IQ 6 / IQ 6+ Micro Installation and Operation Do not use Enphase equipment in a manner not specified by the manufacturer. Doing so may cause DANGER: Risk of death or injury to persons, or damage to equipment. electric shock.
When installing the Enphase Q Cable, secure any loose cable to minimize tripping hazard. When looping the Enphase Q Cable, do not form loops smaller than 4.75” (12 cm) in diameter. NOTES: Provide support for the Enphase Q-Cable every 1.8m (6 feet).
The Enphase IQ System The Enphase IQ System includes: • Enphase IQ 6 and/or IQ 6+ Micros The smart grid ready IQ6 and IQ6+ Micros convert the DC output of the PV module into grid-compliant AC power. • Enphase IQ Envoy™ (ENV-IQ-AM1-240) The Enphase IQ Envoy is a communication device that provides network access to the PV array.
PV module. System Monitoring Once you install the Enphase IQ Envoy 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.
IQ 6 / IQ 6+ Micro Installation and Operation Planning for Microinverter Installation The Enphase IQ 6 Micro is compatible with 60-cell PV modules, and the IQ 6+ Micro supports PV modules with 60 or 72 Cells. Both install quickly and easily. The microinverter housing is designed for...
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.
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 Installer Toolkit Download the Enphase Installer Toolkit mobile app and open it to log in to your Enlighten account. With this app, you can scan microinverter serial numbers and connect to the IQ Envoy to track system installation progress. To download, go to enphase.com/toolkit...
IQ 6 / IQ 6+ Micro Installation and Operation Enphase Microinverter Installation Installing the Enphase IQ 6 and IQ 6+ Micros involves several key steps. Each step listed here is detailed in the following pages. Step 1: Position the Enphase Q Cable...
208 V Single-Phase 183 to 229 VAC B. Install an Enphase Q Aggregator or junction box at a suitable location on the racking. See the Enphase Q Aggregator Quick Install Guide. C. Provide an AC connection from the Enphase Branch Aggregator back to the electricity network using equipment and practices as required by local jurisdictions.
Each Enphase Microinverter, Envoy, and Battery have a removable serial number label. Build the installation map by peeling the serial number labels from the microinverter mounting plates and placing the labels on the map. You will also place the Enphase IQ Envoy and IQ Battery serial number on the map after installation.
Step 6: Connect the Microinverters A. Connect the microinverter. Listen for a click as the connectors engage. B. Cover any unused connector 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.
IQ 6 / IQ 6+ Micro Installation and Operation Step 7: Terminate the Unused End of the Cable Terminate the unused end of the Enphase Q Cable as follows. 13mm Terminator Body A. Remove 13 mm (½ inch) of the cable sheath from the conductors.
Step 8: Complete Installation of Junction Box or an Enphase Q Aggregator A. Connect the Enphase Q Cable into the Enphase Q Aggregator. The Enphase Q Cable uses the following wiring color code. A ground lug is provided on the Q Aggregator for convenient module/rack/balance of system (BOS) grounding.
“DC Resistance Low – Power Off Condition” on page 22. 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: •...
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 Enphase Energy customer support at enphase.com/en-us/support/contact.
The app then indicates that a clear message was sent. Other Faults All other faults are reported to the Envoy. Refer to the Enphase IQ Envoy Installation and Operation Manual at enphase.com/support for troubleshooting procedures.
L1, L2 to ground 106 to 132 VAC E. Using an Enphase disconnect tool, disconnect the AC cable for the microinverter in question from the Enphase Q Cable. F. Verify that utility power is present at the microinverter by measuring line to line and line to ground at the Enphase Q Cable connector.
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.
• 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.
These parts are available from your Enphase distributor. Enphase Q Cable Planning and Ordering The Enphase Q Cable is a continuous length of 12 AWG, 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.
IQ 6 / IQ 6+ Micro Installation and Operation Enphase Q Cable Accessories The Enphase Q Cable is available with several accessory options for ease of installation, including: • Enphase Q Aggregator: (Q-BA-3-1P-60) Aggregates up to three fully populated 20A branch circuits and supports solar arrays of up to 11.5kWac with a single rooftop aggregator...
Technical Data Technical Considerations Be sure to apply the following when installing the Enphase IQ 6 and/or IQ 6+ Micro System: 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.
Grid Interconnection Details Both the Enphase IQ 6 and the IQ 6+ Microinverter are grid support interactive inverters. This type of inverter is also known as a Grid Support Utility Interactive Inverter (GSUII). The IQ 6 and IQ 6+ also comply with California Rule 21 - 2016 and Hawaii Rule 14H - 2017.
