3.
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.
4.
Connect the Envoy-
S to Enlighten as described in “7. Connect to Enlighten” on page 19.
5.
Verify that the new Envoy-S Network Communications LED
lights green within five
minutes. If not, follow the network troubleshooting steps on page 36.
6.
If possible, log in to Enlighten and add the Envoy-S to the Activation for this system by
clicking “
Add Another Envoy
” under the “
Envoy”
section.
7.
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
daylig
ht 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.
8.
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.
9.
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.
10.
Ship the old Envoy-S to Enphase using the supplied RMA shipping label.
Replacing an Hardwired Envoy-S
If Enphase Customer Support authorises an Envoy-S replacement (RMA), perform the following steps.
DANGER!
Risk of electrocution! CTs must be installed with no current flowing in the
sensed circuit. Always install CT wires in the terminal blocks before energising the
sensed circuit. Do not disconnect the CT leads from the terminal block while the sensed
circuit is energised.
DANGER!
Risk of electric shock. Be aware that installation of this equipment includes
risk of electric
shock
. If you wire the Envoy-S at the sub-board, always de-energise the
sub-board before servicing.
WARNING!
When replacing an Envoy-S that uses a production CT (model ENV-S-WM1-
230), you must install the new production CT included with the replacement Envoy-S.
1.
Turn off the circuit breaker supplying Envoy-S.
2.
Disconnect the L1 and Neutral wires from the old Envoy.
3.
Disconnect the Ethernet cable (if used).
4.
Turn off the circuit breaker supplying the microinverters.
