Why it scores 8.9.

Rated on 7–10.5KTLM-G3, its best home version. Each part comes from the datasheet with a published rule; anything not stated scores zero.

How we rate inverters

Efficiency
7.0 · 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
10.0 · 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.

About the brand

Sofar inverters

Decent budget inverters that are growing fast, with local support. Its 2018 compliance problems are long past but worth knowing, and installers rarely pick it for their own homes.
