SUN-50K-SG01HP3

Deye SUN-50K-SG01HP3 – 50 kW three-phase high-voltage hybrid inverter for larger residential and C&I systems

The Deye SUN-50K-SG01HP3 (SUN-50K-SG01HP3-EU-BM4) is a 50 kW rated, three-phase, high-voltage (HV) hybrid inverter designed for larger residential, commercial and industrial solar systems. With 4 independent MPPTs and high-voltage (160–800 V) battery support, it manages solar panels, storage and the three-phase grid in a coordinated manner. The compact, high power density design enables a 1.3 DC/AC ratio, reducing capital cost, and thanks to its IP65 protection, it can also be installed outdoors.

Why choose the Deye SUN-50K-SG01HP3 inverter?

The Deye SUN-50K-SG01HP3 inverter operates with up to 97.6% maximum and 99.9% MPPT efficiency, ensuring economical operation even at high power levels. The 4 MPPT controllers enable precise optimization of individual string performance, while the 100% asymmetric (unbalanced) output adapts to real-world, phase-varying loads. The high-voltage battery platform delivers higher system efficiency and lower thermal stress, while 6 programmable daily time periods allow the charge/discharge strategy to be tailored to tariffs and peak shaving. The inverter also supports energy storage from diesel generators and wind turbines.

Key advantages of the Deye SUN-50K-SG01HP3

• High power – 50 kW rated three-phase AC output, 55 kW max.
• 4 MPPT controllers – up to 65 kW PV input, for complex, multi-orientation arrays
• High-voltage battery support – 160–800 V, 2 battery inputs, 50+50 A charge/discharge
• 100% asymmetric output – precise adaptation to real-world, unbalanced loads
• High efficiency – up to 97.6% max. and 99.9% MPPT efficiency

• AC-coupled retrofit and generator/wind turbine support – existing solar systems can be expanded with storage
• Outdoor, wall-mounted design – IP65 protection, intelligent cooling, compact 80 kg enclosure
• Flexible communication – RS485, CAN

Applications

The Deye SUN-50K-SG01HP3 inverter is ideal for higher energy demand residential, commercial and industrial projects: large family homes, farms, factories and smaller solar parks. It is excellent for maximizing self-consumption, reducing peak demand (peak shaving) and increasing grid independence, when paired with high-voltage batteries. The built-in backup function maintains power to critical loads (motor-driven equipment, refrigerators, air conditioners, machinery) during outages, and thanks to AC-coupled expandability, existing installations can be retrofitted with storage.

Frequently asked questions about the Deye SUN-50K-SG01HP3 inverter

What does the SUN-50K-SG01HP3-EU-BM4 designation mean?
The “50K” refers to the 50 kW rated output, “SG01HP3” to the first-generation three-phase, high-voltage (HV) hybrid platform, and “BM4” to the 4 MPPT controller version.

What is the difference between the SG01HP3 and SG02HP3 platforms?
The SG01HP3 is the first-generation HV hybrid platform (typically 160–800 V battery voltage, 4 MPPTs on the 50K), while the newer SG02HP3 series offers a wider 160–1000 V battery range and more MPPTs. The choice depends on the solar array and planned battery parameters.

How many solar panels and what size battery can be connected to the SUN-50K-SG01HP3?
The inverter accepts up to 65 kW PV input across 4 MPPTs, and has two high-voltage (160–800 V) battery inputs with a total of up to 100 A charge/discharge current.

Can the Deye SUN-50K-SG01HP3 be installed outdoors?
Yes, thanks to IP65 protection and intelligent cooling, it is suitable for outdoor wall mounting, with an operating temperature range between −40 and +60 °C (with derating above 45 °C).
