Installation Manual

Step Details

NOTE: Verify that AC voltage at the site is within range:

240 Volt AC Single-Phase 208 Volt AC Three-Phase

L1 to L2 211 to 264 VAC L1 to L2 to L3 183 to 229 VAC

L1, L2, to N 106 to 132 VAC L1, L2, L3 to N 106 to 132 VAC

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 by a dedicated circuit breaker of 20 A or less.

Service type Max S230s

per branch

Max S280s

per branch

240 VAC single-phase 17 14

208 VAC balanced three-phase 24 21

WARNING: Size the AC wire gauge to account for voltage rise for both the branch circuit and all upstream conductors leading

back to the PCC. See the Technical Brief on Voltage Rise 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)

NOTE: The AC output neutral is not bonded to ground inside the microinverter.

NOTE: To remove a sealing cap or AC connector, you must use

the Enphase disconnect tool or a #3 Phillips screwdriver.

NOTE: Engage Cable uses the following wiring scheme.
