Fronius is a recognized Austrian manufacturer of high-quality string inverters. SolarEdge adds the module-level optimization layer that completely transforms system performance.
✓ SolarEdge wins on: modular optimization, SafeDC safety and thermal performanceEach panel operates with its own MPPT. Shading, soiling or different orientation of one module only affects that module. Total system efficiency 98.7%.
Fronius is a pure string inverter. Without integrated optimizers, the weakest module limits the entire string's production.
Integrated SafeDC™: 1V/module automatically. Sense Connect prevents arc faults by detecting connector temperature before failure.
Fronius requires external Rapid Shutdown devices to comply with regulations in some markets. Additional cost and complexity.
SolarEdge inverters at full power up to 50°C. On Mallorca rooftops at 60°C+ in summer, this means more productive hours per day.
Some Fronius models start derating at 45°C. During peak Mediterranean summer hours, power is lost when the sun is strongest.
12→25 years inverter. Optimizers 25 years. 647 granted patents, 527 pending. Local support in Iberia with presence in 14 countries.
5-10 years standard Fronius inverter warranty (extendable to 20). No distributed components with 25-year warranty.
SolarEdge portal: exact output of each module in real time. Remote diagnostics without a physical rooftop visit.
Fronius Solar.web: system and inverter level monitoring. Faulty module requires physical inspection.
Strings of different lengths, multiple orientations, modules from different manufacturers in the same string. No design restrictions.
String inverters require homogeneous conditions. Mixed orientations generate losses without third-party external optimizers.
