Deye SUN-12K-SG05LP3-EU-SM2 is a three-phase hybrid inverter, which combines solar power, battery storage, and grid connection in one smart solution.
With a maximum AC output power of 12 kW, this inverter supports both on-grid and off-grid / backup power applications.
Thanks to its two independent MPPT trackers, solar output 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 others

Robust IP65 aluminum casing suitable for indoor and outdoor installations.
When combined with NKON's ESS battery series, it provides a reliable and efficient solution for home and small commercial energy storage.

Our own installation company

We know our products not just from technical descriptions, but from real-world experience. Our installation company, Green Technology, builds solar power plants in the Odesa region, giving us a deep understanding of how equipment performs under actual conditions. This allows us to select and offer solutions whose reliability and effectiveness we are confident in.

32 kW solar station at a gas station in Chernomorsk.

The business now significantly reduces its electricity costs. Sunerise brand solar panels, rated at 450W and 585W, were installed. A 50 kW inverter and a 50 kWh battery from Deye were also installed.

9 kW Solar Energy System for a private house

The client wanted to eliminate electricity bills entirely, but there wasn't enough space on the house roof for all the panels. We found a solution: we designed and installed a special metal structure, enabling the owner to become completely energy independent!

9 kW station in a private house

The owner wants complete autonomy, so a 9 kW solar station was required. We installed 450W panels, an 11kW inverter, and two 15kW lithium-iron-phosphate batteries each.

Private house: 12 kW solar station

Now the client's home is fully equipped with its own electricity and does not depend on external suppliers. Another step towards an energy independent Ukraine!
