K. Verify the PV module DC voltage is within the allowable range shown in “Specications” on page 39 of this
manual.
L. Following the steps in Remove and Replace a Microinverter, remove the PV panel from the roof, and swap out
the microinverter with one from a known good, adjacent AC module. If after checking Enlighten periodically (this
may take up to 30 minutes), the problem moves to the adjacent module, this indicates that the PV module isn’t
functioning correctly. If it stays in place, the problem is with the original microinverter. Contact Enphase Customer
Support for help in reading the microinverter data and for help in obtaining a replacement microinverter, if needed
M. Check the DC connections between the microinverter and the PV module. The connection may need to be
tightened or reseated. If the connection is worn or damaged, it may need replacement.
N. Verify with your utility that line frequency is within range.
O. If the problem persists, contact Customer Support at enphase.com/en-us/support/contact.
Remove and Replace a Microinverter
If problems remain after following the troubleshooting steps listed previously, contact Enphase at enphase.com/
en-us/support/contact. If Enphase authorizes a replacement, follow the steps below. To ensure the microinverter is
not disconnected from the PV modules under load, follow the disconnection steps in the order shown:
A. De-energize the AC branch circuit breaker.
B. Enphase AC connectors are tool-removable only. To disconnect the microinverter from the Enphase Q Cable,
insert the disconnect tool and remove the connector.
C. Remove the AC Module from the roof per manufacturer instructions.
D. Once on the ground, disconnect the PV module DC connector from the microinverter using the Enphase
disconnect tool.
E. Press each of the four clips to free the microinverter.
F. Snap new replacement microinverter into place.
G. Connect the PV Module DC connectors to the microinverter.
H. Scan the new serial number.
NOTE: The serial number of the replacement microinverter will different from the serial number on the AC
Module frame.
I. Bring the AC Module back onto the roof or other mounting location.
J. Connect the AC Module AC connector and DC Connector to the Q Cable.
K. 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.
