Solar Inverter Types Explained: String, Hybrid and Microinverters
5 min read · Solar & Battery · Published 2026-05-28
The inverter converts solar DC to usable AC. Which type suits your roof, usage pattern and future plans makes a bigger difference than most homeowners realise.
Every solar system needs an inverter. It converts the direct current (DC) the panels produce into the alternating current (AC) your home uses. The type of inverter shapes what your system can do, how it performs under shade, and whether a battery can be added later without replacing major components.
We install solar systems with the right inverter choice through our solar and battery service, serving newer homes in Upper Coomera and growing estates in Coomera.
String inverters
The most common and cost-effective option. Panels are wired in series strings, all feeding one central inverter. The limitation is that shade or soiling on one panel reduces the output of the whole string. On a clean, unshaded north-facing roof, string inverters perform excellently and cost less than alternatives.
Hybrid inverters
A hybrid inverter manages solar panels and a battery bank together, with a single device. If you are planning to add a battery now or within a few years, starting with a hybrid inverter avoids the cost of a second device later. Most modern hybrid inverters also provide backup capability during a grid outage, depending on how the system is wired.
Tip: If a battery is on your five-year plan, a hybrid inverter now is almost always cheaper than adding an AC-coupled battery to a standard string inverter later.
Microinverters and power optimisers
Microinverters sit on each individual panel and convert DC to AC at the panel. Power optimisers are a hybrid approach: a DC optimiser at each panel feeds a central string inverter. Both approaches eliminate the shading problem because each panel operates independently. They suit complex rooflines with multiple orientations, or roofs with unavoidable shade. The per-panel hardware adds cost, but can significantly increase yield on problem roofs.
Which to choose
Clean unshaded roof with future battery plans: hybrid string. Clean unshaded roof, no battery plans: standard string. Shaded or multi-orientation roof: microinverters or optimisers. On-site assessment is the only reliable way to decide because roof geometry and shading vary too much for a general rule.
Key takeaways
- String inverters are the cost-effective default for unshaded north-facing roofs.
- Hybrid inverters suit anyone planning a battery within a few years.
- Microinverters and optimisers overcome shading but add upfront cost.
Frequently asked questions
- Can I add a battery to a system that has a standard string inverter?
- Yes, by AC-coupling a battery alongside it. It works well but adds a second inverter device. A hybrid inverter from the start is usually cleaner and cheaper overall.
- Which inverter brands do you install?
- We install reputable brands with strong Australian warranties and local service support. We recommend the right brand for your system size and budget at the quote stage.
- How quickly can FitElec attend?
- We are open 24 hours for urgent electrical work and book standard jobs within days. Call Jayson on 0425 663 172 for a current schedule.
- Where does FitElec work?
- FitElec is based at Palm Beach and services the whole Gold Coast, from Coolangatta to Coomera and everywhere in between.
