for help in obtaining a replacement microinverter, if needed.
L. 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.
M. Verify with your utility that the line frequency is within range.
N. If the problem persists, contact Enphase Support at

these steps. 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. AC connectors are tool-removable only. To disconnect the microinverter from the IQ Cable,
insert the disconnect tool and remove the connector.
C. Cover the PV module with an opaque cover.
D. Using a clamp-on meter, verify there is no current flowing in the DC wires between the PV
module and the microinverter. If the current is still flowing, check that you have completed
steps A and B above.
NOTE: Take care when measuring DC current, as most clamp-on meters must be zeroed
first and tend to drift with time.
E. Disconnect the PV module DC wire connectors from the microinverter using the
IQ Disconnect Tool.
F. If present, loosen and/or remove any bonding hardware.
G. Remove the microinverter from the PV racking.
WARNING: Risk of electric shock. Risk of fire. Do not leave any connectors on the PV
system disconnected for an extended period. If you do not plan to replace the
microinverter immediately, you must cover any unused connector with an IQ Sealing Cap.
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 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.
