DATASHEET
<br />IQ System Controller 3/3G
<br />The Enphase IQ System Controller 3/3G connects the home to grid power, the IQ Battery
<br />system, and solar PV. It provides microgrid interconnect device (MID) functionality by
<br />automatically detecting and seamlessly transitioning the home energy system from grid power
<br />to backup power in the event of a grid failure. It consolidates interconnection equipment into a
<br />single enclosure and streamlines grid-independent capabilities of PV and storage installations by
<br />providing a consistent, pre-wired solution for residential applications.
<br />Easy to install
<br />• Connects to service entrance¹ or main
<br />load center
<br />• Includes neutral-forming transformer
<br />• Mounts on single stud with centered
<br />brackets
<br />• Provides conduit entry from the
<br />bottom, left, or right
<br />• Includes color-coded wires for ease of
<br />wiring the System Shutdown Switch
<br />• Integrates hold-down functionality to
<br />eliminate the need for hold-down kits
<br />and special breakers
<br />Flexible
<br />• Can be used for Sunlight Backup,
<br />Home Essentials Backup, or Full Energy
<br />Independence
<br />• IQ System Controller 3 integrates with
<br />IQ Battery 5P
<br />• IQ System Controller 3G integrates
<br />with select AC standby generators. See
<br />the Generator integration tech brief for
<br />a list of generators
<br />• Provides a seamless transition to
<br />backup
<br />Safe and reliable
<br />• System Shutdown Switch can be
<br />used to disconnect PV, battery, and
<br />generator systems
<br />• System Shutdown Switch acts as a
<br />rapid shutdown initiator of grid-forming
<br />IQ8 PV Microinverters for the safety
<br />of maintenance technicians/first
<br />responders
<br />• 10-year limited warranty
<br />(1) IQ System Controller 3 is not suitable for use as service equipment in Canada.
