Many say yes, and some say no. However, it’s 2024, and a decade of innovation has passed since the launch of the acclaimed Fronius snap-inverter range. An iconic inverter suite, catapulting Fronius’s success in Australia. With a vast improvement in all electronic products manufactured globally, an often confronting question arises when exploring a solar energy investment, “is a Fronius inverter worth the additional expense?”. Although, a more modern perspective exists to determine a Fronius inverter’s suitability and value. Consider the ecosystem.


Key points

The modern energy ecosystem is where energy control harmonises and comes together as one. Each dwelling within Australia is about to form its own over the new decade.

The useability and effectiveness of this energy ecosystem reflect the product selection along the journey. Consider the solar inverter the foundation of your new energy ecosystem. Like any new building, constructing an energy system with a stable foundation is essential.

With an excellent reputation, incorporating a Fronius inverter as the foundation of a solar energy system is considered by many an astute move. However, an energy system is more than just solar in 2024. It’s an ecosystem, and additional consideration of the Fronius inverters associated peripherals should be considered at the same time.

Which to consider

Ensuring the ideal foundation for your new energy ecosystem means selecting the precise Fronius inverter. Power supply to the premises defines your Fronius inverter model in most instances. Single-phase power supplies consider Primo branded Fronius inverters. Three-phase dwellings have the expanded offering of the Fronius Symo inverter models catering towards increased power demands.

Fronius Primo GEN24: Due to grid limitations, Perth, Western Australia (region) is limited to single-phase inverter sizes no greater than 5 kW output. Therefore, the 5 kW Fronius Primo GEN24 is an ideal single-phase solution capable of handling up to 9.9 kW of solar panels when paired with a BYD HVM DC-coupled battery. A handy trick if a 6.6 kW solar array is a tad shy of the power you desire.

Fronius Symo GEN24: Three-phase hybrid solar and battery inverters are gaining rapid appeal. The Symo GEN24 is your Fronius inverter of choice if increased battery connectivity options constitute a significant preference. Although, due to the often cumbersome nature of hybrid inverters, it’s unlikely to see power classes greater than 10 kW.

Fronius Symo: The proven Fronius inverter for most three-phase power supplies. Fronius Symo inverters provide added field assurance with over a decade of successful implementation in Australia. A solar-only model, the Symo retains an onboard display for localised production and state interpretations as an ideal solution for dwellings with limited internet connectivity. As with all Fronius inverters, AC-coupled batteries are compatible.


GEN24 or GEN24Plus? Save your money. Unless integrating the BYD HVM battery simultaneously with the solar energy system, there are limited reasons to invest in a Fronius GEN24PLUS model initially. Converting the GEN24 (non-plus) model to a GEN24PLUS after installation is easy. It’s a (paid) firmware update activated within your Fronius Solar.web monitoring portal, referred to as FroniusUP. If implementing the BYD battery in the future, simply activate this feature. Doing so reduces the initial system cost and ensures no wasted capital if the battery isn’t required.

Smart Meter: Opening up Solar.web for the first time without a Fronius Smart Meter installed feels a little underwhelming. Installed in line with your energy supply point, this device monitors excess solar energy exported to the grid while delivering real-time energy consumption information fulling in the gaps related to your general energy profile. Understanding your energy profile how you produce and consume energy is the key to bill reduction success.

In addition, your alternative Fronius ecosystem devices require the signalling information provided by the Fronius Smart Meter to work to their potential. The Fronius Smart Meter should be considered an essential tool when buying a Fronius inverter powered energy system. 

Wattpilot: A standard electric vehicle charger. However, when incorporated alongside a Fronius inverter power energy system and Fronius Smart Meter, the Wattpilot’s full capabilities are realised. Ensure your car is charged entirely from the sun or low-cost grid energy with various modes. Your vehicle becomes an extension of your energy system. Shop Wattpilot →

Ohmpilot: Use your storage electric hot water unit as an intelligent energy storage system. Depending on your set preferences, divert excess solar energy, not being consumed within the premises, to the heating of stored hot water for later use. Rinse and repeat: Re-heat water the following day with excess sun energy.

Solar.web:  Where your Fronius inverter infused energy profile comes together for detailed energy visualisation, system diagnostics, service messages, service alarms, beneficial data and expanded energy control. An online web portal, access your solar.web from a desktop browser or Android and iOS smart devices. To ensure solar.web provides reliable energy insight, a stable LAN or WiFi connection is required to your Fronius inverter at all times. 

With a deeper understanding of the Fronius inverter powered ecosystem, certain features will instantly appeal, while others maybe not as much depending on your appliances. Nonetheless, it’s vital to keep exploring certain attributes of the Fronius inverter type and size better to understand value (cost vs benefit over time)…
