The Deye SUN-20K-SG05LP3-EU-SM2 is a 20kW three-phase low-voltage hybrid solar inverter designed for large residential, commercial, and high-demand applications.
The Deye SUN-20K-SG05LP3-EU-SM2 is a high-capacity 20kW three-phase hybrid inverter designed for demanding solar energy systems. It combines solar PV, low-voltage battery storage, grid electricity, and generator input in a single energy management solution.
Solar energy can power connected loads during the day while excess generation is stored in the battery for nighttime use or backup during grid outages. Advanced MPPT technology helps maximize solar production, while intelligent battery management ensures efficient charging and discharging.
Its three-phase output makes it suitable for large homes, offices, hotels, commercial buildings, workshops, and other properties with three-phase electrical systems.
Using LONGi Hi-MO 7 615W bifacial panels:
| Usage | Panels | PV Capacity |
|---|---|---|
| Basic Daytime Use | 32 | 19.68kWp |
| Heavy Daytime Use | 40 | 24.60kWp |
Basic daytime use: Suitable for large homes and businesses with moderate daytime consumption.
Heavy daytime use: Recommended for multiple ACs, commercial refrigeration, pumps, hotels, offices, workshops and other high daytime loads.
Final panel quantity and string configuration must be verified against the inverter's maximum PV input power, MPPT voltage range, maximum PV voltage and current limits.
