INSTALLATION

1

Choose a location for the Envoy-S

A ) Find a spot near the main load center or PCC (point of common cou-

pling).

B ) Install the Envoy-S inside a non-metallic, NRTL Certied NEMA type 3R

(or better) enclosure with conduit attachment.

C ) Mount the Envoy horizontally using the included DIN rail.

2

Wire the Envoy-S for Power and Metering

The Envoy-S uses terminal blocks for power and metering connections. One solid-core current transformer (CT) is provided for revenue grade production
metering. Two optional split-core CTs can be used to provide consumption metering. You must create a protected route using conduit for the CT wires from the main
load center to the Envoy-S. If you need to extend the wires, refer to the Enphase Envoy-S Installation and Operation Manual at: http://www.enphase.com/support.

Note: Because of variance in load center design and main power feed, there may not always be enough space to install consumption metering CTs.

A ) Wire the Envoy-S for power

•

Use a 15 A maximum circuit breaker for the supply wir­ing.

•

Make sure supply wiring is 14 AWG copper rated at 75
degrees C or better

installing is not displayed on the System Overview screen, tap the [+]
next to the word “Envoys”. When the app displays the serial number of
the Envoy-S, tap it to add it to the system.

E ) Create the arrays and scan the serial numbers from the installation

map as instructed by the Installer Toolkit Operation Manual
at http://www.enphase.com/support.

F ) Tap the Connect button. This provisions the scanned microinverters on

the Envoy-S.

G ) When prompted, conrm the number of microinverters that you in-

stalled.

The Microinverter Communications LED lights solid green if all of the pro­visioned devices are communicating or solid amber if any devices are not
communicating.

Method B // Discover microinverters with Installer Toolkit

Use the Installer Toolkit mobile app to set the number of microinverters the
Envoy-S should search for on the power line.

A ) Connect to the Envoy-S with your mobile device as described in the

note on top of the next page.

B ) Launch Installer Toolkit and tap Connect to an Envoy.

C ) When prompted, enter the number of microinverters that you installed.

D ) When prompted to start a device scan, tap OK.

The Microinverter Communications LED ashes green while scanning. It

lights solid green when all of the microinverters you installed are communi­cating or solid amber if any devices are not communicating.

Note: Connecting to Envoy-S with a Mobile Device

The Envoy’s AP (Access Point) Wi-Fi network allows you to connect
your mobile device to the Envoy-S. The AP Mode LED lights solid
green when the network is available.

through, leave the type set to Net, If not change the type to Total.

•

Tap Enable Consumption Meter.

E ) Return to the Envoy Overview screen and verify the meter reading(s).

If you used Installer Toolkit to detect microinverters, the Power Production
LED lights solid green when all expected microinverters are producing
power. If you did not use Installer Toolkit, it lights solid green if all

communicating microinverters are producing power. It ashes green

when microinverters are upgrading. Check Installer Toolkit for production
status details. If the Power Production LED remains solid amber, see

Troubleshootingc.

Microinverter detection issues

•

Check the Installer Toolkit mobile app to see which microinverters are not
communicating.

•

Check that the circuit breaker(s) for the PV array are in the “ON” position.

•

Verify that the PV modules are connected to the microinverters.

•

Verify the PV module DC voltage is within the allowable range for the microinverter.

Power production issues

•

If none of the microinverters are producing power, there may be a grid or wiring
issue. First, verify that there is proper input voltage and frequency from the utility.
Next, check the breaker and wiring, starting at the load center.

•

If all of the non-productive microinverters are on the same branch, check the
breaker and wiring starting at the junction box for the affected branch.

•

If only one or scattered microinverters are not producing power, rst check to see

that the AC connectors are fully seated in the Engage Cable connectors. Next,
check that each module is providing the required startup voltage for the micro­inverter (22V). A PV module that is failing or that is undersized may not generate
enough power for AC conversion.

Internet connection issues

•

The WPS connection window may have timed out. Retry the connection steps.

•

Make sure that the broadband router is operational by checking that other devices
at the site can access the network.

•

Be aware that metal enclosures or obstructions impede wireless communication.

•

If you cannot see your router or access point in the list on the Envoy, or cannot
maintain a connection, it may be necessary to add a wireless repeater to extend
the network range.
