Aviation output to fuse panel issues

Hello! I’ve been trying to connect my Bluetti AC200P to my fuse block through the 12v25a output and having some issues. Could someone give me some advice please
I purchased the Bluetti aviation cable with the xt60 to Anderson connector then I bought the Anderson to eyehole cable with inline fuse to connect to my fuse block.
I hooked up my puck lights for my trailer conversion and they worked fine. I also hooked a 12v outdoor light to the block and it wouldn’t work. However my indoor lights still work so I know I’m getting power to the block. I also tried to hookup an rv refrigerator and got it running. I disconnected it and later reconnected it and it wouldn’t work. All my connections were good. I then disconnected the refrigerator from the block and plugged it directly into the 10 amp outlet and it worked fine. Also plugged my outdoor lights that I couldn’t get to work on the block directly into the 10 amp and they worked.
So my question is, why are some item’s working and others not on the fuse block?

@DebbieH Is the AC200P connected to too many devices at the same time?
The starting current of the refrigerator will be higher, you can see if the AC200P or your fuse box has reported any error.

No defiantly not too many devices. I only had 4 puck lights that are drawing about an amp and the refrigerator which draws 10 amps max.
I’m getting no error codes.
I’m wondering if my aviation cable is not connected properly to the port. On the connection end of the cable there is a nut that spins. Is that supposed to screw into the port? I thought it was but it doesn’t so maybe it’s not connected properly???

I would check that connection, it is supposed to screw on, maybe the plug is misaligned or not in far enough.

fuses blown on your fuse block? If you are getting power to anything from the block, your incoming power is fine as long as the ring terminal connections are tight. Make sure the wires have not cracked at the ring terminals.
