Unique system design with the Fronius MIX concept

Nine power modules operate in the Fronius CL 36.0 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

Nine 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 vcomparison: 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 customised 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.


High-yield power electronics

The Fronius CL was designed for continual high performance. The clever combination of automatic transformer switching, the precise Fronius Module Manager, the innovative ventilation concept and the advantages of the high frequency transformer technology make it one of the highest yield inverters of its class.

Automatic transformer switching

The Fronius CL provides constant, high efficiency over the entire input voltage range. This is because Fronius inverters have three efficiency peaks due to automatic transformer switching. In comparison: Devices without transformer switching only have one efficiency peak. The efficiency then decreases steadily with an increasing input voltage.

Exact MPP tracking

The Fronius Module Manager always finds the exact maximum power point (MPP). This is true even with the more demanding thin-layer modules. Overall, the Fronius Module Manager is able to achieve an outstanding MPP adaptation efficiency of 99.9%. This ensures that the maximum yield is obtained from every ray of light.

High-frequency transformer technology

High performance with low weight and a compact design: The use of proven high-frequency transformer technology produces excellent performance results. The Fronius CL uses galvanic isolation, which meets the strictest safety standards worldwide.

Intelligent cooling

An innovative ventilation design eliminates dust and moisture from getting into the power module 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 racks. The PC boards never come into contact with the outside air. Inside the hermetically sealed power module, a smaller fan ensures uniform cooling. This sophisticated system increases the operational reliability and the service life of the inverter.
