Description

The Deye SUN-12K-SG04LP3 is one of the best-selling  three-phase hybrid inverters, trusted for its outstanding stability and long-term performance. It’s designed for advanced solar energy systems in residential and small commercial use. The inverter supports both on-grid and off-grid modes, integrates with diesel generators, and enables high-efficiency lithium battery storage. Ideal for retrofits and new installations.

Key Features & Benefits

  • 100% unbalanced output: Each phase supports up to 50% of rated power – ideal for homes with uneven loads.

  • AC-coupling retrofit support: Easily upgrade existing solar systems with hybrid functionality.

  • Scalable system: Up to 10 inverters in parallel (grid-tied or off-grid) with multiple battery bank support.

  • Max. charge/discharge current: 240A – optimized for high-capacity energy storage systems.

  • Diesel generator compatibility: Hybrid system can intelligently coordinate with a genset.

  • 6 configurable time slots for smart battery charge/discharge scheduling.

  • 48V low-voltage battery support with transformer isolation for extra safety.

  • 2 MPPTs, wide PV input, smart EMS, WiFi monitoring, RS485 & CAN communication.

Perfect for: 12kW solar setups, hybrid retrofits, off-grid cabins, battery-first configurations, and German/EU grid-compliant systems.
