Enphase IQ Combiner Box w/ IQ Envoy

The Enphase IQ Combiner™ with Enphase IQ Envoy™ consolidates interconnection equipment for an Enphase IQ Microinverter solar system into a single enclosure and streamlines PV installations. This combiner box combines up to four electrical enclosures into one, eliminating the need for a separate subpanel, meter enclosure, Envoy enclosure, and AC disconnect, as well as all the hardware that would be required to connect those pieces together.

The Enphase IQ Combiner Box gives installers the option of using standard electrical components to transition branch circuits from the roof to the ground level. The Combiner Box can be configured with consolidated metering and networking equipment, including a preconfigured IQ Envoy communications gateway. Learn more about Enphase IQ Envoy.

This combiner box provides a consistent, pre-wired solution for residential applications. It is often configured with integrated revenue grade PV production metering (ANSI C12.20 +/- 0.5%) and optional consumption monitoring (+/- 2.5%).
