The Deye SUN-12K-SG05LP3-EU-SM2 is a three-phase hybrid inverter that combines solar energy, battery storage, and grid connection in one intelligent solution.
With a maximum output power of 12 kW AC, this inverter supports both on-grid and off-grid / backup power applications.
Thanks to its two independent MPPT trackers, solar yield is maximized even under 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 indoor and outdoor installations.
When combined with NKON’s ESS battery series, it provides a reliable and efficient solution for residential and small commercial energy storage.
