What to Look for when Choosing a Solar Power Inverter
In our experience over the years and as thousands of residents across the Gold Coast and the nation can now testify to, a warranty may look good on paper but if the company who are offering that warranty are no longer around when there’s a problem then it’s not worth the paper it’s written on. If that’s the case it’s therefore very important to look at the companies behind the solar power inverter your looking at buying.
Of course we don’t have a crystal ball to see into the future but we can make an educated decision by looking at the company behind the solar power inverter to get a good idea whether they could disappear like the manufacturers of other inverters have. Here are the top inverter manufacturers we recommend and why.
The Solar Power Inverters We Recommend
Fronius – At Gold Coast Solar Power Solutions we recommend Fronius solar power inverters as the very best solar string inverters on the market. As a leader in the solar inverter field Fronius is a highly reputable, established, European company (Austrian) with a history that spans over 70 years.
With industry leading technology and innovation ensuring the highest solar power production and the greatest system up time and convenience for you – the solar power system owner.
Gold Coast Solar Power Solutions have been a service partner with Fronius since 2008 and over that time we have found Fronius to be the very best in the industry when it comes to dealing with warranty issues; in fact if you have a Fronius warranty issue we can usually get your solar power system back in operation within a couple of days, which is a lot better than the couple of weeks or even months with many other solar inverter companies!
10 Year Warranty on Fronius Inverters
Until the 31st of December 2016 all Fronius inverters come with an extended 10 year warranty, that’s 10 years peace of mind.
If your inverter is a 1.5, 2, 2.5 or 3 kW the Fronius Galvo range is a great replacement model as it is a “transformer” type of inverter whereas most other replacement inverters are transformerless types which may require some extra work to ensure your solar power system is safe.

Zeversolar – If you are after a cheaper but still good quality product we recommend the Zeversolar range of solar inverters. Zeversolar is a Chinese company which is part owned by SMA (see below), this has allowed Zeversolar to combine the best of two worlds: Chinese efficiency and German quality standards. Zeversolar solar power inverters are available in the following sizes:
Please note – all Zeversolar solar inverters are of a “transformerless topology” and this means that any solar power system that these inverters are connected to should have the solar panels and framing bonded to earth out to eliminate the possibility of electric shocks. If your solar panels and framing system are not earthed they will need to be if you are installing this inverter.

Zeversolar solar power inverters come with a 5 year warranty as standard.
SMA – SMA inverters are industry leading inverters with all the SMA solar power inverters sold in Australia coming from SMA’s state of the art production line in Germany. SMA are represented on four continents, have a staff of over 5,500 and an annual turnover in 2012 of EUR 1.5 billion. Each year they spend millions of Euros on research and development to ensure their products remain the very best in the industry. SMA inverters come standard with a 5 year warranty which can be extended if required; in Australia this warranty is backed up by a team of engineers based in SMA’s Sydney office.
Power-One Aurora – Power-One Aurora inverters sold in Australia are made in Italy with the company recently being bought out by the ABB group. The ABB Group is a multinational corporation that is one of the largest engineering companies as well as one of the largest conglomerates in the world. They have operations in around 100 countries and employ approximately 145,000 people around the world with a global revenue in 2011 of $40 billion. When choosing a Power-One Aurora solar power inverter that is covered by the ABB Group umbrella you can be quietly confident that the manufacturer is going to be around in the future to honour their warranties. Standard residential Power-One Aurora inverters come standard with a 5 year warranty which can be extended if required, whilst the larger 3 phase commercial Power-One Aurora inverters come standard with a 10 year warranty.
