Ensemble by Enphase is an energy operating system that allows Enphase IQ microinverters to provide power to your home, whether you are connected to the grid or not. At the time of writing, this technology has not been released to market yet, and these product guidelines and specifications may change once the technology is out.
When an Enphase microinverter utilizes Ensemble 1.0 technology, it acts as a grid-forming bi-directional multimode inverter. Specifically, under Ensemble 1.0, the IQ microinverter becomes a UL 1741 listed Microgrid Interconnect Device (MID) with Neutral Forming Transformer (NFT). This allows the microinverter to create an IEEE 1547 intentional island. The initial release will be for single-phase residential 120/240V systems only (no three-phase).
The system components provide multi-tiered system control. The software dictates whether the microinverter behaves in a grid-tied or grid-independent matter, whether the microinverter is used as an inverter or a charge controller, and to what extent the microinverter is used for power conversion for Encharge batteries.
