The Deye Sun-12K-SG04LP3-EU is a 12kVA/12kW three-phase hybrid solar inverter, grid-tied and battery-compatible, aimed at larger homes, small commercial sites or three-phase installations where a single-phase inverter (like Deye's SG02LP1 range) wouldn't balance the load correctly across all three phases. As with other Deye hybrid units, it combines solar charging, battery storage management and grid/backup switching in one unit, letting a site run on solar and battery power during a grid outage or load-shedding stage while feeding excess solar back where permitted. Being three-phase, it's suited to properties with a three-phase electrical supply rather than the more common single-phase residential connection. Battery voltage window, MPPT specification and compliance certification aren't detailed in this listing.
