DC fuse configuration
CPS SCH100/125KTL-US-600 and SCH100KTL-DO/US-480 inverters are
equipped
with 20A DC fuses. Customers must verify that the appropriate fuses
are installed depending on the actual configuration of PV strings.
1)
Each DC input from the PV strings requires fuse protection.
2)
The rated voltage of the fuse should be 1500Vdc.
3)
The rated current of the fuse is generally 1.56 × short circuit current
from the PV strings, rounded to the next available fuse size.
NEC2017 alternate calculation method may yield a smaller fuse.
The following table lists the fuse type, specifications and number under the
rated voltage and power range of 20 strings of PV panels.
Table 3-12 DC Fuse selection
Note 1: The 1500VDC ADLER fuse series are recommended.
