5.
Unlatch the split-core of the production CT (if used) before disconnecting. Once the CT is
unlatched, remove it from the sensed wires.
6.
Unlatch the split-core of the consumption CT (if used) before disconnecting. Once the CT is
unlatched, remove it from the sensed wires.
7.
When the replacement Envoy-S arrives, install the Envoy-S and provide power as described
in “2. Provide a Power Connection” on page 13.
8.
Install the new production CT and consumption CT (if used) as described in
“3. Install CTs
for Metering (Model ENV-S-WM1-230 only)
” on page 16.
9.
Verify that the new Envoy-S powers up.
BEST PRACTICE:
When powered up and connected for the first time, the Envoy-S may
retrieve an automatic upgrade from Enphase. This upgrade may take up to 15 minutes.
During upgrade the Envoy-S LEDs flash green sequentially.
WARNING!
Risk of Equipment Damage. Do not remove power from the Envoy-S if the
Envoy-S LEDs are flashing green sequentially. This indicates that a software upgrade is
in progress.
10.
Connect the Envoy-
S to Enlighten as described in “7. Connect to Enlighten” on page 19.
11.
Verify that the new Envoy-S Network Communications LED
lights green within five
minutes. If not, follow the network troubleshooting steps on page 36.
12.
If possible, log in to Enlighten and add the Envoy-S to the Activation for this system by
clic
king “
Add Another Envoy
” under the “
Envoy”
section.
13.
Verify that the new Envoy-S starts discovering microinverters within 20 minutes of starting
up. If necessary, use the Enlighten or Device Scan button to start a new device scan during
daylight hours. (See
“Initiate a New Scan for Microinverters” on page 24.)
NOTE
: If the old Envoy-S has communicated to the microinverters on the same day that
the new replacement Envoy-S is installed, the new Envoy-S will be unable to discover
the microinverters. Contact Enphase at
enphase.com/global/support-request
for
assistance in this situation.
14.
Assess the power line communications by running a Communication Check from Enlighten
or the Installer Toolkit. If the communication check shows poor power line communications,
relocate the Envoy-S closer to the Switchboard.
15.
Contact Enphase Support at
enphase.com/global/support-request
to have the new Envoy-S
added to your system and to retire the replaced Envoy-S.
16.
Ship the old Envoy-S to Enphase using the supplied RMA shipping label.
