UL listed, 1000V
DC,
20A, 10.3x38mm cylindrical, PV fuses from the
following manufacturers are recommended as replacement fuses when
necessary: Sinofuse or Mersen.
The touch safe fuse holders and wirebox internal factory wiring are
designed to accept either 15A, 20A, 25A, or 30A rated fuses. The larger
rated fuses may be required for combined input strings; for example,
when Y branch connectors are used with DC field wiring to reduce PV
source circuit home runs. CPS allows replacement of the factory
installed 20A fuses with appropriate ampere ratings, however CPS
does not provide nor stock these fuses.
NOTICE:
When installing replacement 25A or 30A fuses, these fuses may not
be installed in adjacent fuse holders. An empty or unused fuse
holder must be positioned between each 25A/30A fuse within each
MPPT.
When Y branch connectors or harnesses are used with DC field
wiring to reduce PV source circuit home runs, the Y-Comb Terminal
Block may be used as an optional accessory. Refer to section 9.3
for further detailed information.
Use of fuses from other manufacturers or incorrectly sized fuses
can cause either equipment damage or create an unsafe working
condition. Any damage resulting from use of incompatible fuses is
not covered by the CPS warranty.
NOTICE:
Note 1: The recommended fuse values are configured based on
the condition that the input strings are the same (module type and
length).
Note 2: The temperature rating of the fuse holder terminals is
(90°C).
