Power export limit for IQ7 and IQ8 Series Microinverter systems
Primary protection Secondary protectionProduction and Consumption CTsWhen commissioning CTs:Grid profileAn Enphase IQ7 or IQ8 system can support the power export limit by using a power export limit grid profile and an IQ Gateway with Production CTs installed at the solar PV sub-panel and Consumption CTs installed at/near the utility service location. When configured for power export limit, the Enphase system automatically limits the PV generation soSee more on enphase Knowledge Center[PDF]
