Along with the growing demand for sustainability, the demand for alternatives to conventional power plants is also increasing. Photovoltaics is by far the largest application area here. Technologies and PV modules are being developed constantly, which means that compatible combiner boxes are also required. Our high-current combiner box contains fuses that are not restricted to 32 A and can handle PV modules with more than 540 Wp.
With our high-current combiner box, you avoid risks when implementing new technologies. Our high-current combiner boxes make it easier to start using the latest technologies, enable a higher electricity yield and bring about lower electricity production costs (LCOE).
Bifacial PV modules have solar cells on both the back and the front 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.
The four new variants of our high-current PV combiner box for bifacial half-cell modules enable a higher current consumption due to the fuse holders used.
Increasing the power of PV panels with half-cut cells leads to a rise in the power per string. The need for higher rated fuses is then pressing, and requires a new approach to system design.
Our new designs of high-current PV combiner boxes offer easy adaptation and time savings for new developments.
