• table housing made of glass-fiberS reinforced polyester • ndoor and outdoor installation I possible thanks to IP54 degree of protection • an be operated at ambient C temperatures of −25°C to 60°C and at altitudes of up to 4000 m above MSL • asy to install thanks to its compact E structure and low weight • ntegrated DC load-break switch I for ultra-high safety • or PV array voltages of 1000 V F and 1500 V • ollection and safeguarding of 16, C 24 or 32 strings for flexibility during the system design phase For safe collection of all strings in the PV field The boxes can be installed quickly, safely and easily both indoors and outdoors thanks to their compact dimensions, while their robust enclosure guarantees durability and reliable safety in the PV field. The SMA String-Combiners with 24 and 32 string inlets are fitted with two cable outlets per pole as standard and cover – just like the Combiner with 16 string inlets – a sealing range of 17 to 38.5 millimeters. Cables with cross-sections of 70 to 400 m
