• One 2-pole, 20A circuit breaker for each microinverter branch circuit, suitable for backfeed operation
• A NEMA type 3R, 4, or better enclosure with hinged or screw cover for housing the IQ Envoy
• An IQ Envoy (ENV-IQ-AM1-240)
• Miscellaneous conduits, fittings and conductors to make a code compliant installation
Conceptual Schematic of an IQ Envoy and Solar Subpanel Installation
Installing the IQ Envoy in an Outdoor Enclosure
The IQ Envoy must be installed inside an electrical enclosure for protection and to keep the operating
temperature of the IQ Envoy within range. This enclosure must be large enough to house the IQ Envoy. The
enclosure can be metal or non-metallic but should be non-metallic if wi-fi or an Enphase Mobile Connect
cellular network is used for the Internet connection. The enclosure must meet the following requirements:
Use a NEMA type 3R, 4, or better rated outdoor enclosure with hinged cover or screw cover of suitable
dimensions. Typical enclosure dimensions are in the range of 10” x 10” x 4” to 12” x 12” x 6”.
IQ Envoy Requirements
• Comply with all instructions found in the IQ Envoy Quick Install Guide
• It is important to locate the IQ Envoy next to the solar subpanel and electrically connected in the
solar subpanel.
• When installing the IQ Envoy in an enclosure, choose an area for installation where ambient
temperature does not exceed 46º C (115º F).
• The IQ Envoy does not ship with a plug-in style power cord and must be hard-wired to two lines and
a neutral for power, microinverter communication, and to support production and consumption
metering. Therefore, a receptacle is not required in the enclosure for powering the IQ Envoy.
o Only if an Ethernet over powerline communication (PLC) bridge is desired should a
receptacle be installed inside the enclosure. The enclosures listed on page 3 provide
adequate room for a receptacle, if needed.
• The enclosure should be installed in a location that is shaded from extensive periods of direct
sunlight. The IQ Envoy is rated for ambient temperatures of -40°F to 115°F when installed in an
enclosure.
• If mounted outdoors, do not drill holes on the top of the enclosure or anywhere that allows moisture
ingress.
