Deye GB-S12K-EU Hybrid Inverter 12kW Three-Phase High Voltage All-in-One
The Deye GB-S12K-EU is the 12kW three-phase hybrid inverter of Deye's high-voltage all-in-one storage system: it handles up to 15.6kW of PV on 2 MPPTs and a high-voltage battery pack in the 160-700V range, built from stackable Deye GB-L modules and the GB-LB control box. It suits three-phase homes, shops and small businesses that want self-consumption, storage and backup in a single cabinet.
The high-voltage design keeps currents low and cuts cable losses: peak efficiency is 97.6% with 99.9% MPPT efficiency. The generator input and unbalanced output up to 25A make it a good fit for weak grids, while CAN communication with the BMS and the CEI 0-21 compliance declared by Deye make installation in Italy straightforward.
