Sungrow & Fronius Solar Inverter Comparison

Before installing a solar system, it is always recommended to do preliminary research on solar panels and inverters. It is essential to know the existing brands, their specifications, performance, warranty… to make the right decision.

Installing a solar system in your home is an important decision, and it is essential to choose the right solar system since it will be there for many years, and its performance will depend on the elements you choose.

We will compare two of the best brands of solar inverters on the market. Fronius and Sungrow lead the world ranking for quality solar panel production.

We want to help you choose the right solar options available to you. And if you need more information and advice, do not hesitate to contact us.

Solar Company Background

Fronius is an Austrian battery maintenance, repair and recharging company. Fronius was one of the pioneers in 1990 and began researching and working in the world of solar energy. And this sector has since established itself as one of the most important branches of the company. Therefore, it has thirty years of experience in the sector.

Similarly, Sungrow is a Chinese company founded in 1997 as a global technology provider specialising in photovoltaic inverters and energy storage equipment for residential, commercial, industrial and utility photovoltaic power plants. It is a company oriented towards innovation and the development of renewable energies. In recent years, it has been one of the fastest-growing solar companies, and its popularity in Australia is growing rapidly.

Comparative Guide

Both brands are among the best-selling in Australia, and according to CER (Clean Energy Review), a website with professionals specialised in solar energy to advise and help consumers, the main aspects to consider when selecting a solar inverter would be the price, the warranty and the performance of the product.

Solar Inverter Price

Fronius is the brand with a higher price. It is considered the European Premium brand and is backed by its quality, high quality, and performance comes at a cost.

If you are looking for something more affordable, Sungrow has a lower price. However, comparing the quality of both inverters, the price is excellent because the inverter is of very high value when you compare the performance to the price.

There are, of course, other more affordable brands in the market, but these two brands are the ones we usually recommend because they offer the best results.

In conclusion, if you are looking for an affordable inverter without a compromised performance, you should go with Sungrow. However, if you have a bigger budget, a Fronius inverter would be the way to go.

Solar Inverter Warranty

Both brands come with a 10-year warranty.

Fronius has the advantage of a solid reputation, backed by the quality of its products, thirty years of experience, and a ten-year warranty, instilling greater confidence in the market. So you can trust that the product you buy has been around long enough to prove its long-term quality, like the company’s response to any unforeseen event.

Sungrow, although newer, demonstrates strength through its impressive performance. They are proven to offer excellent performance and have become the second largest inverter manufacturer in the world, behind only Huawei’s solar inverters.

In this case, both inverters come with the same warranty length. However, Fronius has been around long enough to prove its long-term quality and due to low failure rates and great service, it has become one of the top choices.

Conclusion: Sungrow vs. Fronius Solar Inverters – Which Is Better?

Both brands of solar inverters are a safe bet for quality and performance for your home.

Fronius is a consolidated company with years of trust behind it.

 Sungrow is a growing company that is getting better results and is gaining prestige.

The only thing that is perhaps still being taken into account is that Sungrow produces its inverters in China, and there is still some stigma around these issues, although China now makes many excellent solar products.

But without a doubt, both are in the TOP 5 of the best companies in solar inverters in the world, and either of these will be a safe bet for your solar system.
