The Deye SUN-12K-SG05LP3-EU-SM2 inverter is a powerful three-phase hybrid solution for large residential and small commercial solar installations. We recommend it for facilities with high energy consumption and a need for autonomy: it provides high peak power, supports unbalanced loads, and is compatible with existing PV systems (AC/DC coupling).

Advantages

  • Rated power: 12 kW (max. 13.2 kW)
  • Off-grid peak power: up to 24 kW for 10 seconds (2× nominal)
  • Full phase imbalance: up to 6 kW on one phase (100% unbalanced load)
  • Two MPPT trackers: supports up to 15.6 kW DC input
  • Charge/discharge current: up to 240 A
  • Generator support: ability to charge from a diesel or gasoline generator
  • Scalability: up to 10 inverters in parallel
  • Warranty: 5 years (optional — 10 years)
