Deye SUN-75K-SG02HP3-EU-EM6 — a high-tech hybrid three-phase inverter designed for industrial and commercial solar power plants. The device belongs to the Deye HP3-EU EM6 series of high-voltage models, which supports operation in both grid-connected and off-grid modes with LiFePO₄ batteries. Its maximum efficiency is 97.6%, making it one of the most efficient in its class.
The inverter is equipped with a high-voltage lithium-ion battery interface (160– 1000 V), supports parallel operation of up to 10 units in a system (both on-grid and off-grid), and features a powerful bidirectional charge/discharge circuit with a maximum current of 80 A. This allows it to function as the main node of an energy storage system (ESS) at facilities requiring high power supply stability, as well as in microgrids or hybrid stations with generators.
Key Benefits
- 100% asymmetric output — each phase operates independently, allowing load balancing in three-phase systems without power loss.
- AC pair for retrofitting — enables integration of the inverter into an existing solar system without the need for a complete reconfiguration.
- Parallel operation of up to 10 inverters — system scalability up to 750 kW, with support for the simultaneous operation of multiple battery banks.
- High-voltage battery interface — increased energy transfer efficiency and lower losses during charging/discharging.
- Maximum charge/discharge current — 80 A, ensuring rapid energy storage and delivery in the battery system.
- Six charging/discharging periods — flexible planning of energy flows according to tariff zones or plant operating modes.
- Diesel generator backup power — for uninterrupted power supply to critical loads in the event of a grid outage.
- Integrated BMS communication — full self-adaptation to battery management systems (BMS) without additional programming.
- Type II protection for DC and AC — bidirectional protection against surge voltages and lightning strikes.
- Intelligent air cooling — stable operation at temperatures from -40 to +60 °C with derating above 45 °C.

Design and Safety Features
The inverter housing has an IP65 protection rating and is resistant to dust, moisture, and temperature fluctuations. The built-in “smart cooling” system adaptively adjusts the airflow speed, allowing for effective cooling of the power modules even when operating at full power. Noise level ≤ 65 dB — suitable for installation in both technical rooms and outdoors.
The inverter features built-in multi-level protections: against short circuits, overvoltage, overload, overheating, reverse polarity, current leakage, and “islanding” mode (anti-islanding). Separately implemented DC circuit insulation monitoring, residual current detection (RCD), and an AFD system—arc fault detection (optional). These technologies meet the requirements of IEC and VDE standards for industrial inverters.
Applications
- Industrial and commercial hybrid solar power plants with energy storage systems (ESS).
- Facilities requiring backup power: hospitals, warehouses, data centers, agricultural enterprises.
- Microgrids with generators or diesel sets (VSG / Generator Support mode).
- Smart Grid systems with zero energy export (Zero Export).
- Large facilities requiring phase balancing and handling asymmetric loads.
