IQ 6/IQ 6+ Micro Installation and Operation 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.
IQ 6/IQ 6+ Micro Installation and Operation How the Enphase IQ 6 and IQ 6+ 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.
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.
IQ 6/IQ 6+ Micro Installation and Operation 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).
IQ 6/IQ 6+ Micro Installation and Operation 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.
IQ 6/IQ 6+ Micro Installation and Operation Parts and Tools Required In addition to the microinverters, PV modules, and racking, you will need the following: Enphase Equipment Enphase IQ Envoy communications gateway (ENV-IQ-AM1-240) required to monitor solar production. For installation information, refer to the Enphase IQ Envoy Installation and Operations Manual. Enphase Installer Toolkit Download the Enphase Installer Toolkit mobile app and open it to log in to your Enlighten account.
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.
IQ 6/IQ 6+ Micro Installation and Operation Step 1: Position the Enphase Q Cable A. Plan each cable segment to allow drop connectors on the Enphase Q Cable to align with each PV 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 along the installed racking for the AC branch circuit. D. Cut each segment of cable to meet your planned needs.
IQ 6/IQ 6+ Micro Installation and Operation Step 3: Mount the Microinverters A. Mount the microinverter bracket side up (as shown) and under the PV module, away from rain and sun. Allow a minimum of 1.9cm (3/4”) between the roof and the microinverter. Also allow 1.3 cm (1/2”) between the back of the PV module and the top of the microinverter. WARNING: Install the microinverter under the PV module to avoid direct exposure to rain, UV and other harmful weather events.
IQ 6/IQ 6+ Micro Installation and Operation Step 4: Create an Installation Map The Enphase Installation Map is a diagram of the physical location of each microinverter in your PV installation. Copy or use the blank map on page 52 to record microinverter placement for the system, or provide your own layout if you require a larger or more intricate installation map. Each Enphase Microinverter, Envoy, and Battery have a removable serial number label.
IQ 6/IQ 6+ Micro Installation and Operation Step 5: Manage the Cabling A. Use cable clips or tie wraps to attach the cable to the racking. Leave no more than 1.8 m (six feet) between cable clips or tie wraps. 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. WARNING: Tripping Hazard. Loose cables can become a tripping hazard. Dress the Enphase Q Cable to minimize this potential.
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. A. Remove 13 mm (½ inch) of the cable sheath from the conductors. Use the terminator loop to measure 13 mm. Terminator Body 13mm B. Slide the hex nut onto the cable. There is a grommet inside of the hex nut that should remain in place. C.
IQ 6/IQ 6+ Micro Installation and Operation D. Insert a screwdriver into the slot on top of the terminator to hold it in place, and use a 27 mm wrench or channel lock pliers to tighten the hex nut until the threads disappear. 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.
IQ 6/IQ 6+ Micro Installation and Operation Step 8: Complete Installation of Junction Box or an Enphase Q Aggregator 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. Refer to the wiring diagrams on page 54 for more information. Wire colors are listed in the following table.
IQ 6/IQ 6+ Micro Installation and Operation Step 10: Energize the System A. If applicable, turn ON the AC disconnect or circuit breaker for the branch circuit. B. Turn ON the main utility-grid AC circuit breaker. Your system starts producing power after a five-minute wait time. C. Check the LED on the connector side of the microinverter: LED color Indicates Flashing green Normal operation. AC grid function is normal there is communication with the IQ Envoy.
