7. Detect the Devices
Use one of the following methods to detect any Enphase Microinverters and/or AC Batteries.
NOTE: In systems where a central disconnect (contactor) is installed, you must use Installer
Toolkit to configure the meters as described in Step 8 before device discovery can complete.
Method A: Provision Devices with Installer Toolkit
Use the Installer Toolkit to configure the Envoy-S with the serial numbers of the installed Enphase
devices.
a. Select the system you are working with, or tap [+] to add a system.
b. 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.
c. Following the on-screen instructions to create the arrays and scan the serial numbers from the
installation map.
d. Tap the Connect button. This provisions the scanned devices on the Envoy-S.
e. When prompted, confirm the number of Enphase devices installed and select a grid profile.
The Device 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 Devices with Installer Toolkit
Use the Installer Toolkit mobile app to set the number of Enphase devices that the Envoy-S should search
for on the power line.
f. Tap Connect to an Envoy.
g. When prompted, enter the number of Enphase devices installed and select a grid profile.
h. When prompted to start a device scan, tap OK.
The Device Communications LED flashes green while scanning. It lights solid green when all of the
installed Enphase devices are communicating or solid amber if any are not communicating.
Method C: Discover Devices with the Envoy-S
If you are not using the Installer Toolkit mobile 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 Enphase
devices it should search for.
The Device Communications LED flashes green for 15 minutes while scanning. At the end of the
scan, it lights solid green if at least one device was discovered or solid amber if no devices were
discovered (or if any discovered device stops communicating).
NOTE: If you are not using Installer Toolkit, you must log in to Enlighten and set the grid
profile for the system.
With Both Methods
If the Device Communications LED remains solid amber, see “Device Detection Issues” on page 34.
