DC String boxes are made using specific components for the protection and wiring of a single string, two strings in parallel or two independent strings. Furthermore, it is possible to request customized configurations with wiring adapted to the type of PV system.
Pre-wired string boxes with nominal voltage of 600 Vdc and 1000 Vdc are available, with overvoltage protection via type 2 Surge Protective Devices (SPD), overcurrent protection via fuse holders base (fuses included), and isolation via disconnect switches specific for DC-PV1 and DC-PV2 use categories (according to IEC EN 60947-3).
Installation both indoors and outdoors, thanks to enclosures made of insulating material with IP65 protection degree.
