clamps has to be evaluated by the system supplier. The listed test load values for Q CELLS were determined with the
following clamp parameters: clamp width = 1.58in (40 mm) and clamp depth = 0.39 in (10 mm). The system installer is responsible
for the determination of location-specific load requirements.
ÄEnsure that the subconstruction does not touch the junction box and/or the microinverter (even under load). The clamps or inser-
tion profiles etc. must also not touch the glass (even under load).
ÄEnsure that the connection cables of the junction box and/ or the microinverter do not run between the laminate and the mounting
rails.
ÄA minimum support depth of 0.59 in (15 mm) is required on the back side of the module for IP1, IP2, CL2b, CL3 and CL4. The
minimum required support depth on the modules backside for CL5 is 0.39 in (10 mm) on long frame side and 0.59 in (15 mm) on
short frame side. For IP1 and IP2 the minimum support depth on the front side of the module should be 0.39in (10 mm).
ÄFor CL1a, CL2a, CL3 and CL4 with rails: Ensure that the module frame is fixed directly on the rail of the substructure (no spacer
allowed between the module and substructure).
ÄModule bends under load. Therefore, sharp objects (e.g., screws) must not be mounted near the module's backside.
ÄUse M8 corrosion-proof screws and washers (diameter ≥15.8 mm or ≥ 0.62 in) for FB1 and FB2 mounting. Mounting screws and
washers should have the same material properties.

Protective Grounding
In order to prevent electrical shock or fire, the frame of the module
as well as any non-current-carrying metal parts of the system must
be grounded. While this section provides some information about
grounding the Q CELLS frames and modules, reference should be
made to local statutes and regulations for specific requirements
on grounding. The U.S. National Electrical Code addresses these
issues in Article 250.
Proper grounding is achieved by bonding all exposed non-current-
carrying metal equipment to the appropriately sized equipment
grounding conductor (EGC) or racking system that can be used
for integrated grounding.
Q CELLS frames are protected from corrosion with an anodized
coating, which has to be penetrated in order to ensure proper
bonding. The different methods listed below are suggested methods
for an appropriate bond between the frame and the EGC or racking
system (that will have to be properly grounded). The method appro-
priate for any individual installation will depend on multiple factors.
• Dimensions shown are in inches.
0.177” (+0.008/-0)

Option A: Use of a Grounding Lug
A listed grounding lug can be bonded to the frame using the grounding
holes pre-drilled in the frame. These holes are marked with a ground
symbol, as shown below on the frame section drawing. To install the
grounding lug, follow the specified instructions of the manufacturer.
The grounding lug should be made of stainless steel or tin plated
metals such as aluminum to avoid corrosion.
The grounding lug should be attached to the frame grounding hole
using a stainless steel screw, toothed lock washer or KEPS nut (in
order to penetrate the anodized layer) and backing nut. Care should
be taken to avoid the use of grounding hardware of dissimilar metals,
which may lead to corrosion.

Step 1: Install a Junction Box
A. Verify that AC voltage at the site is within range.
Service Type and Voltage: L1-L2
240 V Split-Phase 211 to 264 VAC
208 V Single-Phase 183 to 229 VAC
B. Install a junction box at a suitable location on the racking.
C. Provide an AC connection from the junction box back to the electricity network using equipment
and practices as required by local jurisdictions.
Step 2: Position and Connect the Enphase Q Cable
A. Plan each cable segment to allow drop connectors on the Enphase Q Cable to align with each
AC Module. Allow extra length for slack, cable turns, and any obstructions.
B. Mark the approximate centers of each PV module on the PV racking.
C. Lay out the cabling loosely on the roof for the AC branch circuit. Make sure the cable is
positioned in a way that allows you to connect it to the microinverter.
D. Cut each segment of cable to meet your planned needs.
WARNING: Do not install the modules in a way that creates continuous tension on the Q
Cable. When transitioning between rows, secure the cable to the rail to prevent cable or
connector damage. Do not count on the connector to withstand tension.
E. Connect the Enphase
Q Cable into the AC
junction box. The Q
Cable uses the
following wiring color
code:
Black = L1
Red = L2

Step 3: Terminate the Unused End of the Cable
Place sealing caps on unused connectors and terminate the unused end of the Enphase Q Cable.
A. Cover any unused connectors with Enphase Sealing Caps. Listen for a click as the connectors
engage.
WARNING: Risk of electric shock. Risk of fire. Install sealing caps on all unused AC
connectors as these connectors become live when the system is energized. Sealing caps
are required for protection against moisture ingress.
NOTE: If you need to remove a sealing cap, you must use the Enphase Disconnect Tool.
See “Remove and Replace a Microinverter” on page 43.
B. Remove 13 mm (½ inch) of the cable sheath from the conductors. Use the terminator loop to
measure 13 mm.
C. Slide the hex nut onto the cable. The grommet inside of the hex nut should remain in place.
D. Insert the cable into the terminator body so that each of the two wires land on opposite sides of
the internal separator.
E. Insert a screwdriver into the slot on the top of the terminator to hold it in place and torque the nut
to 7 Nm.
F. Hold the terminator body stationary with the screwdriver and
turn only the hex nut to prevent conductors from twisting out
of the separator.
NOTE: Turn only the hex nut to prevent conductors
from twisting out of the separator.
G. 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.
WARNING: The terminator cannot be re-used. If
you unscrew the nut, you must discard the
terminator.

