This article delves into the key aspects of Fronius inverters, including their performance, reliability, features, and value proposition, to help determine if they align with your solar needs in Australia.

Fronius: A global leader in solar technology

Hailing from Austria, Fronius boasts a rich heritage dating back to 1945. They have steadily built a reputation for innovation and quality in the solar inverter space, with a global presence across 60 countries. 

In Australia, Fronius inverters are known for their reliability, efficiency, and advanced features, making them a popular choice for various solar applications.

Fronius GEN24 and BYD Battery: An All-in-One Home Energy Solution

The Fronius GEN24 inverter family offers a versatile and powerful solution who are looking to maximise their solar energy usage and achieve greater energy independence. 

One device, multiple functions

The GEN24 family combines multiple functionalities into a single unit, eliminating the need for additional hardware. It acts as a grid-connected inverter, hybrid inverter, energy management system, monitoring system, and emergency power supply. This comprehensive approach simplifies installation and streamlines your home energy system.

Flexible emergency power

Even without a battery, the GEN24 is the only non-hybrid inverter with an emergency power function called PV Point. This allows you to access essential power during outages without upfront battery investment. As your needs evolve, you can seamlessly upgrade to the GEN24 Plus and unlock full backup capabilities. 

The full backup function is only available for the Primo GEN24 Plus and the Symo GEN24 Plus 6-10 kW.

Unmatched charging and discharging

The GEN24 Plus boasts impressive charging and discharging capacities of up to 9 kW, depending on the connected battery. This enables efficient use of solar energy during peak sunlight hours and allows for quick charging of electric vehicles. Additionally, it ensures a stable power supply during emergencies.

Sustainable choice: Holds the world's first life cycle assessment

Fronius prioritises sustainability throughout the GEN24 lifecycle. The inverters are certified and tested by the renowned Fraunhofer Institute for their low environmental impact, with a CO2 payback time of less than one year up to 3.7 years, depending on the scenarios.  This means that Fronius GEN24 holds the world’s first life cycle assessment by an independent institute.

Additionally, they contribute significantly up to 16,932 kg CO2 saved over 20 years, equivalent to 9 transatlantic flights.
