8. When the replacement Envoy-S arrives, install the Envoy-S and provide power as described in
“2. Provide a Power Connection” on page 12.
9. Install the new production CT and replace the consumption CTs (if used) as described in “3.
Install CTs for Metering (Model ENV-S-AM1-120 only)” on page 15.
10. 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.
11. Connect the Envoy-S to Enlighten as described in “7. Connect to Enlighten” on page 19.
12. Verify that the new Envoy-S Network Communications LED lights green within five minutes. If
not, follow the network troubleshooting steps on page 36.
13. 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.
14. 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.
15. 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.
16. Contact Enphase Support at [e-mail] to have the new Envoy-S added to
your system and to retire the replaced Envoy-S.
17. Ship the old Envoy-S to Enphase using the supplied RMA shipping label.
