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
