The Enphase IQ Gateway Metered is an integrated component of the Enphase Energy System that acts as a communication bridge between the Enphase IQ Microinverts located on the roof and the Enphase App for remote control and monitoring.
The IQ Gateway Metered communicates with the IQ Microinverters via standard AC power lines and the Enphase App via cellular or wireless internet. The IQ Gateway allows homeowners to control grid management functions, monitor solar production, and monitor home energy consumption with a pair of demand current transformers (CTs) included.
Note that the package includes two 100 A current transformers but in case of 3-phase installation, a total of 6 pcs (two for each phase) are required for production and consumption monitoring.
