Best Solar Inverter Brands

Share This Post

A solar array is never complete without a solar inverter. However, some brands are more trusted than others. There are a lot of solar inverter brands to choose from, so it can be hard to figure out which is the best if you’re unfamiliar with the Australian solar landscape.

With more than a decade of experience in solar panel and inverter installation, I’ve learned that not all solar inverters are equal. There are some stand-out brands on the Australian market that will offer you the best performance and reliability for your solar PV system. 

This article will look at the top solar inverter brands in Australia, giving you a rundown of which models are available. I’ve also included some background on each brand, any unique features they offer, and what kind of warranty you’ll get when buying a solar inverter. 

The best solar inverter brands in Australia are Fronius, SMA, Q CELLS, SolarEdge, Enphase, Sungrow, GoodWe, and Huawei. Each brand has unique features, pros, and cons that will suit different solar PV system requirements. 

Although each has a competitive advantage, the best solar inverter brand for one is not necessarily the best for another. It’s always best to speak to your solar installation company about which solar inverter you need to ensure it’s the right solution for your solar PV system overall. 

However, to give you some guidance, this article will cover the top solar inverter brands in Australia and provide information on choosing the best solar inverter for you. 

Let’s get started!

Why Do I Need a Solar Panel Inverter?

Homeowners and businesses need a solar panel inverter for their solar system to make the energy they get from the sun usable. An inverter transforms direct current (DC) from your solar array to alternating current (AC), which is used to power your home or business. 

Solar panels generate direct current (DC) electricity, which is a steady one-directional flow of electric charge. An inverter is an apparatus that converts DC electricity to alternating current (AC) electricity. AC electricity flows in two directions in the power system’s circuitry, changing from positive to negative charge. This allows the inverter to control electrical flow. 

Most home appliances sold in Australia use AC electricity to operate properly. Without an inverter, you cannot convert the DC output from your solar array to the AC requirement of your appliances, machines, or gadgets. This means the energy generated by solar panels is useless without a solar inverter. 

At the beginning of their solar journey, many Australians don’t know what a solar inverter is or what role it plays. However, using solar panels to power your home is impossible without an inverter. This technology is critical, and choosing the right solar inverter is key to getting the best performance from your solar PV system. 

Because an inverter is an integral part of a solar power system, you’ll need the right one for your array. But with all those brands in the market, doing so can be quite challenging.

We have made a comprehensive guide of what we think are the best solar inverters in Australia, including specifications and details for each brand or model.

How Do I Choose the Right Solar Inverter?

Technically speaking, installers will help you choose the right solar inverter by considering your existing solar array, geography, and site conditions. On top of that, there are more preferential criteria like your budget and which brand you’re comfortable with.

Let’s break down these criteria.

1. Your Solar Array

The general rule of thumb is that the rating of your solar system should match the rating of your inverter. However, it’s common to oversize your solar array within a ratio of 1.33 to keep your PV system running at maximum efficiency – for instance, installing a 5kW inverter for 6.6kW of solar panels. 

Making sure your inverter suits your solar PV system size is the most important factor to consider. You should also speak to your solar installer about future plans, like expanding your solar array.

2. Your Geography

The location of your solar array also impacts your choice of solar inverters. Let’s say you live in a place where it’s sunny most of the time. Your 6-kilowatt solar array system will generate more power for your home than a similar array in an area with more clouds or shade. 

Due to the different levels of generated DC electricity, your inverter should be able to handle that load. Thus, if you live in a sunny area, your inverter’s output would be closer to your solar array wattage. But if you live in an area that does not receive too much solar radiation, you might need to install an inverter of lesser maximum output than your solar array’s wattage.

3. Site-Specific Conditions

The site of the inverter is also something that you need to consider. Terrain features, environmental conditions, the location of your array, and the design specifics of your solar array must all be considered when choosing the right solar inverter. 

Key factors include your solar system’s positioning, orientation, angle, and tilt. Thus, the capacity of your ideal solar inverter may be slightly higher or lower than your solar array’s actual wattage. Professional installers will note all these factors to help you choose your inverter.

4. Type of Inverter

Your purpose can help determine the type of inverter you need. For instance, residential areas can only use microinverters or string inverters, while larger regions call for central inverters.

Additionally, your preferred design or look can also help you decide on a suitable inverter. For example, microinverters are highly flexible in design and can deal with overshadowing.

5. Budget and Brand

Of course, budget is always a consideration when choosing something. Luckily, you have many choices, since affordable converters don’t necessarily mean bad-performing ones. You can see a range of reputable brands that perform well on our list below.

What Are the Different Types of Solar Inverters? 

There are different solar inverters: string inverters, string + optimisers, microinverters, central inverters, and hybrid inverters. They can be categorised into grid-tie inverters, off-grid or standalone inverters, and hybrid inverters.

Knowing these types and their features can help you decide which one is best for your home or business. Once you have an understanding of how a solar inverter works, you’ll be able to better 

Here are the three grid-tied solar inverters you need to know:


As their name implies, microinverters are inverters for solar power systems designed for residential and small-scale commercial use. Usually, each microinverter is installed in an individual solar panel, which eliminates the need to install a separate inverter.

Categorised as module-level power electronics (MLPE), microinverters convert DC to AC by attaching to a single solar panel. They have lower power ratings but higher overall costs.

Because of the way micro inverters are set, if one of the panels is shaded or malfunctions, the system will still work, albeit at a slightly lower efficiency level. The other inverters can still convert DC power generated from the other solar panels to AC. In addition, you can check the performance level of each solar panel. 

