Deye SUN-6K-SG05LP3-EU-SM2 6kW - 3-phase - Hybrid LV inverter

The SUN-6K-SG05LP3-EU-SM2 6kW 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 6 kW AC, this inverter supports both on-grid and off-grid / emergency power applications. Thanks to its two independent MPPT trackers, solar yield is maximised even with varying roof orientations.

Compatibility

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
