Fronius CL 48.0 WYE277 3-Phase Commercial Solar Inverter

Commercial grid-tie inverter with 277 VAC output.

CL 48.0 WYE277 power stage in PowerRack
High performance power stages are easily installed in the PowerRack of the Fronius CL 48.0 WYE277 inverter.

Multiple power stages operate in the CL 48.0 WYE277 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.

Solar system design planning and installation is easy.
Fronius CL inverters are designed with practicality in mind. They can be used for many different configurations due to their planning flexibility. They are 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 for dependability year-round.

Automatic HF Transformer switching
Fronius transformer inverters like the Fronius CL 48.0 WYE277 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 48.0 WYE277 Central Inverter Review

Unique system design with the Fronius MIX concept. 
Multiple power stages operate in the Fronius CL accomplishing something great together. This combination of several power stages has many advantages:  maximum earnings in partial load ranges, high system stability, long service life and easy servicing. These identical power modules divide up the work in the MIX concept. The individual power racks are turned off and on automatically depending on the insolation power. This ensures that the load is optimized and yield is always at maximum – even while raining, when cloudy or at dusk. 

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 commercial grade 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 and use due to superior flexibility.
The Fronius CL 48.0 WYE277 inverter can be used with many different configurations due to its planning flexibility. This is ideal when considering different types of solar modules or solar system expansion in the future. The wide input voltage range of this CL series inverter makes different module configurations possible. This wide input voltage range ensures high flexibility for system configuration. 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.

Integrated grounding option.
The Fronius CL is well-equipped should modules have to be grounded whether positive or negative. Simply change two wires and a software paramater to change from negative to positive grounding.

Low installation height.
The Fronius CL can also fit into shallow spaces due to its low 72 inch height (with base). This compact design is achieved by its three-row arrangement of power modules in the inverter.

Low installation weight.
The power racks can simply be removed for installation. This reduces the weight of the CL 48.0 WYE277 inverter and makes the housing easier to move. The racks can then be re-inserted and the inverter can begin operation immediately.

Generous connection area.
Sufficient space is available for connections and cabling with large cable cross sections. This makes installation simpler and much easier.

Fast service option.
When service is required, power stages can be removed and replaced easily via the plug & play principle and drawer design. This ensures the highest serviceability and the fastest reaction times on the market.

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.
