No, export limiting functionality is not yet compliant with RD 244/2019. Most installations with Enphase microinverters are residential scale (below 15kW) and are easily accepted without this compliance.​

Each microinverter is a single phase device. Three-phase installations are constructed with single phase microinverters distributed across the phases. The inverter will monitor power consumption at each phase using the CTs connected to the Envoy-S communications gateway, limiting grid export to the defined level, either on a per phase or aggregate basis as required.​In three-phase installations, can you divide surpluses by phases?

If an issue is detected via the Enlighten monitoring platform, please contact Enphase Customer Support. If the issue is related to the microinverter, Enphase will provide any service required under their warranty coverage. If Enphase determines the issue is related to the panel, the service will be transferred and supported by Maxeon Solar Technologies under the appropriate SunPower panel line warranty.

Enphase microinverters offer export control by reducing power production at each microinverter to maintain export to a defined power level—which can be zero for a zero-export site. The microinverters do not offer control of surplus power beyond export to the electricity network.​

Sunlight must be present for the system to generate electricity. At night, your system will hibernate, and your inverter will display a blank screen.
