Why do you need to install the in-line fuse between the battery and solar controller?

The solar controller has provided the internal electronics protection, also built in the temperature protection, which is to protect the safe operation of the solar controller, but when the solar controller is connected to the battery via the external cables, there are some potential failures.

For example: the wrong operation or wrong connection, the wire aging, the connection point loose, etc; if these failures are caused the battery shorted (the positive polarity and negative polarity shorted circuit), it may bring a serious risk, even fire, since the instantaneous short-circuit current is very large (hundreds ampere even over one thousand ampere), it may be hurt to the human safe, so, built in an in-line fuse on the cables will avoid the risk by some abnormal failures.
