Enphase Envoy Energy Management Unit
Formerly the EMU
Manufacturer Part Number: IEMU-02
The IEMU-02 now includes lifetime Enlighten monitoring.
The Enphase Envoy Communications Gateway is the networking hub connecting every module and microinverter in your solar array to the internet. Lifetime monitoring for all panels now comes standard with the EMU.
The Envoy uses advanced power-line communications technology to connect to each microinverter without additional wiring or wireless configuration. System owners can easily check the status of their solar system using the Envoy’s LCD display, or get more detailed information through the Enlighten website.
For commercial installations, multiple Envoy devices are used in combination with Line Communications Filters (LCF) to separate networking domains across the site.
