Compact and durable solutions for bifacial half-cell modules

Bifacial solar panels have solar cells on both the front and the back of the panel. This allows the solar energy to be collected on the back of the panel and increases the energy yield of the solar energy system.

Our four new PV-DC combination boxes for bifacial half-cell modules allow a higher current consumption due to the fuse holders used.

Space optimized and higher reliability

Space optimized and higher reliability

Increasing the power of PV panels (mono and bifacial) with half-cut cells leads to a rise of current in the strings. The need for higher rated fuses is then mandatory and requires a new approach to system design.

Our new designs of PV DC high current combiner boxes offer easy adaptation and time saving for new developments.
