Fronius DC Connector Kit 42,0201,4480
Fronius, Primo/Symo, DC Negative combined input buss bar, 42,0201,4480
The DC connector kit allows you to combine multiple PV strings at the array and connect them to the inverter with a single pair of conductors. When using a combiner box at the array, using fewer conductors will help save money on installation. Only strings with an even number of modules should be combined, and the inverter's MPPT settings should be changed. The copper "comb style" bus bar is encased in plastic to minimize safety issues in the link area, and the DC connector kit can handle wires from 10 to 2 AWG.
