The Enphase Mobile Connect cellular modems deliver easy, reliable networking for Enphase Systems using S and IQTM Series Envoys. The modem supports up to 60 microinverters. The Cellular Modem connects the EnvoyTM S or IQTMEnvoy to the EnlightenTM Cloud through LTE-M cellular connectivity. It eliminates the need for an on-site Internet connection to monitor an Enphase system. The modem is pre-configured and is activated when connected to the Envoy. The Envoy collects module-level and system-level production data, and, if configured, consumption data, at pre-defined periods of time, typically at 15-minute intervals. It transmits to the EnlightenTM Cloud four times a day.
