5. Detect the Microinverters
Use one of the following methods to detect microinverters.
Method A: Provision Microinverters with Installer Toolkit
Use the Installer Toolkit mobile app to configure the Envoy-S with the serial numbers of the installed
microinverters.
a. Launch Installer Toolkit and tap View Systems.
b. Select the system you are working with, or tap [+] to add a system.
c. Connect to the Envoy-S with your mobile device as described in the side note.
d. Return to Installer Toolkit. If the serial number for the Envoy-S you are 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 enphase.com/support.
f. Tap the Connect button. This provisions the scanned
microinverters on the Envoy-S.
g. When prompted, confirm the number of microinverters that you
installed.
h. 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
a. Use the Installer Toolkit mobile app to set the number of
microinverters the Envoy-S should search for on the power line.
b. Connect to the Envoy-S with your mobile device as described in
the side note.
c. Launch Installer Toolkit and tap Connect to an Envoy.
d. When prompted, enter the number of microinverters that you
installed.
e. When prompted to start a device scan, tap OK.
The Microinverter Communications LED flashes 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.
Method C: Discover Microinverters with the Envoy-S
If you are not using the Installer Toolkit app, press the Device Scan button on the Envoy-S. With this
method, the Envoy searches the power line for 15 minutes, but does not know how many microinverters it
should discover.
The Microinverter Communications LED flashes green for 15 minutes while scanning. At the end of the
scan, it lights solid green if at least one microinverter was discovered or solid amber if no microinverters were
discovered (or if any discovered microinverter stops communicating).
With All Methods
If the Microinverter Communications LED remains solid, see “Microinverter Detection Issues” on page 34.
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.
 On the Envoy-S, if the AP
Mode LED is not lit,
press the AP Mode button.
 On your mobile device, go
to Settings and join the Wi-
Fi network “Envoy_nnnnnn”
(where “nnnnnn” represents
the final six digits of the
Envoy serial number).