Micro inverters are still considered recent technology. Thus, they’re generally more costly than their counterparts. This is offset by increased and more independent energy generation.

Pros of Micro Inverters

The advantages of micro inverters include:

  • Maximum control due to its panel-level MPPT (maximum power point tracking)
  • Highly reliable because of its MPPT
  • Increased system availability as one broken solar panel will not compromise the entire solar system
  • Specificity in monitoring, which is helpful for repair and maintenance
  • Lower DC voltage, which makes it safer than other types
  • Flexible enough not to suffer from sites that get plenty of shadows
  • Design can be simpler and more flexible
  • Allows the use of different models of makes, which is good for repairs and upgrades

Cons of Micro Inverters

The disadvantages of micro-inverters include: 

  • Comparatively expensive
  • More complex installations can lead to higher installation costs
  • Some brands have issues in extreme heat
  • Higher maintenance costs

String Inverters

String inverters are classic types of inverters that have been used for a long time for residential and commercial applications. String inverters convert DC to AC by connecting to multiple solar panels. In this setup, the solar panel arrays are arranged into rows or groups, forming a “string.” The string is then connected to an inverter specifically for that purpose.

Pros of String Inverters

The advantages of string inverters include:

  • Highly efficient
  • Low-cost
  • Works great in direct sunlight
  • Robust
  • Has three phase variations
  • Has remote system monitoring capabilities
  • Offers some design flexibility
  • Well-supported

Cons of String Inverters

The disadvantages of string inverters include:

  • No panel-level MPPT (maximum power point tracking)
  • No panel-level monitoring
  • Poses a safety hazard because of their high voltage

Central Inverters

As its name implies, a central inverter concentrates electrical power in a single place. Central inverters operate like a massive string inverter. They convert DC to AC by depending on single-stage power conversion. 

Universally, these inverters are large, use long wires, and convert a massive amount of power per solar array unit. They are most often used in industrial applications, buildings, field installations, and other large applications.

Sometimes, string inverters connected to a group of panels are linked together with a recombiner. Recombiners consolidate the output from the stringed arrays and feed them into the central inverter.

Pros of Central Inverters

The advantages of central inverters include:

  • They’re highly efficient, making them an excellent long-term investment 
  • They have a comparatively lower price per watt 
  • A fast installation process will mean your solar technicians will have it up and running sooner

Cons of Central Inverters

The disadvantages of central inverters include:

  • The systems are fairly large, which can compromise aesthetic design
  • These units can be noisy, which may be a deterrent for some 
  • The entire system may fail because of a single point

How Much Do Solar Inverters Cost in Australia? 

Solar inverters can vary widely in cost depending on maximum output, size, brand, and other factors. One major factor in the cost of solar inverters is their size, which is rated in kilowatts or kW; the higher the kW, the higher the price.

Let’s compare the more affordable Sungrow as our base, with the most expensive brand Enphase as our ceiling.

For 5 kW inverters, you’re looking at anywhere from $800 (Sungrow) to  $2,600 (Enphase). For 10 kW inverters, it’s somewhere between $2,500 (Sungrow) to $13,500 (Enphase). For 15 kW, it’s more or less $3,000 (Sungrow) to $20,000 (Enphase). For 20 kW, it ranges from $3,000 (Sungrow) to $26,000 (Enphase).

What Do Solar Inverter Warranties Cover? 

The coverage of solar inverter warranties varies depending on the manufacturer and product. For most manufacturers, parts and labour are covered. Check the fine print or clarify with your supplier to be sure.

Like many other devices and electronics, solar inverter brands are covered with a warranty. What is covered depends on the brand, as warranty coverage can vary from manufacturer to manufacturer.

In general:

  • The inverter itself is covered from 5 to 25 years
  • Power optimisers for string inverters can have up to 25-year coverage
  • Extended warranties are not included but can be purchased as an option
  • Labour costs and workmanship are not typically covered
  • Shipping of replacement parts is usually covered
  • Exceptions, limitations, and warranty fulfilment depend on the terms & conditions 

It’s best to ask the brand for more specific details regarding the warranty for the solar inverter that you bought and installed.

Related Questions

Do All Solar Panels Need Solar Panel Inverters? 

Yes, all solar panels need inverters. The primary role of an inverter is to convert the current flow of your solar panel, which is DC or Direct Current, to the current flow used by your appliances, which is AC or Alternating Current. Without inverters, you cannot use solar energy to power your appliances at home.

Can I Install a Solar Panel Inverter Myself? 

It’s best to leave the installation of solar panel systems and inverters to professionals. Like working on high-voltage electrical components, installing solar panel inverters requires a high degree of expertise and know-how. Consequences of improper installation range from voiding your warranty and inefficient functioning to inverter failure and personal injury. 

What is a Hybrid Solar Inverter? 

A hybrid solar inverter converts DC to AC just like any other converter. However, it can also reverse-send extra DC power back to the battery for storage. This stored energy can be used when you need more power. Alternatively, the extra power could be routed and sold back to the local grid.

You can have a hybrid inverter directly integrated into your solar battery. This way, you can easily monitor your solar array’s energy output.

What is the Most Expensive Solar Inverter Brand?

The most expensive solar inverter brand in Australia is the microinverter company Enphase. The same 20-piece 345 W panel setup would cost $10,309 with Enphase inverters, while it is lower by almost $100 and $700 with SolarEdge and SMA inverters, respectively.
