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 Microinverter Communications States
A detected microinverter is one that has been discovered via the Envoy’s device scan or provisioned via
Installer Toolkit or Enlighten.
The states of the Microinverter Communications LED
have slightly different meanings, depending on
whether the installer has provided an expected number of microinverters. If you have NOT provided the
expected number of microinverters 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 microinverters 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 microinverters, this displays as described in the
“
With provisioning
”
column.

Green Solid

The

was discovered and all are
communicating.
All of the

devices are
communicating.
Amber Solid
At least one of the
discovered devices is not
communicating.
The number of devices
communicating is not equal to the
number expected (e.g., 0/12, 1/12,
11/12, or 13/12).
The devices that are
communicating are not the same
as those provisioned.
Initiate a New Scan for Microinverters
The Envoy-S identifies each device by its unique serial number. If you add more microinverters to an
existing system or replace a microinverter or the Envoy-S, you can run a scan to detect the new devices.
To initiate a scan after you add new microinverters 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
microinverters deployed at the site. The Microinverter 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 microinverter, and use Array Builder to add the new
microinverter to the virtual array.
3.
After the microinverter is detected, it is best to disable the scan. To do this, press the Envoy-
S
Device Scan
button again.
