Fronius CL 60.0
SmartGridReady The major advantages of the Fronius CL:

  • Unique system design with the Fronius MIX concept
  • High-yield power electronics
  • Intelligent cooling
  • Simple planning and easy installation
  • Comprehensive system monitoring
 

Overview


Unique system design with the Fronius MIX concept.
15 power modules operate in the Fronius CL 60.0 accomplishing something great together. This combination of several power modules has many advantages: maximum earnings in partial load ranges, high system stability, long service life and easy servicing.


Highest partial load efficiency.
15 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.


Unsurpassed reliability.
The Fronius CL creates a redundant system because it integrates several smaller power modules that work together. If one power module should fail, the others simply take  up the slack. In comparison: when the power module fails in monolithic systems, the entire system stops operating and this leads to considerable loss of earnings. The Fronius MIX concept ensures that the inverter remains in operation even when there is a defect in a power module and this helps to lock in your earnings.


Long service life.
The control unit automatically calculates which power racks and how many will be turned on and off in partial load operation using the respective operating hours of the power modules. This helps to equalize the work load on the PC boards. This also decreases the operating hours of the individual power modules thus increasing the service life of the inverter.


Fast service option.
When service is required, power modules 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.

Equipment features


Simple planning, easy installation.
The Fronius CL was 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.

Wide input voltage range.
Different module configurations are possible: The wide input voltage range ensures high flexibility for system configuration.

Integrated grounding option.
The Fronius CL is well-equipped should modules have to be grounded whether positive or negative. Simply remove the interior grounding holder and insert the fuse.

Optional exhaust air guide.
If the Fronius CL is set up in a closed area, the exhaust air can be channeled out of the space using a connected pipe to prevent extreme heating of the ambient air. An integrated relay contact can also be used to control an external fan that draws the air to the outside.

Low installation height.
The Fronius CL can also fit into shallow spaces due to its low 183 cm 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 Fronius CL 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.


Comprehensive system monitoring.
Professional monitoring is absolutely required for PV systems of this size. That's why the Fronius CL is 100% compatible with the Fronius DATCOM system for comprehensive system monitoring. The Fronius Com Card as well as the Fronius Signal Card and Interface Card functions are standard device features.

Fronius String Control 250/25.
The customized solution for string monitoring of Fronius CL Central inverters is the Fronius String Control 250/25. For detailed information about this product please click here.

 

Technology


Fronius MIX technology

The cleverly-devised combination of several power modules means Fronius inverters always achieve maximum yield, even when in the partial-load range. This is all down to the unique Fronius Master Inverter X-Change system (MIX), a development of the classic master/slave principle. How it works: all power modules are equal. The „master“ is allocated alternately, taking into account the operating hours worked. The result is that loads are applied evenly to individual power modules and the operating time decreases.


HF transformer switchover

Fronius transformer inverters use a high-frequency (HF) transformer. The automatic transformer switchover facility produces three efficiency peaks. The result: a constant level of efficiency across the entire input voltage range, resulting in higher yields. Other advantages of HF transformer technology are the compact, lightweight design, a high level of efficiency and safety as a result of the electrical isolation.


Fronius Module Manager

The Fronius Module Manager always locates the maximum power point (MPP), even in the case of the more demanding thin-layer modules. The Fronius Module Manager achieves an outstanding MPP adaptation efficiency of >99.9 % in total.


PC board replacement

The foundation of the unique PC board replacement is laid as we develop our inverters, as PC boards can only be replaced if the device has been designed accordingly. This enables our Fronius Service Partners to provide the fastest inverter servicing on the market.


Mounting system

What is special about the design of our devices is the separation of the connection compartment and the power module compartment. Both are fitted separately. The connection compartment and all its cabling is fitted to the wall before the power module compartment is fitted. When servicing is required, the entire inverter does not have to be removed, just the power module compartment. All settings and configurations are thus retained.


Ventilation concept

With the Fronius ventilation concept, the air required for cooling is sucked in through a ventilator and fed over the cooling element through an hermetically sealed channel. This means that outside air never comes into contact with the power module PC board or any other sensitive electronic components. This increases operational safety and the service life of the inverter.
