Enphase XA-ENV2-PCBA-4 Replacement IQ Gateway PCBA

Enphase IEEE 1547:2018 IQ Gateway Replacement Board

The Enphase XA-ENV2-PCBA-4 is an internal gateway replacement circuit board built for Enphase IQ Combiner 4 and 4C units. It replaces damaged gateway electronics to restore system communication, remote monitoring, and control across your solar installation. This board is also backward compatible with IQ Combiner 3, 3C, 3-ES, and 3C-ES models.

Compliant with the IEEE 1547:2018 grid interconnection standard, the circuit board manages data collection for both solar production and home energy consumption. It installs directly inside your existing combiner box enclosure using your current wiring and CT transformers. Replacing only the internal printed circuit board saves money by avoiding a complete combiner box or gateway system replacement.
