Fronius CL 33.3 Delta 3-Phase Inverter

Fronius three-phase commercial inverter with MIX™ technology.

Fronius CL 33.3 Delta Inverter
Several identical power stages in the Fronius CL 33.3 Delta inverter create a compartmentalized system. This well thought out concept was developed to ensure the highest stability in larger multi-kilowatt commercial solar systems.

Multiple power stages operate in the Fronius CL 33.3 Delta inverter accomplishing something great together with MIX™ technology. This combination of several power stages has 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.

Solar system design planning and installation is easy.
The Fronius CL 33.3 Delta inverter was 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 durable NEMA 3R rated weatherproof, powder-coated aluminum enclosure.

Automatic HF Transformer switching
Fronius transformer inverters like the CL 33.3 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.

Technology behind the Fronius CL 33.3 Delta Central Inverter

Fronius MIX™ Technology is the clever combination of multiple power stages means Fronius inverters 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
With MIX™ technology, get the maximum power harvest 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.

Unrivalled stability
The redundant design 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.
