Quick answer: The C350-SZM is a ribbon busbar bend cutting machine for PV module assembly. It produces up to about 30 pieces at a time, working with bends up to 8.0 mm and lengths to 450 mm with a 100 mm allowance, and is specified for module lines from 5 MW to 1 GW. Busbar bends are the formed interconnect pieces that route current from the end of a string out to the junction box and around the frame edge. A bend formed to the wrong radius or length does not sit flat on the cell or the laminate, and the resulting joint is stressed from the moment the module is built. Cutting and bending on one machine keeps the formed piece consistent with the cut length, which is what makes the busbar sit without pre-load.
