This manual describes the safe installation and operation of the Enphase Microinverter.

Enphase IQ 7X - The Enphase IQ System - 1

NOTE: To ensure optimal reliability and to meet warranty requirements, the Enphase Microinverter must be installed according to the instructions in this manual.

How the Enphase IQ Series Micros Work

The Enphase Microinverter maximizes energy production by using a sophisticated Maximum Power Point Tracking (MPPT) algorithm. Each Enphase Microinverter individually connects to one PV module in your 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 Envoy-S 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 65°C (150°F).

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. You can install individual PV modules in any combination of PV module quantity, type, age and orientation. Each microinverter quickly mounts on the PV racking, directly beneath each PV module. 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.

Planning for Microinverter Installation

The Enphase IQ 7 Micro is compatible with 60-cell PV modules, and the IQ 7+ Micro supports PV modules with 60 or 72 Cells. The IQ 7X requires a 96-cell PV module. All of them install quickly and easily. The microinverter housing is designed for outdoor installation and complies with the IP67 environmental enclosure rating standard:

Enphase IQ 7X - Planning for Microinverter Installation - 1

IP67 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 in multiple connector spacing options for landscape and portrait orientations in 60 and 72-cell PV modules to meet varying site requirements. For Enphase Q Cable ordering information, see “Enphase Q Cable Planning and Ordering” on page 27.

Compatibility

The Enphase IQ Series Micros are electrically compatible with PV modules as listed in the following table. For specifications, see “Technical Data” on page 28 of this manual. You can refer to the Enphase Compatibility Calculator at: module-compatibility to verify PV module electrical compatibility. To ensure mechanical compatibility, be sure to order the correct connector type for both microinverter and PV module from your distributor.

Enphase IQ 7X - Compatibility - 1

WARNING: Risk of fire. The PV module DC conductors must be labeled "PV Wire" or "PV Cable" to comply with NEC for Ungrounded PV Power Systems.

Enphase IQ 7X - Compatibility - 2

NOTE: Some Enphase Microinverters will not begin exporting power until the Envoy is installed and has detected all of the microinverters at the site. In addition, the grid profile may need to be configured and the Envoy must have propagated these settings to the microinverters. For instructions on this procedure, refer to the Envoy Installation and Operation Manual at enphase.com/support.

Grounding Considerations

The IQ Series Micros do not require grounding electrode conductors (GEC) or equipment grounding conductors (EGC). Your Authority Having Jurisdiction (AHJ) may require you to bond the mounting bracket to the racking. If so, use earthing hardware or star washers. The microinverter itself 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.

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 over-current protection device (OCPD). For multiphase installations, use a 3-pole 20A OCPD.

Maximum* IQ Micros per AC branch circuit

Single-phase161312
Multiphase483936

Enphase IQ 7X - Branch Circuit Capacity - 1

NOTE: *Limits may vary. Refer to local requirements to define the number of microinverters per branch in your area

Utility Service Requirements

The Enphase Microinverter works with single-phase 230 VAC service. Measure AC line voltage at the electrical utility connection to confirm that it is within the ranges shown:

Single-Phase ServiceThree-Phase Service
L1 to N207 to 253 VACL1 to L2 to L3360 to 440 VAC
L1, L2, L3 to N207 to 253 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 microinverter 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 microinverter 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.

Enphase IQ 7X - Wire Lengths and Voltage Rise - 1

Best practice: Center-feed the branch circuit to minimize voltage rise in a fully-populated 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.

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 IQ 7X - Lightning and Surge Suppression - 1

NOTE: Protection against lightning and resulting voltage surge must be in accordance with local standards.

B. Refer to the wiring diagrams on page 38 for more information. Q Cable uses the following color code:

Single-PhaseThree-Phase
Brown – L1Blue – NBrown – L1Black – L2Grey – L3Blue – N

Enphase IQ 7X - Step 8: Complete Installation of the Junction Box - 1

NOTE: The Q Cable internally rotates L1, L2, and L3 to provide balanced 400 VAC (three-phase), thus alternating phases between microinverters.

NOTE: Minimise the number of unused Q Cable connectors with three-phase systems. When cable connectors are left unused on a three-phase system, it creates a phase imbalance on the branch circuit. If multiple cable connectors are skipped over multiple branch circuits, the imbalance can multiply.

Step 9: Connect the PV Modules

Enphase IQ 7X - Set Up and Activate Monitoring - 1

NOTE: When the utility requires a profile other than the profile resident on the microinverter, 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 to set or change the grid profile. For more information on setting or changing the grid profile, refer to the Enphase Envoy-S Installation and Operation Manual at enphase.com/support.

