Unique System design with the Fronius MIXTM 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 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.
