Install a Replacement Microinverter
A. When the replacement microinverter is available, verify that the AC branch circuit breaker is
de-energized.
B. Mount the microinverter bracket side up and under the PV module, away from rain and sun.
Allow a minimum of 1.9cm (0.75") between the roof and the microinverter. Also allow 1.3cm
(0.50") between the back of the PV module and the top of the microinverter
WARNING: Risk of equipment damage. Mount the microinverter under the PV
module.
•
Install the microinverter under the PV module to avoid direct exposure to rain, UV,
and other harmful weather events.
•
Always install the microinverter bracket side up.
•
Do not mount the microinverter upside down.
•
Do not expose the AC or DC connectors (on the Enphase Q Cable connection, PV
module, or the microinverter) to rain or condensation before the connectors are
mated.
C. Torque the mounting fasteners to the values shown. Do not over torque.
•
6 mm (1/4") 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
D. If you are using bonding hardware, the old bonding hardware should be discarded, and new
bonding hardware must be used when installing the replacement microinverter.
E. Connect the microinverter to the Q Cable connector. Listen for a click as connectors engage.
F. Connect the DC leads of each PV module to the DC input connector of the microinverter.
G. Re-mount the PV module above the microinverter.
H. Energize the AC branch circuit breaker, and verify operation of the replacement microinverter
by checking the Status LED on the connector side of the microinverter.
