LED Behaviour at Initial Start Up
When the Envoy-S starts up for the first time, it goes through the initial boot sequence. During this initial
boot sequence, all the Envoy-S LEDs are flashing amber. If the Envoy-S retrieves a software update soon
after connecting to the Internet, the LEDs flash green sequentially during the upgrade.
WARNING! Risk of Equipment Damage. Do not remove power from the Envoy-S if the LEDs
are flashing green sequentially. This indicates that a software upgrade is in progress.
Initial Communications Check
The Envoy-S normally indicates no Internet connection for two to three minutes after the first start up. It
then sends the first report to Enlighten. When Enlighten responds, the Network Communications LED
lights solid green, indicating an Internet connection to Enlighten.
More about Device Communications States
A detected Enphase device is one that has been discovered via the Envoy’s device scan or provisioned
via Installer Toolkit or Enlighten.
The states of the Device Communications LED have slightly different meanings, depending on
whether the installer has provided an expected number of devices. If you have NOT provided the
expected number of devices either through the Activation form or in Installer Toolkit, the LED displays as
described in the “No expected number provided” column. If you have provided the expected number of
devices in the Activation form or in Installer Toolkit, this LED displays as described in the “Expected
number provided” column. If the Envoy has been provisioned with the serial numbers of the devices, this
displays as described in the “With provisioning” column.
Initiate a New Scan for Devices
The Envoy-S identifies each device by its unique serial number. If you add more devices to an existing
system or replace an Enphase Microinverter or Enphase AC Battery, you can run a scan to detect the new
devices. To initiate a scan after you add new devices to an existing Enphase system, perform the
following steps.
1. Press the Device Scan button. The Envoy-S begins a 15-minute scan to identify all of the
Enphase devices deployed at the site. The Device Communications LED flashes green
during the scan. Alternatively, you can initiate a scan using Installer Toolkit.
2. Log into Enlighten to check for the new device, and use Array Builder to add the new device
to the virtual array.
3. After the device is detected, it is best to disable the scan. To do this, press the Envoy-S
Device Scan button again.
