IQ Meter Collar quick install guide
The Enphase IQ Meter Collar is a meter socket adapter with integrated microgrid interconnection device (MID) and current sensors for energy consumption
metering. The IQ Meter Collar is rated at 200 A and can be installed on an ANSI C12 Form 2S meter socket rated up to 200 A continuous operation. It can be
installed either at the service entrance directly on the utility meter socket or on a load-side standalone meter socket.
The IQ Meter Collar is compatible with 3
compatible with 4
generation Enphase Energy Systems installed with the IQ Combiner 6C and IQ Battery 10C.
th
IQ Meter Collar can be used in Enphase grid-interactive (grid-tied) as well as multi-mode (grid-forming) installations. In grid-interactive installations, the
IQ Meter Collar serves as a consumption metering device, eliminating the need for additional CTs to be field wired. In grid-forming installations, the
IQ Meter Collar provides both consumption metering and grid isolation to enable microgrid formation.

Junction box When the IQ Meter Collar is installed on a separate meter socket, a jumper cover is required to bypass the need for a watt-hour meter. In this configuration, the IQ Meter Collar measures energy consumed by loads connected to the backup panel. -
Page 5: Before Installation
If the IQ Meter Collar is not approved by the local utility, and the premise does not have a meter-main combo panel at the service entrance, then scenario 2A may be selected for whole home backup. - Page 6 Insert in plastic bag Insert the IQ Meter Collar assembly (with the junction box and control cable in case of ringed meter sockets) along with the seal ring in the plastic bag provided with the package. If the meter socket is ringless, only the IQ Meter Collar along with seal ring needs to be inserted in the plastic bag.
- Page 7 With the TOP marking on the IQ Meter Collar facing up, insert the rear side four blades of the IQ Meter Collar into the meter socket. CAUTION: Do not remove the blank protective cover in front of the IQ Meter Collar until it is inserted into the meter socket jaws. The blank cover helps prevent the live jaws on the front of the IQ Meter Collar from accidental contact while inserting it into a live meter socket.
