Use the Envoy to Complete System Setup
Refer to the to the Envoy Quick Install Guide for
details on the following steps:
a. An automatic device scan runs for eight hours af-
ter the Envoy is installed. If this scan has expired,
start a new scan:
• Press and hold the Envoy menu button (on the
right side of the Envoy).
• Release the menu button when the LCD screen
displays Enable Device Scan.
b. Use the Envoy menu button
to select Enable Commu-
nication Check. Ensure at
least three level bars show
on the LCD.
c. When all devices are de-
tected, stop the scan. To do
this, use the Envoy menu

NOTE: Verify that AC voltage at the site is within range:
240 Volt AC Single-Phase
L1 to L2 211 to 264 VAC
L1, L2, to N 106 to 132 VAC
WARNING: Only use electrical system components approved
for wet locations.
WARNING: Do not exceed the maximum number of microin-
verters in an AC branch circuit as listed in the table below. Each
branch circuit must be protected by a dedicated circuit breaker
of 20 A or less.
Service type
240 VAC single-phase
208 VAC three-phase
WARNING: Size the AC wire gauge to account for voltage drop
for both the branch circuit and all upstream conductors lead-
ing back to the PCC. See Circuit Calculations for M215 at
http://www.enphase.com/support.

DANGER: ELECTRIC SHOCK HAZARD. THE DC
CONDUCTORS OF THIS PHOTOVOLTAIC SYSTEM ARE
UNGROUNDED AND MAY BE ENERGIZED.
WARNING: Allow a minimum of 1.9 cm (0.75") between the
roof and the microinverter. Also allow 1.3 cm (0.50") between
the back of the PV module and the top of the microinverter.
NOTE: Torque the microinverter fasteners to the values shown.
Do not over torque:
• 1/4" mounting hardware – 5 N m (45-50 in-lbs)
• 5/16" mounting hardware – 9 N m (80-85 in-lbs)
Using a power screwdriver is not recommended due to the risk
of thread galling.
NOTE: The AC output neutral is not bonded to ground inside
the microinverter.

WARNING: Install sealing caps on all unused AC connectors
as these become live when the system is
energized by the utility. The IP67-rated
sealing caps are required for
protection against moisture ingress.
NOTE: To remove a sealing cap, you
must use the Enphase disconnect tool or
a #3 Phillips screwdriver.
