About Fronius

Founded in 1945 in Pettenbach, Austria, Fronius has over 75 years of experience in welding technology, battery charging systems, and solar electronics. The company's solar division has been at the forefront of inverter innovation since 1992, developing technologies that have shaped the modern solar industry. Fronius inverters are manufactured in Austria and exported to over 100 countries, with a reputation for quality that rivals German engineering standards.

Fronius is consistently ranked among the top inverter manufacturers globally, with particularly strong market share in Europe and growing presence in North America. The company's commitment to quality, innovation, and customer support has made them a preferred choice for premium residential installations and commercial projects where reliability is paramount.

Primo Series: Residential String Inverters

The Fronius Primo series is designed for residential grid-tie solar installations, offering power ratings from 3.0 kW to 15.0 kW. Key features include:

• 98.6% peak efficiency with 97.9% CEC weighted efficiency
• Dynamic Peak Manager for advanced shade handling and optimization
• Integrated Wi-Fi monitoring with Fronius Solar.web platform
• SuperFlex Design with multiple MPP trackers for complex roof layouts
• Lightweight, wall-mounted design with snap-in installation
• Active cooling system for optimal performance in hot climates

The Primo's Dynamic Peak Manager actively searches for the global maximum power point, even under partial shading conditions. This advanced MPPT algorithm can increase annual energy yield by 5-10% compared to standard MPPT inverters in shaded installations, making the Primo an excellent choice for residential roofs with chimneys, trees, or neighboring buildings.

Symo Series: Commercial Three-Phase Inverters

The Fronius Symo series is designed for commercial and small utility-scale three-phase installations, with power ratings from 3.0 kW to 24.0 kW. The Symo shares the same advanced features as the Primo but adds three-phase output capability, making it ideal for commercial buildings with three-phase electrical service. Symo inverters can be paired with Fronius Smart Meter for advanced energy management, including self-consumption optimization and zero-export control.
