IQ System Controller

The IQ System Controller connects the home to grid power, IQ Batteries, and solar PV.

IQ System Controller (EP200G101-M240US00) is recommended only for retrofitting existing Solar Only systems with M Series, IQ6 Series, or IQ7 Series Microinverters.

For new installs or retrofits of Solar Only systems with IQ8 Series Microinverters, use IQ System Controller 2 (EP200G-SC2-RSD-KIT).

IQ System Controller provides microgrid interconnection 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.
