Page 32: Criteria For The Proper Selection Of String Fuses
Criteria for the Proper Selection of String Fuses General The use of string fuses in the Fronius String Control 250/25 US also adds fuse protection to the solar modules. A crucial factor for the fuse protection of solar modules is the maximum short circuit current I of the respective solar module. -
Page 33: Fuses
Application Example: Maximum short circuit current (I ) of the solar module = 5.75 A Example According to the criteria for selecting the correct fuse, the fuse must have a nominal current greater than 1.8 times and less than 2.4 times the short circuit current: 5.75 A x 1.8 = 10.35 A 5.75 A x 2.4 = 13.8 A... -
