Create the Map and Install the PV Modules and Microinverters

Create the map and install the PV modules and microinverters as directed by the installation
•
manuals. You can scan this map later using Installer Toolkit and your mobile device.
NOTE: If needed, you can find an installation map at the back of any Enphase Microinverter
manual.
Create a paper installation map to record microinverter serial numbers and positions in the array.
•
Peel the removable serial number label from each microinverter and affix it to the respective
location on the installation map. You can scan this map later using the Enphase Installer Toolkit
and your mobile device.
Peel the removable label from the bottom of the Envoy-S and affix it to the installation map.
•
Always keep a copy of the installation map for your records.
