The Fronius CL 55.5 Delta inverter has a spacious, easy to manage system connection area.

Multiple power stages operate in the Fronius CL 55.5 Delta inverter that accomplish something great together withMIX™ technology. This combination ofseveral power stageshas many advantages: maximum earnings in partial load ranges, high system stability, long service life, and easy servicing.

This model is selectable between 208V and 240V three-phase AC power for utility grid-tie solar system applications.

Solar system design planning and installation is easy.
TheFronius CL 55.5 Delta inverterwas designed with practicality in mind. It can be used for many different configurations due to its planning flexibility. It is also easy to set up due to numerous design details that make installation and connection as simple as possible.

Designed for indoor and outdoor installations.
This inverter has a well designed durableNEMA 3R ratedweatherproof, powder-coated aluminum enclosure. Fronius CL inverters are tested and approved to operate in temperatures up to 122°F.

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 comprehensiveFronius DATCOM system, you can set up a complete monitoring system including extensive data recording, analysis, visualization as well as remote monitoring.

Fronius CL 55.5 Delta Central Inverter Review

Unique system design with the Fronius MIX concept.
Multiple power stages operate in the Fronius CL 55.5 Delta inverter. Fronius MIX™ Technology is the clever combination of these multiple power stages that allows Fronius inverters to always achieve maximum yield, even with partial-loads. This is due to the unique Fronius Master Inverter X-Change system (MIX), a development of the classic master/slave principle. How it works: All power stages are equal. The “master” is allocated alternately, depending on the operating hours. The result is that loads are applied evenly to individual power stages decreasing operating time on any one power stage.

Maximum efficiency under partial load
混合技术,获得最大的收获out of partial load ranges, e.g. on cloudy days, through a clever combination of multiple power stages in each inverter. The power stages in Fronius inverters divide up the work depending on operating hours and only operate as many power stages as required to efficiently process available power from the PV array. Fronius MIX™ technology provides more yield. Depending on the level of available power, either one or up to all power stages work together. Advantages include higher yield during partial load conditions and significantly reduced operating hours. Read more on ourFronius inverterspage.

Unrivalled stability
The redundantFronius solardesign of their inverters means that even if one power stage fails, the inverter continues to operate, ensuring yields are achieved. In the unlikely event a power stage fails the others will continue to operate.

Longer service life
Depending on the operation hours of each power stage, our inverters decide which power stages run under partial load conditions. This ensures that the work load is distributed equally between the power stages. The result is reduced operating time of individual power stages which increases the lifespan of the inverter.

Fronius Module Manager
Whatever solar panel array you decide on, whether monocrystalline, multicrystalline or thin-film, this inverter always fits perfectly in the system-concept. The "Module-Manager" is software integrated into each Fronius CL inverter that optimizes the earnings of your system in each and every situation. The Module-Manager does a first class job and leads to optimal results.

Simple planning, easy installation
TheFronius CLwas designed with practicality in mind. It can be used for many different assignments due to its planning flexibility. It is also easy to set up due to numerous design details that make installation and connection as simple as possible. The universal compatibility with all solar panels and wide voltage range make this inverter a smart choice for most solar system designs. What makes this inverter even more appealing is the intuitive operation and ease of use, together with its highly informative analyses of system values in every situation.

Intelligent cooling
An innovative ventilation design eliminates dust and moisture from getting into the power stage area. The air required for cooling is drawn in by two fans on the front of the device and passed through a closed channel through the individual power stages. The electronic components never come into contact with the outside air. Inside the airtight power stage a smaller fan ensures uniform cooling. This sophisticated system increases the operational reliability and the service life of the inverter.
