Replacing an Envoy-S
If problems remain after following the troubleshooting steps above, contact Enphase at
[e-mail].
DANGER! Risk of electric shock. Risk of fire. Do not attempt to repair the Envoy-S; it
contains no user-serviceable parts. Tampering with or opening the Envoy-S will void the
warranty. If the Envoy-S fails, contact Enphase Customer Support for assistance
([e-mail]).
 Warranty void if cover removed.
 Refer servicing to qualified personnel.
If Enphase Customer Support authorizes an Envoy-S replacement (RMA), perform the following steps.
DANGER! Risk of electrocution! When replacing the Envoy-S Metered, 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.
DANGER! Risk of electric shock. Risk of fire. If the Envoy-S is wired for metering, only
qualified personnel should install or replace the Enphase Envoy-S.
WARNING! When replacing the Envoy-S Metered, you must install a new production CT to
maintain metering accuracy. A new production CT is included with the replacement Envoy-S.
WARNING! If the Envoy-S you are replacing uses an Enphase cellular modem (Enphase
Mobile Connect), do NOT move the cellular modem to another installation site. This de-
activates the modem.
Replacing an Envoy-S Standard with AC Power Cord (Model ENV-S-AB-120-A)
1. Disconnect the Ethernet cable (if used) and power cord from the old Envoy-S.
2. When the replacement Envoy-S arrives, power it as described in “2. Provide a Power
Connection” on page 12.
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. Because this upgrade may take up to 15
minutes, connect the Envoy-S first at the site (connect to both AC power and the broadband
router) so that it performs the upgrade well before the solar module installation is complete.
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.
