Fronius CL 44.4 Delta Commercial Grid-Tie Inverter
Solar inverter for larger commercial solar systems.
The power stages can be easily installed and removed from the CL 44.4 Delta. There is plenty of space in the generous connection area.
Multiple power stages operate in the Fronius CL 44.4 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 44.4 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 44.4 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.

Fronius CL 44.4 Delta Central Inverter Review
Unique system design with the Fronius MIX concept.
An important advantage of having a Fronius CL inverter involves the exclusive MIX™ (Master Inverter eXchange) concept. An inverter becomes significantly more efficient with a DC loading of 25 or more percent of the nominal rated output. Many inverters only have one power stage, becoming less efficient during low sunlight hours.
Simple planning, easy installation.
Integrated grounding option.
