AlphaESS SMILE-G3-T10 10 kW Three-Phase Hybrid Inverter

The SMILE-G3-T10 is the 10 kW inverter of AlphaESS's third-generation SMILE home storage system. Three separate MPP trackers make it a good fit for roofs split across several orientations, and it accepts twice its rated power in panels, so a 20 kW array can sit behind a 10 kW grid connection. Battery modules stack beside it in the same 610 x 212.5 mm footprint, and when the grid drops the backup port takes over as a UPS for the house.
