What is Fronius and what does it offer in solar energy?

The Fronius collection includes grid-tied inverters, GEN24 hybrid inverters with backup, smart meters, dataloggers, and electric vehicle chargers (Wattpilot). Its offering combines efficiency, granular energy control, and a professional monitoring platform to maximize system production and lifespan.

Advantages and limitations

• High European efficiencies, wide MPPT window, and optimized thermal management.
• Integrated ecosystem: Smart Meter, Datamanager, monitoring portal, and APIs.
• Hybrid models with backup functions and battery management.
• Wide range of power ratings for residential, commercial, and industrial use.
• Limitations: ventilation/space requirements may be higher than with fully sealed equipment; always check battery and grid compatibilities.

Common applications

• Residential self-consumption and SMEs with export control and advanced monitoring.
• Commercial/industrial with long strings and multiple MPPTs.
• Systems with storage (GEN24) for savings, backup, and time-based management.
• Integration with EV charging and dynamic measurement with Smart Meter.

How to choose your Fronius equipment

• Single-phase (e.g., Primo): homes with 230 V supply, low-medium power, and priority on simplicity.
• Three-phase (Symo/Tauro): businesses and industry, phase distribution, more MPPTs, and higher power.
• GEN24 Hybrid: when you need a battery now or in the future and want backup (check backup power and compatible battery type).
• Size by nominal power, PV voltage range (Voc/Vmp), number of MPPTs, input current, and protection requirements.

Best installation practices

• Check electrical and communication compatibility with the selected battery in hybrids.
• Design strings respecting Voc, Isc, and MPPT window limits with thermal margins.
• Implement appropriate DC/AC protections and isolation according to regulations.
• Ensure ventilation and free space around the equipment; follow the manufacturer's manual.
• Integrate accessories (meters, communications) to optimize self-consumption.

Quick internal comparisons

• Primo/Symo (grid): maximum simplicity and contained cost when a battery is not required.
• GEN24 (hybrid): adds battery management and backup, ideal for time-of-use tariffs.
• Tauro (industrial): designed for large PV fields with multiple MPPTs and demanding operation.
