Enphase IQ8 Install and Operation Manual

IQ8 / IQ8+ / IQ8M / IQ8A / IQ8H Micro Installation and Operation

Step 2: Position the Junction Box

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

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

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

B. Install a 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.

Step 3: Mount the Microinverters

A. Mount the microinverter horizontally bracket side up or vertically

• Always place the microinverter under the PV module, protected from direct exposure to rain, sun, and

other harmful weather events. 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.

• For vertical mount, also maintain > 30 cm (12”) clearance from the edges of the PV module to protect the

microinverter from direct exposure to rain, UV, and other harmful weather events.

WARNING: Install the microinverter under the PV module to avoid direct exposure to rain, UV, and other

harmful weather events. Do not mount the microinverter upside down.

B. Torque the microinverter fasteners as follows. Do not over torque.

• 6 mm (¼”) mounting hardware: 5 N m (45 to 50 in-lbs.)

• 8 mm (5/16”) mounting hardware: 9 N m (80 to 85 in-lbs.)

• When using UL 2703 mounting hardware, use the manufacturer’s recommended torque value

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 46 to record microinverter placement for the system or provide your own layout if you

require a larger or more intricate installation map.
