REFUsol 333K

98.5 % peak efficiency

Highest efficiencies guaranteed even with low insolation: the efficiency curve shows an efficiency of more than 98.4 % with a broad MPP range of 575 – 1150 V.

High output and input voltages

The output voltage of 690 VAC enables the parallel operation of several devices on only one transformer and is significantly more affordable and involves less loss than several small transformers. Due to the high input voltage of up to 1500 V, longer strings can be realized, which means less loss with the same power and lower wiring costs.

Reduction of system costs

The high energy yield, easy installation, efficient handling and the possibility of using industrially manufactured standard transformers and components from the wind industry results in a significant reduction of the BOS and absolute system costs for larger PV systems.
