Why it scores 7.3.

Each part comes from the datasheet with a published rule; anything not stated scores zero.

How we rate inverters
  • Efficiency

    4.7 · 30%

    Every point of efficiency is solar you keep, every day for 10+ years.

    Rule: Maximum efficiency on the datasheet: 96% scores 0, 99% scores 10.

  • MPPTs for split roofs

    5.0 · 20%

    Each MPPT runs one roof face independently, so east and west panels don't drag each other down.

    Rule: Number of MPPT trackers: 1 scores 0, 2 scores 5, 3 or more scores 10.

  • Heat tolerance

    10.0 · 20%

    Inverters on hot walls throttle or fail early. A higher operating limit means more headroom.

    Rule: Highest operating temperature: 45°C scores 0, 60°C scores 10.

  • Room for more panels

    10.0 · 15%

    How much panel capacity the inverter accepts, so you can oversize for winter and cloudy days.

    Rule: Maximum PV input divided by rated AC output: 1.2x scores 0, 1.5x or more scores 10. Rebate rules allow panels up to 133% of the inverter, so more than 150% adds little.

  • Weather sealing

    9.0 · 15%

    Most Australian inverters live outdoors.

    Rule: IP66 or better scores 10, IP65 9, IP55 4, lower 0.
