As solar adoption increases across Australia, choosing the right inverter becomes critical for system efficiency and long-term savings. Among the most common options are hybrid inverters and string inverters—each offering distinct advantages depending on your energy goals. But how do you decide which one suits your setup best?
In this blog, we break down the core differences, pros and cons, and when to choose each type, helping homeowners and installers make informed decisions.
What is a String Inverter?
A string inverter is the most traditional and widely used inverter type in solar power systems. It connects multiple solar panels (in a “string”) into a single inverter that converts DC (direct current) from the panels into AC (alternating current) for household use or grid export.
Advantages of String Inverters
- Cost-effective and simple to install
- Proven and reliable technology
- Lower upfront cost compared to hybrid models
- Easy maintenance with fewer components
However, string inverters typically don’t support direct battery connection. If you want storage, you’ll need additional components—raising cost and complexity.
What is a Hybrid Inverter?
A hybrid inverter combines the functions of a traditional inverter and a battery inverter in one unit. It allows you to store excess solar energy in a battery for use later, like during nighttime or outages. Hybrid inverters manage power from both solar panels and batteries simultaneously.
Advantages of Hybrid Inverters
- Integrated battery support (great for self-consumption or off-grid)
- Smart energy management with load priority control
- Backup power support during blackouts
- Ideal for areas with time-of-use tariffs or unstable grid
On the downside, hybrid inverters generally cost more and may involve more complex installations, especially when batteries are involved.
Detailed Comparison: Hybrid vs String Inverter
To make your decision easier, here’s a side-by-side comparison of the two:
| Feature | Hybrid Inverter | String Inverter |
| Installation & Compatibility | More complex, supports both solar and battery systems | Simple setup, limited to grid-tied solar |
| Battery Support | Integrated support, ideal for energy storage | No direct battery support; needs external battery inverter |
| Efficiency | Higher overall efficiency in hybrid systems | High panel conversion efficiency but no storage |
| Cost | Higher due to combined functionality | Lower, especially for simple solar setups |
| Lifespan & Maintenance | More parts = more attention required | Fewer parts = easier maintenance |
| Use Case | Best for homes with batteries, backup needs, or TOU tariffs | Best for standard grid-tied solar without batteries |
| Popular Brands | Swatten, Deye Hybrid | Deye, Sungrow, SMA |
This table provides a quick summary of technical and practical differences based on real-world scenarios in Australia.
Hybrid Inverter: When Is It Worth It?
A hybrid solar inverter is worth the investment when:
- You want to install a solar battery either now or in the near future.
- You live in an area with time-of-use electricity pricing.
- You’re planning for energy independence or off-grid living.
- You need emergency power in case of blackouts.
Hybrid inverters are commonly used in regional or semi-rural areas in Australia, where power supply may be inconsistent or where solar rebates favour battery integration.
String Inverter: When Is It Better?
Choose a string inverter if:
- You’re only interested in exporting to the grid or self-consuming solar during the day.
- Your budget is limited and you don’t plan on battery use.
- Your system size is small to medium (residential average).
These inverters work well in metro areas with stable grids and basic solar power needs. They’re also easier to upgrade and maintain.
How Much Do They Cost?
| Inverter Type | Typical Cost (AUD) |
| Hybrid Inverter (5–6kW) | $2,500 – $4,000 |
| String Inverter (5–6kW) | $1,000 – $2,000 |
Hybrid inverter cost also depends on whether it’s AC- or DC-coupled, brand reputation, and installation complexity. Brands like Swatten and Deye offer competitive pricing for hybrid inverters.
Efficiency & Lifespan
Modern hybrid inverters offer 95%+ peak efficiency and smart control features. However, efficiency may drop slightly if batteries degrade or if systems aren’t optimally configured.
String inverters usually provide similar or slightly better panel-to-grid efficiency but lack the flexibility for energy storage.
- Hybrid inverter efficiency: Ideal for systems with batteries.
- String inverter efficiency: Ideal for simple grid-tied setups.
Top Brands & Reviews in Australia
Some of the most trusted hybrid inverter brands and string inverter suppliers in Australia include:
Hybrid Inverter Brands:
- Swatten
- Deye
- Growatt
String Inverter Brands:
- Deye
- Sungrow
- SMA
Hybrid inverter reviews often highlight smart monitoring, lower power bills, and peace of mind during outages. Meanwhile, string inverters are praised for durability and simplicity.
What Do Installers Recommend?
According to many solar inverter suppliers and installers in Australia, the decision comes down to:
- Long-term goals: Do you want battery storage later?
- Budget: How much are you ready to spend upfront?
- Energy habits: Are you often home during the day or mainly use power at night?
Tip: If you’re unsure, consult a licensed installer who can assess your energy usage and suggest the best match.
Installation Tips & Considerations
- Choose a CEC-approved inverter brand (Clean Energy Council Australia).
- Ensure your installer follows the latest AS/NZS 4777.2 standards.
- If using a hybrid inverter, plan battery location for ventilation and access.
- Use proper cabling, grounding, and isolator switch setups for safety.

Conclusion: Which One Is Right for You?
| Choose a hybrid inverter if | Choose a string inverter if |
| You’re planning to add batteries | You’re on a tight budget |
| Want energy independence | Don’t need storage |
| Need backup during outages | Prefer a simpler setup |
Both inverter types have their place. The key is to assess your energy goals and align with the system that gives the best long-term return.
