Fronius Solar Inverter

In this Fronius solar inverter review, we will highlight all the aspects of this famous inverter brand. The detailed review will tell you why the Fronius solar inverters are worth the investment. 

Solar inverters are an essential piece of solar power systems as it plays a pivotal role in maximising the efficiency of the solar panels. Thus, selecting the best solar inverter is a must. Fronius solar inverters are one of the best solar inverters available in the solar industry. 

The work of a solar inverter is simple but essential. Solar inverters convert the DC electricity that the solar panels produce by absorbing energy from the sunlight into AC electricity. The AC electricity is then used to power the appliances in the household. 

Before discussing the features of the Fronius solar inverters, let us look at the company’s history. 

Fronius is an international company founded on 20th June 1945 in Austria. Fronius has a history of manufacturing welding equipment for over 75 years now. And the company has experience of nearly three decades in manufacturing solar inverters, battery chargers, and other monitoring and energy controlling devices. 

The grid-connected Fronius solar inverter made its first appearance back in the year 1995. The company has grown to be one of the best solar inverter manufacturers in the solar market since its first appearance. Fronius has 28 offices all over the world, and out of these 28 offices, 19 are associated with solar energy. Fronius also has an Australian office situated in Tullamarine, Victoria. 

Where are Fronius solar inverters manufactured?

Fronius solar inverters entered the Australian solar market in 2010, and since then, the company has installed more than half a million solar inverters in Australia. Fronius solar inverters are ideal for both commercial and residential solar projects.

Are Fronius solar inverters any good?

Fronius solar inverters are one of the best solar inverters out there. Below mentioned are some features of the Fronius solar inverters that make them the ideal solar inverter for your home. 

  • Efficiency:

Generally, the efficiency standard of residential inverters ranges between 95 to 98 per cent. The efficiency of the Fronius Primo and Symo is equal to or more than 98 per cent ranking them at the top tier of residential inverter efficiency. 

  • Warranty:

All the Clean Energy Council Fronius solar inverters available in Australia come with a product warranty of five years. Homeowners can claim a free product warranty extension for five more years by registering through Fronius Solar.Web within 30 months of purchase. 

The first five years of the product warranty will cover the cost of the parts and the labour. The extended five years will only cover the cost of the parts. Homeowners can also purchase an extended product warranty of 5, 10, 15, 20 or even 25 years from their solar installer. 

  • Monitoring:

All the Fronius solar inverters come with Wi-Fi monitoring via the Fronius Solar.Web. The intelligent monitoring system allows homeowners to carefully monitor the energy generation of the solar power system and the energy consumption of their homes. The Solar.Web is a free smartphone app available for both android and iOS. 

  • Temperature Control:

The built-in fan is a key feature in the Fronius solar inverters. Every electric appliance heats up, and Fronius solar inverter is no different. The heat of the appliance causes a decrease in efficiency. In order to fix this issue, Fronius installed a fan in its solar inverter to cool down the inverter when it heats up. This cooling system of the Fronius solar inverters extends its lifespan and prevents rapid degradation in efficiency. 

The only downside of the built-in fan in the Fronius solar inverter is the noise. The noise of the fan makes the Fronius solar inverters a bit louder compared to the other inverters. However, this will not cause any sort of disturbance to the homeowners unless they install the solar inverter in the living room or near the bedroom. 

How much is a Fronius inverter?

The Fronius solar inverters are manufactured in Austria and are a bit expensive than other available solar inverters in Australia. The Fronius inverters are costly as they offer better quality than other Chinese solar inverter brands. While the higher price tag is a concern, the fact is that you get what you pay for. The outstanding performance and quality of the Fronius solar inverters make the inverters worth the cost.

Battery storage is an essential investment for homeowners who are looking for a way to get the most of their solar power systems. Storing the excess energy produced by the solar panels during the day helps to save the money of importing electricity from the mains grid.

If you want to install battery storage to store energy, consider installing a Fronius hybrid inverter. If you want to install battery storage later or want to install one with your existing Fronius solar inverter, then you can easily do it.
