Why it scores 8.5.

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

How we rate inverters

Efficiency
8.3 · 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
10.0 · 15%
Most Australian inverters live outdoors.
Rule: IP66 or better scores 10, IP65 9, IP55 4, lower 0.

About the brand

SolaX inverters

Strong specs, a long local presence and a clean recall record for its own inverters. Installers don't often pick it for themselves, but there's little to fault on paper.
