disconnect tool.
E. Press each of the four clips to free the microinverter.
F. Snap new replacement microinverter into place.
G. Connect the PV Module DC connectors to the microinverter.

I. Bring the AC Module back onto the roof or other mounting location.
J. Connect the AC Module AC connector and DC Connector to the Q Cable.
K. Energize the AC branch circuit breaker and verify operation of the replacement microinverter by checking
the Status LED on the connector side of the microinverter.
L. On the ground, use the Installer Toolkit mobile app to delete the old microinverter serial number from the
Enphase Envoy-S database. In Installer Toolkit, once connected to the Envoy:
a. Tap Micros > Manage.
b. Tap the checkbox to the right of the microinverter serial number that you replaced.
c. Tap to delete the microinverter from the Envoy-S database.
M. Add the new microinverter serial number to the Envoy database by initiating a device scan using one of the
following methods
：
Method 1: Initiate a scan using the Installer Toolkit mobile app
a. In Installer Toolkit, once connected to the Envoy-S, navigate to the Overview screen.
b. From the Overview screen, tap
Detected > Start Device Scan
to start a new 30- minute device scan.
c. If device scanning on the Envoy is inhibited, the app displays Scan Inhibited. If you need to add more
microinverters to the system when device scanning is inhibited on the Envoy, you must use the Installer
Toolkit scanning tool to provision them on the Envoy-S, rather than using the Envoy-S device scanning
function to discover them. If this is not possible and you need to enable device scanning on the Envoy-S,
contact Enphase Customer Support at enphase.com/en-us/support/contact.
Method 2: Use an Envoy-S
a. Press the Device Scan button on the Envoy-S. The Envoy-S begins a 15-minute scan to identify all of the
microinverters deployed at the site. The Microinverter Communications LED
flashes green during the scan.
