• Generator Connection Boxes and Columns

DC combiner boxes "DCBs"

Connect the individual solar module strings in a photovoltaic installation in parallel and connect them to the inverter using larger cable cross sections through a string.CB generator connection box or a string.CC generator connection column. The integrated string.bloxx allows precise monitoring of the DC side of photovoltaic installations independently of the inverter.
