Enphase Mobile modem prides itself that if you have no internet, then it shan't be a problem. Simply plug the pre-configurated mobile modem into either Envoy-S or IQ-Envoy USB port for the swift setup. The Envoy-S or IQ Envoy stores 15-minute, microinverter, meter and Enphase Battery performance data. Mobile Connect reports 15-minute data to Enlighten four times a day. Historical performance is presented in both Enlighten Manager and MyEnlighten.
