M250 Installation Planning

Installation Flow

Every Enphase installation should include these basic steps. Plan to complete these steps in the order

shown.

1. Register the System

 First-time installers: go to https://enlighten.enphaseenergy.com/users/new and complete the form.

Your login credentials will be emailed to you.

 Existing installers and those with new credentials: Log into the Enphase Enlighten

software.

 Click “Add a New System” in the Installation Status widget.

2. Install the Envoy

 Install the Envoy

Communications Gateway as directed by the installation manual.

 Locate a dedicated AC outlet close to the load center. Place the Envoy so that its AC cord can

reach this outlet.

 Plug the Envoy into the dedicated AC outlet and connect it to a broadband router. Wait for the

Envoy to display "+Web".

 Allow 20 minutes in case a software upgrade is required. Do not unplug the Envoy during

software upgrade!

 Set up the Grid Profile for your region, if required.

3. Install the PV Modules and the Enphase Microinverters

 Install the PV modules and microinverters as directed by the installation manuals.

 Use the ArrayGun to scan the microinverters. For more information, go to

http://enphase.com/products/arraygun.

 As an alternative, you can manually build the map: Peel the removable serial number label from

each microinverter and affix it to the respective location on the map.

4. Complete the Set Up

 Ensure at least 3 level bars and the correct number of microinverters are showing on the Envoy

LCD screen.

 Once the Envoy has detected the microinverters, log in to Enlighten to use the Array Builder. For
