Enphase Enpower Smart Switch IQ System Controller

The IQ System Controller connects the home to grid power, the IQ Battery system, and solar PV. It provides microgrid interconnect device (MID) functionality by automatically detecting and seamlessly transitioning the home energy system from grid power to backup power in the event of a grid failure. It consolidates interconnection equipment into a single enclosure and streamlines grid-independent capabilities of PV and storage installations by providing a consistent, pre-wired solution for residential applications.

Features

• Controls safe connectivity to the grid
• Automatically detects grid outages
• Provides a seamless transition to backup
• Connects to the load or service equipment side of the main load panel
• Centered mounting brackets support single-stud mounting
• Supports conduit entry from the bottom, bottom left side, and bottom right side
• Supports whole home and partial home backup
• Includes neutral-forming transformer for split phase 120/240 V backup operation
