Commissioning and Operation

WARNING: Be aware that only qualified personnel must connect the Enphase Microinverter to
the electricity network.
WARNING: Ensure that all AC and DC wiring is correct. Ensure that none of the AC and DC
wires are pinched or damaged. Ensure that all AC junction boxes are properly closed.
NOTE: Obtain proper approval for the installation from the authorities having jurisdiction.
NOTE: The Status LED on the underside of each microinverter will blink green six times to
indicate normal start-up operation approximately two minutes after DC power is applied.
REMINDER: Enphase Microinverters will not begin exporting power until the Envoy
Communications Gateway is installed and has detected all of the microinverters at the site. In
addition, the grid profile must be configured and the Envoy must have propagated these
settings to the microinverters.
For instructions on installing the Envoy and configuring the grid profile, refer to the Envoy
Installation and Operation Manual at http://www.enphase.com/support/downloads.

Commission the System

To commission the Enphase Microinverter PV system:
1. Turn ON the AC disconnect or circuit breaker (such as an isolation switch) for each microinverter
AC branch circuit.
2. Turn ON the main AC switch.
3. The Enphase Microinverters will begin communicating over the power lines to the Envoy. The time
required for all microinverters to report to the Envoy will vary with the number of microinverters in
the system. The first units should be detected within 15 minutes. After that, the Envoy will detect
approximately four microinverters per minute.
4. You will need to configure the microinverters with the appropriate grid profile before they can
produce power. For instructions on this procedure, refer to the Envoy Installation and Operation
Manual at http://www.enphase.com/support/downloads.
NOTE: If the Envoy has not been set up with a grid profile for the microinverters, they will not
produce energy. The microinverters must be configured with the appropriate grid profile as part
of the commissioning process.

Operating Instructions

The Enphase Microinverter is powered on when sufficient DC voltage from the PV module is applied. The Status
LED of each microinverter will blink green six times to indicate normal start-up operation approximately two
minutes after DC power is applied. You may need to use a handheld mirror to view indicator lights on the
undersides of the microinverters.
