The 1000V
DC
Mersen HP10M PV fuse series are required as
replacement fuses if necessary. Detailed fuse information is
available at http://www.ep-us.mersen.com/.
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 15A fuses with
appropriate ampere ratings, however CPS does not provide nor
stock these fuses.
