Our read of the datasheet

This is the 5 kW single-phase member of EcoFlow's PowerOcean range, which also includes 3 kW and 6 kW versions. The 11 kW maximum PV input is 220% of the AC rating, which leaves plenty of room to oversize the array, and two MPPTs handle a two-face roof.

It works with EcoFlow's high-voltage PowerOcean LFP packs of 5.1 kWh each, up to 20.4 kWh per inverter, and up to three inverters can be cascaded for 60 kWh. The backup load port is rated at 5 kVA, but the datasheet does not give a switchover time.

EcoFlow quotes efficiency only as greater than 96.5% peak and greater than 96% European weighted, at the lower end of this group. The datasheet states a 15-year warranty.

We have not tested this inverter. This summary follows from the manufacturer's published specifications, checked 23 September 2026.

Strengths

  • 220% PV oversizing headroom (11 kW on 5 kW AC)
  • 15-year warranty stated on the datasheet
  • Scales to 20.4 kWh per inverter, or 60 kWh with three cascaded

Things to check

  • Efficiency quoted only as greater than 96.5%, lower than most rivals here
  • No backup switchover time given
  • Battery choice limited to EcoFlow PowerOcean packs
