IQ 7 / IQ 7+ / IQ 7X / IQ 7A 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.

WARNING: When transitioning between rows, secure the cable to the rail to prevent cable

damage or connector damage. Do not count on connector to withstand tension.

Step 2: Position the Enphase Q Aggregator or Junction Box

A. Verify that AC voltage at the site is within range.

Service Type and Voltage: L1-L2

240 VAC Split-Phase

211 to 264 VAC

208 VAC Single-Phase

183 to 229 VAC

NOTE: All 208 VAC installations require that you use the Enphase IQ Envoy to commission

the Enphase Microinverters to propagate correct grid profile settings for 208 VAC trip points.

B. Install an Enphase Q Aggregator or 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.
