Inline fuse for solar panel.
The second fuse between your solar panels and charge controller is a little bit different to figure out.
In this case the battery wires and ac dc inverter will be safely disabled by the fuse.
Fusing solar panel arrays wired in parallel.
If the panels are connected in series the voltage of each panel is added but the amperage stays the same.
The size of this fuse is dependent on how many solar panels you have and how they are connected series parallel or series parallel.
Now in the case of 3 panels in series and 4 strings in parallel if one string shorts the max amperage to short is 39 12 which exceeds the 30 amp max current rating of the 10 awg wire.
It is not mandatory to have fuses for your system to function properly.
However we do recommend to add fuses to prevent any mishaps.
This means each series needs a fuse breaker placed in the combiner box as shown here.
