Solar inverter repairs: When to DIY and when to call the pros
Founded in Austria in 1945, Fronius has evolved from a regional welding equipment manufacturer into one of the world's leading solar inverter producers. Fronius launched its first grid-connected solar inverter back in 1995. Since then Fronius has grown to become one of the industry leading solar inverter manufacturers, with 19 of 28 offices worldwide being involved with solar energy. Today, Fronius is highly regarded in the solar world and is generally considered the world's leading string solar inverter manufacturer. This reputation is not based on sales volume, but on service, quality and, most importantly, reliability.

🏭 Austrian Engineering Excellence
All Fronius solar inverters are engineered, designed and manufactured in Austria. With over half a century of experience in inverter (welder) design and manufacturing, it's not surprising Fronius is considered an industry leader in power conversion equipment.
⚡ Industry-Leading Reliability
In the 2024 SQ Installers' Choice Awards, Fronius achieved the top spot for the fourth year in a row - and quite convincingly. In regards to service, Fronius has ranked very highly for many years due to the low failure rates and great service. If a failure occurs, they usually ship replacement units in 3-5 business days.
🔧 SnapINverter Technology
A unique aspect of Fronius inverters is the SnapINverter technology. It's a standardised wall-mounted bracket with the inverter on a hinge system. This revolutionary design makes installation and servicing remarkably simple for certified installers.
📱 Advanced Monitoring
Fronius inverters offer advanced monitoring capabilities, allowing real-time access to energy production and system status through mobile apps and web portals. This data empowers users to detect and resolve issues promptly, optimise energy usage, and integrate with smart home systems and energy management platforms for more efficient energy consumption.
The flagship fronius gen24 plus hybrid inverter represents Fronius's vision of '24 hours of sun'. This innovative model offers unique PV Point functionality, providing backup power up to 3kW during daylight hours without requiring battery storage. The system seamlessly integrates with BYD battery solutions for complete energy independence.
The Fronius Primo 'SnapINverters' surged in popularity after the release of the new design nine years ago and are widely regarded as one of the best quality and most reliable residential string solar inverters. While larger and heavier than most modern inverters available today at 21.5kg, the unique snap-in design makes installation and servicing easy.
Perfect for large-scale installations, the fronius tauro commercial inverter 50kw delivers robust performance for industrial applications. With power classes from 50 to 100 kW, these units reduce installation costs while ensuring maximum system productivity in extreme climates.
The intelligent Dynamic Peak Manager algorithm optimizes PV yields at the string level, eliminating the need for expensive module-level optimization components while maximizing energy harvest even in partial shading conditions.
They use an "active cooling system," which includes a fan that may produce a low humming sound, especially during peak operation. However, this sound is usually negligible and unnoticeable in outdoor or enclosed installations. This technology ensures consistent performance and extended lifespan.
The fronius inverter backup power solutions provide seamless transition during grid outages, with the GEN24 Plus offering up to 3kW of emergency power directly from solar panels without battery storage required.
Based on information from Solar Choice's database of residential solar quotes, Fronius has maintained over 50% market share of installers' premium options. While fronius inverter price points position them in the premium segment, the investment delivers exceptional long-term value through superior reliability and performance.
