Product Overview

The Enphase CT-200-SPLIT is a split-core 200 A current transformer for metered IQ Gateways (and IQ Combiner) to measure household consumption without cutting the conductor.

Accuracy is ±2.5% on Enphase Americas documentation. The IQ Gateway has metering ports for up to two consumption CTs (DSH-00111-6.0).

Best For

  • Adding consumption metering to a metered IQ Gateway that does not already have clamp CTs installed.
  • Retrofits where a split-core CT is preferred so the conductor does not need to be cut (unlike a solid-core production CT).

What You May Also Need

Usually required

  • A metered IQ Gateway or IQ Combiner with available consumption CT terminals.

May be required

  • IQ Gateway ENV2-IQ-AM1-240 when a standalone gateway needs consumption CTs.
  • CT-200-CLAMP if the combiner or design calls for clamp-style CTs instead of split-core.

Optional upgrades

Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.

Important Considerations

  • Follow Enphase polarity / arrow orientation; reversed CTs produce incorrect import/export readings.
  • IQ Combiner 5 ships with two consumption clamp CTs; IQ Combiner 6C consumption CTs are ordered separately (DSH-00585-4.0). Match the CT type the QIG specifies for that enclosure.
  • Professional installation required. Follow Enphase instructions and the NEC.
