Note 1
：
The DC fuse protectors of different fusing capacity should be
chosen according to the short circuit current of PV modules. The
600VDC Littelfuse KLKD fuse series are recommended. The detailed
information is available for customers to find and download from
The recommended fuse types are listed in the following table:

Note 2: Concerning the current share of fuse for each DC input string, 1
or 2 DC input strings are NOT recommended. If it has to be, we suggest
that the DC input wire be connected to the inverter without DC fuses as
follows:
