The Deye SUN-8K-SG04LP3-EU inverter is a three-phase hybrid solution for residential and small commercial solar systems with the ability to connect lithium or lead-acid batteries. We recommend it for sites with unbalanced phase loads, where high peak power, overload resilience, and compatibility with existing grid infrastructure are important.

Advantages

  • Rated Power: 8 kW (max. 8.8 kW)
  • Peak Off-Grid Power: up to 16 kW for 10 seconds (2× nominal)
  • Full Phase Unbalancing: supports 100% unbalanced loads (up to 4 kW on one phase)
  • Two MPPT Trackers: supports up to 10.4 kW DC input
  • Charge/Discharge Current: up to 190 A
  • AC Coupling: compatible with existing on-grid systems
  • Scalability: up to 10 inverters in parallel
  • Warranty: 5 years (optional — 10 years)
