The Deye 30KVA 3-Phase High Voltage Solar Inverter is a large-scale hybrid solar inverter aimed at commercial installations, small industrial sites or sizeable residential estates needing three-phase power backup and solar integration — well beyond single-phase household inverter capacity. At 30kVA it's built to manage significant simultaneous solar generation, grid interaction and battery charging/discharging across all three phases. It requires a high-voltage battery bank rather than the low-voltage (48V-class) batteries used with smaller residential inverters, which is a real compatibility constraint buyers need to plan for — this is not a plug-and-play add-on to an existing low-voltage battery setup.
