Our verdict

A plain PV-only inverter for a roof with no battery planned. Its datasheet rated grid output current is 16.0A at 220V (15.7A at 230V), and a 16.0A maximum output current, so it sits on the G98 line rather than above it. Two MPPTs on a 3.6kW unit is generous for the size, and a 5.4kW recommended maximum PV input gives real headroom for a DC-oversized array. It weighs 11.2kg and the enclosure is IP66.

Good

  • Under the 16A G98 line (rated 16.0A at 220V, 15.7A at 230V; 16.0A max)
  • Two MPPTs with integrated AFCI
  • IP66, a step above the usual IP65
  • 11.2kg

Watch out

  • No battery port, so a separate AC-coupled inverter is needed to add storage later
  • Integrated DC switch is optional, not standard
  • 97.3% maximum efficiency, below the 97.7% of the 5K and 6K in the same range
