Enphase IQ8 microinverters put a small inverter on every panel: best-in-class shade tolerance, panel-level monitoring, no single point of failure and a 25-year warranty. The cost is steep, adding roughly A$2,800 to A$4,000 versus a string inverter on a 6.6 kW system. Ideal for complex, shaded roofs.
Cons
- Most expensive inverter architecture per kW
- Battery ecosystem (IQ Battery) pricey in Australia
Most expensive inverter architecture per kWPros
- Per-panel MPPT: shading on one panel doesn't drag the array
- 25-year warranty, no high-voltage DC on the roof
- Excellent Enlighten monitoring app

Additional things to note about Enphase?
Enphase's disadvantage is cost: microinverters add thousands versus a string inverter, and the matching IQ Battery is among the dearest storage per kWh in Australia. On simple unshaded north-facing roofs the premium buys little extra yield.

Frequently asked questions
Are microinverters worth it in Australia?
On shaded or multi-orientation roofs, usually yes: per-panel optimisation and 25-year warranties justify the premium. On simple unshaded roofs, a quality string inverter delivers similar energy for much less.
