Commissioning and Operation
WARNING: Risk of electric shock. Risk of fire. Qualified personnel only may connect the
Enphase Microinverter to the electricity network.
WARNING: Risk of electric shock. Risk of fire. 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.
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.
Energise the 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 the Envoy to discover all of the microinverters varies with the number
of microinverters in the system and quality of the power line communications. At a typical
residential installation, all of the microinverters are detected within 15 minutes. Large
systems of 250 to 600 microinverters typically take one to two hours to detect all of the
microinverters.
4. If not done in Step 1, you may 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.
NOTE: If the Envoy has not been set up with a grid profile for the microinverters, the
microinverters may not produce energy. Most microinverters must be configured with the
appropriate grid profile as part of the commissioning process.
Check the Envoy's progress
Refer to the Envoy Communications Gateway Installation and Operation Manual at
http://www.enphase.com/support for details on the following steps.
1. An automatic device scan runs for eight hours after 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 displays Enable Device Scan.
2. Check that the Envoy LCD shows a complete device count after about 30 minutes.
3. Check power line communications as shown by the number of bars on the Envoy LCD.
• Press and hold the Envoy menu button (on the right side of the Envoy).
• Release the menu button when the LCD displays Enable Communication Check.
4. Use the Envoy menu button to stop the scan when all devices are detected:
• Press and hold the Envoy menu button (on the right side of the Envoy).
• Release the menu button when the LCD displays Disable Device Scan.
