I wrote a driver for this long time ago: GitHub - mr-manuel/venus-os_dbus-enphase-envoy: This Venus OS driver gets the data from the Enphase Envoy-S and displays it as PV Inverter. It works for all phase combinations. Additionally it's possible to post the data to multiple MQTT topics to get more detailed informations/monitoring for the Enphase system and single inverters.
In the meanwhile it is also natevly supported by Victron with Venus OS v3.60: Help needed - SMA, Solar Edge, Kostal, Enphase and others
