Enphase IQ System Controller The Enphase IQ System Controller (and IQ System Controller 2) is used in the Enphase Energy System to streamline installations by providing grid isolation and locations to connect Enphase IQ Batteries, the IQ Combiner, and in the case of the System Controller 2, adding a generator, as needed. The IQ System Controller includes a neutral-forming transformer, Microgrid Interconnect Device (MID), and an Eaton BR series busbar assembly that can support up to a 200A main breaker and is rated to 120/240 VAC. Circuit breakers are not included and need to be sourced and installed, configured to your specific installation. IQ System Controller Handles are recommended for easier and proper mounting of the IQ System Controller on a wall. The handles can be reused at other installation sites. EP200G101-M240US00
