Step 1: Connect the Envoy
a. Connect the Envoy to power and Internet according to the Envoy Quick Install Guide.
b. Wait for the "+Web" indication on the Envoy's LCD screen.
c. Leave the Envoy running while you install the microinverters so that any required Envoy
software upgrade completes.
BEST PRACTICE: When powered up and connected for the first time, the Envoy may
retrieve an automatic upgrade from Enphase. Because this upgrade may take up to 20
minutes, connect the Envoy 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.
WARNING! Do not remove power from the Envoy if the LCD displays:
"Upgrading. . . Do Not Unplug."
