Deye SUN-20K-SG05LP3-EU-SM2 20kW - 3-phase - Hybrid LV inverter
Product specifications
Product description
The SUN-20K-SG05LP3-EU-SM2 is a three-phase hybrid inverter that combines solar energy, battery storage, and grid connection into one intelligent solution. With a maximum output power of 20 kW AC, this inverter supports both on-grid and off-grid/emergency power applications. Thanks to its two independent MPPT trackers, solar yield is maximized even with different roof orientations.
The inverter is compatible with low voltage (48 V) LiFePO₄ battery systems via RS485 / CAN communication, including:
- NKON ESS Pro series
- NKON ESS Eco series
- Pylontech US5000-1C
- Deye SE-G5.1 Pro-B
- Dyness DL5.0C
- and many more
The robust IP65 aluminum housing is suitable for both indoor and outdoor installations. Combined with NKON’s own ESS battery series, it forms a reliable and efficient solution for residential and small-scale commercial energy storage.
• Nominal output power: 20,000 W (20 kW)
