Inverter Technology Types Compared
The four main inverter technologies each suit different roof layouts, budgets, and future plans. Here is how they compare.
| Technology | Efficiency | Cost | Best For | How It Works |
|---|---|---|---|---|
| String Inverter | 96–98% | Lowest | Simple roofs without shading | Converts DC from all panels in a single string. Most cost-effective for unshaded roofs with consistent orientation. |
| Microinverter | 96–97% | Highest | 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 | 95–97% | Medium | 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 | 96–98% | Medium | 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.
Frequently Asked Questions
What is the best solar inverter in Australia in 2026?
The best solar inverter depends on your situation. For most homes, the Fronius Gen24 Plus (premium) or Sungrow SH series (value) are top choices. For shaded roofs, Enphase microinverters or Huawei with optimisers perform best. For Tesla Powerwall owners, the Tesla Inverter offers seamless integration.
String inverter vs microinverter: which is better?
String inverters cost less and work well on simple, unshaded roofs. Microinverters cost more but maximise output on shaded or complex roofs, offer panel-level monitoring, and come with 25-year warranties. For most Australian homes with clean north-facing roofs, a quality string inverter is the better value.
Do I need a hybrid inverter?
A hybrid inverter is worth considering if you plan to add a battery within the next 5 years. It costs $300 to $800 more than a standard string inverter but saves $1,000 or more when you eventually add storage, since you will not need a separate battery inverter. If you have no battery plans, a standard string inverter is fine.
How long do solar inverters last?
Most quality string and hybrid inverters last 10 to 15 years, with standard warranties of 10 years. Premium brands like Fronius and SMA often exceed 15 years. Microinverters from Enphase carry 25-year warranties and are expected to last the life of the solar system. Budget inverters may fail sooner, so warranty length matters.
What size inverter do I need for a 6.6 kW system?
In Australia, the CEC allows your panel capacity to exceed inverter capacity by up to 33%. A 5 kW inverter is the standard match for a 6.6 kW panel array. This oversizing is normal and maximises your STC rebate while the inverter clips output only during brief midday peaks.
Are Sungrow inverters any good?
Yes. Sungrow is the world’s largest inverter manufacturer and is CEC-approved for the Australian market. Their string and hybrid inverters offer strong performance at a lower price than European brands. The main trade-offs are slightly slower customer support and a less polished monitoring app compared to Fronius or Enphase.
