PV module. System monitoring Once you install the Enphase IQ Gateway and provide an internet connection through a broadband router or modem, the Enphase IQ Microinverters automatically begin reporting to Enphase App. The Enphase App presents current and historical system performance trends and informs you of PV system status. -

IQ7X-96-2-INT MC-4 locking type Pair only with 96-cell modules NOTE: Some Enphase microinverters will not begin exporting power until the IQ is installed Gateway and has detected all the microinverters at the site. In addition, the grid profile may need to be configured and the IQ must have propagated these settings to the microinverters. -

WARNING: Risk of electric shock. Always de-energize the AC branch circuit before servicing. Never disconnect the DC connectors under load. WARNING: The Enphase microinverters are powered by DC power from the PV modules. Make sure you disconnect the DC connections and reconnect the DC power and then watch for the solid green about six seconds after connection to DC power. -

L. Swap DC leads with a known good, adjacent PV module. If after checking Enphase Installer Portal periodically (this may take up to 30 minutes), the problem moves to the adjacent module, this indicates that the PV module isn’t functioning correctly. If it stays in place, the problem is with the original microinverter. -
