Note 2: The recommended fuse types are configured according to the
condition that the input strings are the same.
(d) CPS SC20KTL-DO/US-480 & SC14KTL-DO inverter is equipped with
standard 15A DC fuses. Customers must verify that the appropriate fuses are
used depending on the actual configuration of PV strings.
1） Each independent string of DC input from the PV strings needs fuse
protection.
2） The rated voltage of fuse should be higher than the Max. Voc of each
PV string.
3） In order to keep the output power normal, the rated current of fuse is
generally larger than the 1.56 × Max. output current from the PV
strings.
4） In order to protect the PV strings, the rated current of fuse should NOT
be larger than the sum of the Isc of any two of the PV strings. Make
sure the rated current of fuse is as small as possible on the condition
of normal output power.
5） The following table lists the fuse type, specifications and number
under the rated voltage and power range of 8 strings of PV panels.
Table 3-4 DC Fuse selection
Note 1: The input string size must be the same.
Note 2: The DC fuse protectors of different fusing capacity should be
chosen according to the short circuit current of PV modules. The 600VDC
