Collection: Secsun

The Secsun boards in the catalogue cover the whole protection side of a solar installation: DC array combiner boxes for 1 to 6 strings, paralleled or independent, for working voltages from 600 to 1000V, single-phase and three-phase AC protection boards, and interface boards to CEI 0-21 and CEI 0-16 from 20kW up to 1MW, for one or more inverters.

Every board arrives wired, tested and ready to connect: inside are string fuses, surge protective devices, on-load isolators and, in the interface boards, the interface device with its trip coil, the protection relay set to the thresholds the standard requires and the back-up device.

It is the quickest way to finish the electrical side properly, with no loose components to assemble on site.