Step 4: Prepare the AC Modules
A. Before installing the AC module, the microinverters must be lifted from the shipping position. On
the ground, turn the AC Module so that the microinverter faces you. Using both hands, lift the
microinverter up. You will hear four clicks as the microinverter locks into the installation position.
Ensure the four latches are locked, and the microinverter is not tilted.
NOTE: If you need to move the module, you can return the microinverter to the shipping position using
the Enphase Disconnect Tool. Use the tool to depress the four locking mechanisms on each corner of the
microinverter to return it to the shipping position.
B. Installer has to scan the microinverter Serial Number using the
Enphase Installer Toolkit mobile app.
C. Position the AC Modules as planned on the rail.
The Microinverter is in the shipping position.
The Microinverter is lifted and ready for installation.
Make sure the microinverter is not tilted.
Use this end of the disconnect tool
to depress the locking mechanisms.

Step 5: Mount the ACMs
You can use clamps or module mounting holes to mount the modules on the installation or you can use
an embedded system. If using an alternative mounting solution, contact to be sure that is covered by
the warranty. Refer to the mounting options on pages 14 and 15 for more information.
A. Install the ACM with a clearance of at least 10 cm (4 in.) from the roof. Also, make sure that the
microinverter on the underside of the ACM is at least 1.9 cm (0.75 in.) away from the roof or
installation surface.
B. Do not place the ACMs in such a way that places pressure on the microinverter. Minimum
distance from the top edge of the module to the rail should be about 270 mm (11.02 in.).
C. Make sure that the minimum gap between modules is 10 mm (0.4 in.) or greater.
D. Check that rails and clamps are clear of the microinverter by at least 3.8 cm (1.5 in.). Do not
obstruct module drain holes.
Step 6: Connect the Microinverters as you Install the ACMs
A. Check again that the ACMs are not placing pressure on the microinverter. Minimum distance from
the top edge of the module to the rail should be about 30 cm (12 in.).
B. As you install each ACM, connect the Q Cable to the microinverter. Listen for a click as the
connectors engage.
C. Cover any unused connectors on the AC cable with Enphase Sealing Caps. Listen for a click as
the sealing caps engage.
WARNING: Risk of electric shock. Risk of fire. Install sealing caps on all unused AC
connectors as these connectors become live when the system is energized. Sealing caps
are required for protection against moisture ingress.
Step 7: Manage the Cabling
A. Use cable clips to attach the cable to the module frame. Leave no more than 1.8 m (six feet)
between cable clips.
Cable clip
B. Dress any excess cabling in loops so that it does not contact the roof. Do not form loops smaller
than 12 cm (4¾ “) in diameter.

Step 8. Ground the ACMs
Choose to use grounding clamps or module mounting holes to ground the modules. Or, you can use a
reliable third-party grounding system.
All Methods:
A. Ground the module frames to protect the array from lightning and static-electricity damage using
Method A, B, or C.
B. Be sure that the grounding device will fully contact the inner side of the aluminum alloy and
penetrate the frame surface oxide film.
C. Make a connection from the grounding conductor to earth using a suitable earth ground
electrode.
WARNING: Risk of equipment damage. Do not drill additional grounding holes on module
frame. The module frame has been drilled and marked for grounding. Use the Grounding
holes only for grounding, and do not used them for mounting or other purposes.
NOTE: The grounding conductor or strap can be copper, copper alloy, or any other
material acceptable for use as an electrical conductor per the National Electrical Codes.
The grounding wire material and size must meet all local and regional requirements.
Method A: Grounding with grounding clamps.
Locate the grounding hole (diameter Ø4 mm) at the edge of the module frame back.
Use 12 AWG copper core wire for the grounding clamp, and do not damaged the copper wire
during installation.
Torque to 2.3N•m.
Method B: Grounding with unused mounting holes.
You can use the frame edge grounding holes or unused
mounting holes on the ACM for installing grounding
devices.
Align a grounding clamp to the frame hole
and place a grounding bolt through the
grounding clamp and frame.
Place the toothed side of the washer as
shown and fasten the nuts.
Place the grounding wire through the
grounding clamp and tighten the nuts.
Method C: Grounding with third party hardware.
You can use third party grounding devices for grounding of solar modules, but these devices must be
reliable and must be operated per manufacturer instructions.

Step 10: Set Up and Activate Monitoring
Refer to the Enphase IQ Envoy Quick Install Guide to install the IQ Envoy and set up system monitoring
and grid management functions. This guide leads you through the following:
Connecting the IQ Envoy
Detecting devices and scanning the installation map
Connecting to Enlighten
Registering the system
Building the virtual array
NOTE: When the utility requires a profile other than the default IEEE 1547 (for example
grids managed by Hawaii Electric Industries [HEI] including HECO) you must select an
appropriate grid profile for your installation. You can set the grid profile through
Enlighten, during system registration, or through Installer Toolkit at any time. You must have
an Enphase Envoy communications gateway to set or change the grid profile. For more
information on setting or changing the grid profile, refer to the Enphase IQ Envoy Installation
and Operation Manual at enphase.com/support.