Troubleshooting

Follow all the safety measures described throughout this manual. Qualified personnel can use the following troubleshooting steps if the PV system does not operate correctly.

Enphase IQ 7X - Troubleshooting - 1

WARNING: Risk of electric shock. Do not attempt to repair the Enphase Microinverter; it contains no user-serviceable parts. If it fails, contact Enphase customer service to obtain an RMA (return merchandise authorization) number and start the replacement process.

Status LED Indications and Error Reporting

The following section describes LED indications.

LED Operation

LED colorIndicates
Flashing greenNormal operation. AC grid function is normal there is communication with the Envoy-S.
Flashing orangeThe AC grid is normal but there is no communication with the Envoy-S.
Flashing redThe AC grid is either not present or not within specification.
Solid redThere is an active “DC Resistance Low, Power Off Condition.” To reset, see “DC Resistance Low – Power Off Condition” on page 21.

The status LED on each microinverter lights green about six seconds after DC power is applied. It remains lit solid for two minutes, followed by six green blinks. After that, red blinks indicate that no grid is present if the system is not yet energized.

Any short red blinks after DC power is first applied to the microinverter indicate a failure during microinverter startup.

DC Resistance Low – Power Off Condition

For all IQ Series models, a solid red status LED when DC power has been cycled indicates the microinverter has detected a DC Resistance Low – Power Off event. The LED will remain red and the fault will continue to be reported by the Envoy until the error has been cleared.

An insulation resistance (IR) sensor in the microinverter measures the resistance between the positive and negative PV inputs to ground. If either resistance drops below a threshold, the microinverter stops power production and raises this condition. This may indicate defective module insulation, defective wiring or connectors, moisture ingress, or a similar problem. Although the cause may be temporary, this microinverter condition persists until the sensor is manually reset.

An Envoy-S is required to clear this condition. The condition clears on operator command unless its cause is still present.

If a microinverter registers a “DC Resistance Low - Power Off” condition, you can attempt to clear this condition. If the condition does not clear after you perform the following procedure, contact Customer Support at https://enphase.com/en-us/support/global-contact.

There are two ways to send a clear message to the microinverter. Note that the condition will not clear after sensor reset if the cause of the failure is still present. If the condition persists, contact your installer or Enphase for possible replacement.

Method 1: Clear this Error Using Enlighten

  • Log in to Enlighten and access the system.
  • Click the Events tab. The next screen shows a current "DC Resistance Low - Power Off" condition for the system.
  • Click DC Resistance Low - Power Off.
  • Where "n" is the number of affected devices, click n devices (show details).
  • Click the serial number of the affected microinverter.
  • Click Reset DC Resistance Low - Power Off Sensor.

The system displays, "A DC Resistance Low- Power Off reset task was issued on [date and time] for this microinverter and is still pending."

Method 2: Use Installer Toolkit to Clear the Condition

On the list of detected microinverters, a green dot or red square appears to the left of each microinverter serial number. A green dot indicates Status OK. A red square indicates an event for that microinverter.

  • Tap the to the left of the serial number to view details for a microinverter event.
  • If the microinverter status shows that there is an active DC Resistance Low – Power Off condition, tap the to send the clear message to the affected microinverter. The app then indicates that a clear message was sent.

Troubleshoot an Inoperable Microinverter

To troubleshoot an inoperable microinverter, follow the steps in the order shown.

Enphase IQ 7X - Troubleshoot an Inoperable Microinverter - 1

WARNING: Risk of electric shock. Always de-energize the AC branch circuit before servicing. Never disconnect the DC connectors under load.

Enphase IQ 7X - Troubleshoot an Inoperable Microinverter - 2

WARNING: The Enphase Microinverters are powered by DC power from the PV modules. Make sure you disconnect the DC connections and reconnect DC power and then watch for the solid green about six seconds after connection to DC power.

A. Make sure AC breakers and disconnects are closed.
B. Check the connection to the utility grid and verify that the utility voltage is within allowable ranges.
C. Verify that AC line voltages at all solar power circuit breakers at the load center and subpanels are within the ranges shown in the following table.
D. Verify that AC line voltage at the junction box for each AC branch circuit at the site is within range:

Service Type and Voltage: L to N
230 V Single-Phase207 to 253 VAC

D. Using an Enphase disconnect tool, disconnect the AC cable for the microinverter in question from the Enphase Q Cable.

E. Verify that utility power is present at the microinverter by measuring line to line and line to ground at the Enphase Q Cable connector.

