a. Mount the PV modules above the
microinverters.
b. Connect the DC leads of each PV module to
the DC input connectors of the
corresponding microinverter.

WARNING: Perform all electrical installations in accordance with all
applicable local electrical standards.
WARNING: Only use electrical system components approved for
wet locations.
WARNING: Do NOT exceed the maximum number of microinverters
in an AC branch circuit as listed in the table below. Each branch
circuit must be protected with a 20A maximum breaker.
Service type
Single-Phase Service
Three-Phase Service
WARNING: Size the AC cable/wire size to account for voltage drop.
Select conductor diameter based on the distance from the beginning
of the microinverter AC branch circuit to the breaker in the AC mains.
See Voltage Drop Calculations at http://www.enphase.com.

WARNING: Allow a minimum of 1.9cm between the roof and the
bottom of the microinverter. Also allow 1.3cm between the back of
the PV module and the top of the microinverter.
NOTE: The AC output neutral is not bonded to earth inside
the microinverter.
NOTE: Torque the microinverter fasteners to these values:
• 6mm mounting hardware – 5 N m minimum
• 8mm mounting hardware – 9 N m minimum
• 10/32 earthing cleat screw – 2 N m minimum
Using a power screwdriver is not recommended due to the
risk of thread galling.

WARNING: Install sealing caps
on all unused AC connectors as
they become live when the system
is energised. IP67-rated sealing
caps are required to protect
against moisture ingress.
NOTE: To remove a sealing cap, you must use the Enphase
disconnect tool or a screwdriver.
