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 1.9 cm (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-lb)
•
8 mm (5/16") mounting hardware: 9 N m (80 to 85 in-lb)
•
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
the system, or provide your own layout if you require a larger or more intricate installation map.
Each Enphase microinverter and IQ Gateway has 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 must also place the IQ Gateway serial number on the map after
installation.