F. Visually check that the AC branch circuit connections (Enphase Q Cable and AC connections) are properly seated. Reseat if necessary. Check also for damage, such as rodent damage.

G. Make sure that any upstream AC disconnects, as well as the dedicated circuit breakers for each AC branch circuit, are functioning properly and are closed.

H. Disconnect and re-connect the DC PV module connectors. The status LED of each microinverter will light solid green a few seconds after connection to DC power and then blink green six times to indicate normal start-up operation about two minutes after connecting to DC power. The LED subsequently resumes normal operation if the grid is present. See page 21 for normal LED operation.

I. Attach an ammeter clamp to one conductor of the DC cables from the PV module to measure microinverter current. This will be under one amp if AC is disconnected.

J. Verify the PV module DC voltage is within the allowable range shown in "Specifications" on page 29 of this manual.

K. Swap DC leads with a known good, adjacent PV module. If after checking Enlighten periodically (this may take up to 30 minutes), the problem moves to the adjacent module, this indicates that the PV module isn't functioning correctly. If it stays in place, the problem is with the original microinverter. Contact Enphase Customer Support for help in reading the microinverter data and for help in obtaining a replacement microinverter, if needed.

L. Check the DC connections between the microinverter and the PV module. The connection may need to be tightened or reseated. If the connection is worn or damaged, it may need replacement.

M. Verify with your utility that line frequency is within range.

N. If the problem persists, contact Customer Support at https://enphase.com/en-us/support/global-contact.

Disconnect a Microinverter

If problems remain after following the troubleshooting steps listed previously, contact Customer Support at https://enphase.com/en-us/support/global-contact.

If Enphase authorizes a replacement, follow the steps below. To ensure the microinverter is not disconnected from the PV modules under load, follow the disconnection steps in the order shown:

A. De-energize the AC branch circuit breaker.
B. Enphase AC connectors are tool-removable only. To disconnect the microinverter from the Enphase Q Cable, insert the disconnect tool and remove the connector.
C. Cover the PV module with an opaque cover.
D. Using a clamp-on meter, verify there is no current flowing in the DC wires between the PV module and the microinverter. If current is still flowing, check that you have completed steps one and two above.

Enphase IQ 7X - Disconnect a Microinverter - 1

NOTE: Take care when measuring DC current as most clamp-on meters must be zeroed first and tend to drift with time.

E. Disconnect the PV module DC wire connectors from the microinverter using the Enphase disconnect tool.
F. If present, loosen and/or remove any bonding hardware.
G. Remove the microinverter from the PV racking.

Enphase IQ 7X - Disconnect a Microinverter - 2

WARNING: Risk of electric shock. Risk of fire. Do not leave any connectors on the PV system disconnected for an extended period. If you do not plan to replace the microinverter immediately, you must cover any unused connector with a sealing cap.

Install a Replacement Microinverter

A. When the replacement microinverter is available, verify that the AC branch circuit breaker is de-energized.
B. Mount the microinverter bracket side up and under the PV module, away from rain and sun. Allow a minimum of 1.9cm between the roof and the microinverter. Also allow 1.3cm between the back of the PV module and the top of the microinverter

Enphase IQ 7X - Install a Replacement Microinverter - 1

WARNING: Risk of equipment damage. Mount the microinverter under the PV module.

  • Install 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 the connectors are mated.

C. Torque the mounting fasteners to the values shown. Do not over torque.

  • 6 mm mounting hardware: 5 N m
  • 8 mm mounting hardware: 9 N m
  • When using earthing mounting hardware, use the manufacturer's recommended torque value

D. If you are using bonding hardware, the old bonding hardware should be discarded, and new bonding hardware must be used when installing the replacement microinverter.
E. Connect the microinverter to the Q Cable connector. Listen for a click as connectors engage.
F. Connect the DC leads of each PV module to the DC input connector of the microinverter.
G. Re-mount the PV module above the microinverter.
H. Energize the AC branch circuit breaker and verify operation of the replacement microinverter by checking the Status LED on the connector side of the microinverter.

I. Use the Installer Toolkit mobile app to delete the old microinverter serial number from the Enphase Envoy-S database. In Installer Toolkit, once connected to the Envoy:

a. Tap Micros > Manage.
b. Tap the checkbox to the right of the microinverter serial number replaced.
c. Tap to delete the microinverter from the Envoy-S database.

