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
NOTES
: 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.
The IQ7A microinverter has the same power rating at 208V L1-L2 as the IQ7+.
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.
