-Fusing position
The combiner box has built-in fuses for each string, so there is no need
to add extra fuse in between the solar panels and combiner box, neither
from the combiner box to inverter.
Even though the hybrid inverter has built-in fuse, it’s better to add one
fuse in between it and the battery bank. For a 24V 3500W inverter, the
current it can take from the battery bank should be about 146A, so a
180A fuse is recommended.
