Enphase Enlighten Monitoring

Enphase Enlighten enables a new level of performance, reliability and management for solar energy installations. Enlighten is integrated into the Enphase Microinverter System and provides unprecedented visibility into the performance of every solar module. Upon logging in to the online portal, home owners and installers get an at-a-glance view of the status their entire system is performing as well as provide visual alerts for anything that requires attention.

Enlighten at Work


Enlighten constantly monitors every module and compares its performance to each of its neighboring modules to identify any production issues.


Using its built-in analysis algorithms, Enlighten analyzes production shortfalls, establishes a possible cause and suggests solutions to remedy the situation.


Enlighten promptly sends an alert to the system ownder or installer per the user-defined preferences established at installation.

Benefits of Enlighten

Plug-and-Play Installation

Enphase Energy's per-module monitoring technology is integrated into the Enphase Microinverter System which means that you do not need to purchase or install a bolt-on or stand-alone third-party monitoring tool. The Enphase Envoy (EMU) communications gateway plugs into any standard AC outlet and collects micro-inverter performance information over the existing power line. No additional wiring is required. By plugging the Ethernet cable of the Envoy into a broadband router, performance data is automatically transmitted to Enlighten using the site’s existing internet connection, further simplifying installation.
