Solar Charge Controller (fuse?)

Does a solar charge controller have an internal fuse that can be blown? If so, can it be changed out like a fuse in an inverter?

I purchased a new charge controller, all is connected properly but no LEDs are lit. My inverter is working fine, it has a display and it shows no charging taking place.

get that solar 30 wet once in the rain and you will have detroyed it and it will act just like you're describing that unit has to be mounted inside and I don't believe there is a fuse mounted inside of it I've opened mine up and found it to not be salvageable
