The Envoy Communications Gateway (Envoy) is required in order to interface with the microinverters and includes access to the Enphase Enlighten online monitoring service. It can also be accessed locally via a computer web browser for operation information.
The Envoy plugs into any standard AC outlet and collects microinverter performance information over the existing power line. An Ethernet cable or WiFi adapter (choose above) can then be used to connect the Envoy to the installation site's existing Internet access point or local area network. Once online, the Envoy will automatically access the Enphase Enlighten web service.
The Envoy's LCD display provides at-a-glance performance data, and more detailed per-module information is accessible through the Enphase Enlighten website, which displays each module's real-time performance data in a physically accurate representation of the system. The Enphase Enlighten service can also notify the user or service staff via email when it detects underperforming modules or system faults. One Envoy is required for monitoring on each installation of up to 250 inverters. The Envoy is Listed to UL 60950.
