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 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 [e-mail] 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 load center.
9. Contact Enphase Support at [e-mail] 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 a Hardwired Envoy-S
If Enphase Customer Support authorizes 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. Do not energize the sensed circuit until the CT leads are installed in the terminal
block. Do not disconnect the CT leads from the terminal block while the sensed circuit is
energized.
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 subpanel, always de-energize the subpanel
before servicing.
WARNING! When replacing an Envoy-S that uses a production CT (model ENV-S-AM1-
120), 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, L2, L3 (if used) and Neutral wires from the old Envoy.
3. Disconnect the Ethernet cable (if used).
4. Turn off the circuit breaker supplying the microinverters.
5. Disconnect the production CT.
6. Unlatch the split-core of the consumption CTs (if used) before disconnecting. Once the CTs are
unlatched, remove them from the sensed wires.
7. Inspect the CTs for damage. If they are damaged, you must order another pair (order CT-200-
SPLIT).
