Today, the IQ® System Controller brings it all together, as it performs the Beginning in 2025, we expect to move the MID into a meter collar to simplify functions of a microgrid interconnection device (MID) for safety, power backup installations in North America. This simplies the installation cost aggregation, connectivity, and neutral-forming. It interfaces with the grid, particularly for meter-main combo panels in California, where the meter solar microinverters, batteries, EV, home loads, and provides local control, and the main load center are within the same structure. In addition, with the as well as receives instructions from the cloud and dispatches them to neutral-forming function present in the fourth-generation battery, an external the distributed energy resources onsite. The IQ Gateway uploads data to transformer, which was previously embedded in the IQ System Controller the Enphase cloud at a regular cadence and all this data is available at the is no longer needed. Once that is done, the IQ® Combiner can be used for homeowner’s ngertips through the Enphase App. The Enphase App provides “Beginning in 2025, we expect to connectivity and aggregating power obviating the need for an IQ System deep insight into the consumption and production of energy in the home and move the MID into a meter collar Controller in North America.
