DC input fuse recommendations
The DC ports are designed for Bussmann PV fuses. The table lists the mechanically
suitable fuses for different DC port options. No mechanical changes are required for the
fuse options.
To use the optional fuses, option P902 is required. This can affect the approvals of the
inverter, especially the UL listing.
If you use the recommended fuse sizes and port numbers, decrease the maximum input
power in proportion to the number of unused ports. The maximum short-circuit current
from the PV array per input is the same even if some of the DC ports are not used.

O = Optional fuse (requires option P902, can affect approvals)
