Deye SUN-125K-SG02HP3 – 125 kW three-phase high-voltage hybrid inverter for commercial and industrial systems
The Deye SUN-125K-SG02HP3 (SUN-125K-SG02HP3-EU-GM10) is a 125 kW rated, three-phase, high-voltage (HV) hybrid inverter designed for high-energy-demand commercial and industrial (C&I) systems. With 10 independent MPPTs and high-voltage battery support, it seamlessly manages solar panels, storage, and the three-phase grid – ideal for powering factories, warehouses, logistics centers, and complex solar farms. Thanks to its IP65 protection, it can be installed outdoors, and with up to 10 units in parallel, large-scale systems can be built.
Why choose the Deye SUN-125K-SG02HP3 inverter?
The Deye SUN-125K-SG02HP3 inverter operates with up to 98.7% maximum efficiency, ensuring economical operation even at high power. The 10 MPPT controllers enable precise optimization of individual string performance, which is particularly important for large solar arrays with different orientations. The 100% asymmetric (unbalanced) output adapts to real industrial loads where individual phase loads can differ significantly, and the UPS function ensures seamless switchover in case of grid failure. With 6 programmable daily time periods, the charge/discharge strategy can be tailored to tariffs, peak shaving, or aggregator cooperation.
