Inverter technology types compared
String inverter
- Efficiency
- 96 to 98%
- Cost
- Lowest
Best for: Simple roofs without shading
Converts DC from all panels in a single string. Most cost-effective for unshaded roofs with consistent orientation.
Microinverter
- Efficiency
- 96 to 97%
- Cost
- Highest
Best for: Shading or complex roof layouts
One small inverter per panel. Each panel operates independently, so shading on one panel does not affect the rest.
Hybrid inverter
- Efficiency
- 95 to 97%
- Cost
- Medium
Best for: Future battery storage
A string inverter with built-in battery management. Saves the cost of a separate battery inverter when you add storage later.
Optimised string
- Efficiency
- 96 to 98%
- Cost
- Medium
Best for: Partial shading with string benefits
A string inverter paired with panel-level optimisers. Offers shade tolerance without the cost of full microinverters.
How to choose the right inverter
Single-phase or three-phase?
Most older Australian homes have single-phase power, while newer builds often have three-phase. Check your switchboard or electricity bill. If you have three-phase, choose a three-phase inverter (Fronius Gen24, SMA Tripower, or Sungrow SH 3-phase) to balance loads across all phases and avoid export limits on a single phase.
Do you have roof shading?
Trees, chimneys, or neighbouring buildings casting shadows on part of your roof reduce string inverter output significantly, because panels wired in series are limited by the weakest panel. Microinverters (Enphase IQ8+) or optimised string systems (Huawei with optimisers, SolarEdge) let each panel work independently, recovering 10 to 25% more energy on shaded roofs.
Planning a battery?
If you expect to add battery storage within the next few years, a hybrid inverter saves money long-term. The Fronius Gen24 Plus, Sungrow SH, and SolarEdge Home Hub all support battery integration without needing a separate battery inverter. This can save $1,000 or more compared to retrofitting a standard string inverter setup.
Budget vs premium
GoodWe and Sungrow offer strong value starting from around $1,000 installed. European brands like Fronius and SMA cost more but are favoured by installers for their build quality and after-sales support. For most 6.6 kW residential systems, the inverter represents 15 to 25% of total system cost, so spending an extra $500 to $1,000 on a better inverter is often worthwhile.