J. Add the new microinverter serial number to the Envoy database by initiating a device scan using one of the following methods:

a. Method 1: Initiate a scan using the Installer Toolkit mobile app

  • In Installer Toolkit, once connected to the Envoy-S, navigate to the Overview screen.
  • From the Overview screen, tap Detected > Start Device Scan to start a new 30-minute device scan.
  • If device scanning on the Envoy-S is inhibited, the app displays Scan Inhibited. If you need to add more microinverters to the system when device scanning is inhibited on the Envoy-S, you must use the Installer Toolkit scanning tool to provision them on the Envoy-S, rather than using the Envoy-S's device scanning function to discover them. If this is not possible and you need to enable device scanning on the Envoy-S, contact Customer Support at https://enphase.com/en-us/support/global-contact.

b. Method 2: Use an Envoy-S

- Press the Device Scan button on the Envoy-S. The Envoy-S begins a 15-minute scan to identify all of the microinverters deployed at the site. The Microinverter Communications LED flashes green during the scan.

K. Log in to Enlighten to use Enlighten's Array Builder to add the newly detected microinverter to the virtual array.

L. Ship the old microinverter to Enphase using the supplied return-shipping label.

Ordering Replacement Parts

Replacement adaptors for the Microinverter include:

• Q-DCC-2: Cable Assembly, DC adaptor to MC-4
• Q-DCC-5: Cable Assembly, DC adaptor to Amphenol UTX

These parts are available from your Enphase distributor.

Enphase Q Cable Planning and Ordering

The Enphase Q Cable is a continuous length of double insulated, outdoor-rated cable with integrated connectors for microinverters. These connectors are preinstalled along the Q Cable at intervals to accommodate varying PV module widths. The microinverters plug directly into the cable connectors.

The cabling is compatible with a variety of PV racking systems. For a list of approved PV racking systems, refer to the PV Racking Compatibility document on the Enphase website at enphase.com/support.

Connector Spacing Options

Q 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 spacing allows you to install 60-cell and 72-cell PV modules in landscape orientation, respectively.

Cabling Options

Ordering options include:

Cable ModelConnector spacingPV module orientationConnector count per box
Q-25-10-2401.3mPortrait240
Q-25-17-2402.0mLandscape (60-cell)240
Q-25-20-2002.3mLandscape (72-cell)200

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 available cable types.
    • To transition between cable types, install a 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.

Enphase IQ 7X - Cabling Options - 1

WARNING: Do not form loops smaller than 12 cm (4.75") in diameter.

Enphase Q Cable Accessories

The Enphase Q Cable is available with several accessory options for ease of installation, including:

  • Raw Q Cable: (Q-25-RAW-300) Length 300 meters. Raw cable with no connectors.
  • Field Wireable connectors (male): (Q-CONN-R-10M) Make connections from any open female Q connector or Field Wireable female connector
  • Field Wireable connectors (female): (Q-CONN-R-10F) Make connections from any Q Cable open connector or Field Wireable male connector
  • Cable clips: (E-CLIP-100) Used to fasten cabling to the racking or to secure looped cabling
  • Disconnect Tool: (Q-DISC-10) Disconnect tool for Q Cable connectors, DC connectors, and AC module mount
  • Q Cable sealing caps (female): (Q-SEAL-10) One needed to cover each unused connector on the cabling
    • Terminator: (Q-TERM-R-10) Terminator cap for cut cable ends

Technical Data

Technical Considerations

Be sure to apply the following when installing the Enphase IQ-Series Micro System:

Enphase IQ 7X - Technical Considerations - 1

WARNING: Risk of equipment damage. You must match the DC operating voltage range of the PV module with the allowable input voltage range of the Enphase Microinverter.

Enphase IQ 7X - Technical Considerations - 2

WARNING: Risk of equipment damage. The maximum open circuit voltage of the PV module must not exceed the specified maximum input voltage of the Enphase Microinverter.

  • PV modules must have conductors labeled "PV Wire" or "PV Cable" to comply with NEC for Ungrounded PV Power Systems.
  • Verify that the voltage and current specifications of the PV module match those of the microinverter.
  • The maximum short circuit current rating of the PV module must be equal to or less than the maximum input DC short circuit current rating of the microinverter.

The output voltage and current of the PV module depends on the quantity, size and temperature of the PV cells, as well as the insolation on each cell. The highest PV module output voltage occurs when the temperature of the cells is the lowest and the PV module is at open circuit (not operating).

Compliance Data
