What is the most effective inverter in Australia to make use of in your solar power system? There are many elements and choices to think about. This article makes an attempt to present our personal opinion on the most effective solar inverters in Australia.
Please check out our methodology – we’ve tried to be very clear on the conclusion we now have reached. Important to notice that we’re simply on the lookout for the highest quality inverter on this article ignoring prices – not the most effective worth inverter. In this text we’re taking a look at residential solar so for ease of comparability we now have assessed every firm’s finest single-phase 5kW inverter mannequin.
Solar Choice’s List of the Best Solar Inverters in Australia for 2022:
Note: Solar Choice is just not an installer and has no incentive to advertise one model over one other. Be cautious of installers’ articles on the internet suggesting the manufacturers they promote are the most effective!
*Not the identical mannequin that’s accessible in Australia is marked as a prime performer, however is a sign of a top quality model
Important be aware: This rating displays the opinion of Solar Choice solely and we encourage readers to do their very own analysis and are available to their very own conclusions.

Our Methodology: How we decided the most effective solar inverters in Australia
1. Max Efficiency
The effectivity of the solar inverter is an important issue as a result of all of the DC electrical energy produced by the solar panels will move by means of the inverter to be transformed into Alternating Current (AC) which will be consumed by home home equipment.
All inverters are examined by unbiased authorities which offer a most effectivity and a ecu effectivity ranking and can show these outcomes on their product datasheet. In our comparability we now have used the utmost effectivity for an apples for apples comparability.
A solar inverter’s effectivity will fluctuate primarily based on the quantity of power that’s producing and the quantity of solar energy that’s inputted. The most effectivity is measured as the very best level within the curve the place the inverter is at its optimum efficiency.
Most solar inverters most effectivity ranges from 96.5% to 98%, with the upper being extra environment friendly.
2. Warranty
The guarantee interval can fluctuate relying on model. We suggest that you simply select an inverter with a minimal guarantee interval of no less than 5 years with 10 years being perfect.
There has been an growing variety of producers who’re providing prolonged warranties, as much as a further 20 years which often comes at a further price.
As we’ve seen many residential solar installers exit of enterprise throughout the lifetime of the solar programs they’ve put in, many end-consumers must get in contact with product producers immediately. For this motive we typically suggest you choose a model with an Australian workplace and an Australian cellphone quantity you’ll be able to name.
An extended guarantee from an organization with no Australian presence is just not value a lot in our opinion.
You can evaluate our record of CEC accepted inverter manufacturers with an Australian workplace.
3. PV Evolution Labs Top Performer
PV Evolution Labs (PVEL) has been independently testing solar panel reliability since 2014. The solar panel testing is taken into account internationally as a wonderful indication of solar panel high quality.
In 2019, PVEL launched their inaugural rating of solar inverters, which seeks to establish the highest performer solar inverter manufacturers.
Some extent to notice is that the testing course of is voluntary and the product producers need to pay to be part of it so they aren’t testing your complete market.
You can evaluate our record of PVEL Top Performers, or you’ll be able to obtain and try the PVEL 2019 Inverter Scorecard.
4. Key Features
We have seemed on the key factors of distinction that every inverter brings to the market to issue into the rating.
Notably the truth that Enphase’s resolution is micro-inverters and SolarEdge embody power optimisers has lifted them to the highest of our rating. This performance permits particular person panel degree optimisation and monitoring which provides vital worth to the tip shopper. Read extra on this right here.
Limitations of our rating
It is evident from our methodology that we now have not assessed each issue of an inverter, however need to discover a easy strategy to establish the highest quality and main solar inverter choices accessible on the Australian market.
- Costs – in the beginning as we’re contemplating the ‘best solar inverters’ for Australian market we now have ignored worth for the needs of this rating. The inverters in the direction of the highest of this rating will price greater than the choices in the direction of the underside as per the beneath indicative information:
| 5kW Inverter Option | Indicative Cost Range |
| Enphase | $2,400 to $2,600 |
| SolarEdge | $1,800 to $2,000 |
| Huawei | $1,400 to $1,600 |
| Fronius | $1,700 to $2,000 |
| SMA | $1,700 to $2,000 |
| Delta | $1,000 – $1,300 |
| Sungrow | $800 to $1,000 |
- Other inverter specs – to be able to preserve this easy we now have chosen a few of the most necessary features of an inverter to match. A extra holistic method could result in a barely completely different ordering and consequence. For instance when you’ve got 3-phase power or shading impacts in your roof, the record of doable inverters would look completely different to our rating
- Country of manufacture – for some folks this may be crucial. These days the overwhelming majority of solar gear is manufactured in China. Even European manufacturers like SolarEdge, Fronius and SMA have main manufacturing services in China. If you’re on the lookout for one thing that isn’t manufactured in China you’ll be able to take a look at the datasheet of the mannequin of inverter you might have been quoted to see the place it was manufactured.
What about manufacturers that aren’t on this rating?
These are what we’d take into account the highest 7 manufacturers in Australia for solar inverters. That doesn’t imply that manufacturers not listed on this web page gained’t do the job. There are cheaper choices from Chinese producers that may serve a buyer on a finances effectively, however you’ll have to take the danger that they might not final so long as the choices right here and should not carry out as effectively.
