MAINTENANCE
In order to maintain the optimum
output of the module, quality and
safety, please conduct periodic in-
spection or cleaning.
It is also recommended to inspect
the electrical and mechanical con-
nections annually.
If you need electrical or mechanical
inspection or maintenance, it is rec-
ommended to have a licensed au-
thorized professional carry out the
inspection or maintenance to avoid
the hazards of electric shock or inju-
ry.
ANTI-REFLECTION GLASS SUR-
FACE CLEANING
Light dirt that does not shield light
completely does not significantly
degrade power generation perfor-
mance, but if the module surface
becomes dirty, it may reduce output
power, malfunction or hotspot may
occur.
It is recommended to clean the sur-
face of the module with water and
a soft cloth or sponge.
When cleaning with neutral glass
detergent or weak alkaline glass
detergent, it is recommended to
start with smallest area and from
the edge of solar modules in order
to check no damage occurs to the
glass.
After that, clean surface of glass
with wet and clean cloth.
Recommended detergent: "Glass
Magiclean"
1)
or "Windex® Original"
2)
1)
Glass Magiclean is a trademark
of Kao Corporation.
2)
2) Windex® is a trademark of
SC Johnson & Son, Inc.
It is recommended to read carefully
the manuals of detergent and un-
derstand notes on usage and first-
aid treatment.
To remove persistent dirt, the mod-
ule can be washed with a micro-
fiber cloth and ethanol.
Never use abrasive detergent,
strong alkaline detergent, strong
acid detergent or a detergent which
forms a protective layer on the sur-
face of the glass to clean any part of
the module. The performance of a
solar modules may be reduced.
Please be very careful since the war-
ranty will not cover the damages
caused by detergents.
When cleaning the PV module,
please do not put detergent on
junction box or connector. If deter-
gents and chemical substances ad-
here, junction box and connector
may be deteriorated or damaged.
REPLACE ONLY MICROINVERT-
ER
If Enphase authorizes a replacement
only Microinverter, follow the steps
below 1)~13).
Do not damage the module back-
sheet or glass surface during re-
placement work.
Do not step on any module during
module replacement work.
Use appropriate protective equip-
ment such as protective gloves or
safety belt.
Refer to the installation manual or

1)
Turn off the AC branch circuit break-
er.
2)
Remove fixing clamps of the failure
module on mounting location.
3)
Disconnect the Enphase AC Q Cable
from Microinverter by inserting the
Enphase disconnect tool.
4)
Put the failure module on the
ground from the roof.
5)
Disconnect the DC connector from
Microinverter using Enphase discon-
nect tool.
6)

original mounting location.
11) Connect the AC Q Cable to the new
AC module.
12) Fix new module using mounting
clamps.
13) Energize the AC branch circuit
breaker, and verify operation of the
replacement Microinverter by check-
ing the Status LED on the connector
side of the Microinverter.
REPLACE ENTIRE MODULE
If Enphase authorizes a replacement
entire AC module, follow the steps
below 1)~9).
