The Deye SUN-20K-SG05LP3-EU-SM2 inverter is a high-power three-phase hybrid solution for commercial and large residential solar installations. We recommend it for facilities with high energy consumption, an unstable grid, or autonomy requirements: it provides 100% phase imbalance, generator support, and scalability up to 200 kW in a parallel configuration.

Advantages

  • Rated Power: 20 kW (max. 22 kVA)
  • Peak Off-grid Power: up to 40 kW for 10 seconds (2× rated)
  • Full Phase Imbalance: up to 10 kW on one phase (100% unbalanced load)
  • High Charge/Discharge Current: up to 350 A — suitable for industrial energy storage systems
  • Two MPPT Trackers: supports up to 32 kW DC input (2+2 strings)
  • Generator Support: ability to charge batteries from a diesel/gasoline generator
  • Scalability: up to 10 inverters in parallel (max. 200 kW)
  • Warranty: 5 years (optional — 10 years)
