Automatic HF Transformer switching
Fronius transformer inverters like the CL 55.5 Delta use a high-frequency (HF) transformer. The automatic transformer switching function in the produces three efficiency peaks. The result: A constant level of efficiency across the entire input voltage range, resulting in higher yields. Other key advantages of HF transformer technology are a compact, lightweight design, and safety as a result of the galvanic isolation.
Wide input voltage range
Different module configurations are possible: The wide input voltage range ensures high flexibility for system configuration.
Extensive system monitoring
System monitoring is vital for inverters of this size. Using the comprehensive Fronius DATCOM system, you can set up a complete monitoring system including extensive data recording, analysis, visualization as well as remote monitoring.
