The Deye SUN-50K-SG01HP3-EU-BM4 is a high-power 50 kW three-phase hybrid inverter designed for demanding residential, multi-unit and small C&I PV systems that require high-voltage (HV) battery storage, robust load handling, and flexible system design. With 4 MPPT (8 strings) and 2 HV battery inputs, it is an excellent platform for building scalable hybrid systems that maximize self-consumption, enable time-of-use (TOU) strategies, and provide reliable backup/off-grid operation when configured accordingly.

Why installers choose it

• High-voltage battery platform (160–800 V): higher efficiency and lower currents for large ESS builds

• 2× HV battery inputs (50 A + 50 A): strong charge/discharge capability and flexible battery integration

• 4 MPPT / 8 strings (2+2+2+2): ideal for multiple roof orientations, larger arrays, and partial shading

• 100% unbalanced output: better tolerance for real-world three-phase loads

• Parallel scalability: up to 10 units in parallel for higher power or multi-inverter projects (on-grid/off-grid)

• Smart energy control: up to 6 time periods for battery scheduling + generator support (site dependent)
