Your installer will register your system with Enphase using the email address you provided to them during the sales process. There are no additional steps you need to take to activate Enlighten monitoring for your system, and the software is free for system owners. (If you have recently purchased a home with Enphase equipment already installed, please jump to Change of Ownership below.)
After your installer receives notice that you have permission to operate your solar system (PTO), your installer will power on your system. Most systems can be powered on remotely, but occasionally, installers may come out to your house again to power on your system.
After your system is powered on and has operated successfully for 24 hours, you will be sent your Enlighten login credentials. Your username is the email address you provided to your installer. You will be sent a temporary password that you will reset when you first log on.

Look for your welcome email in your spam or junk folder if you do not receive it within three days of system turn-on following PTO.
If you have deleted your welcome email, you can request a new password by visiting enlighten.enphaseenergy.com and clicking "Forgot your password?"
