I have a simple solar power setup:

• 40 watt panel with built-in charge controller
• 12V marine battery
• 12V power point socket
• 5V USB socket adapter w/fuse

I have had various issues with the power socket. It seems that it may be drawing too much power at times.

Usually it is fine, but sometimes the socket, charging cords, and accessories being charged will get extremely hot, and I have also received an alert on my phone a few times that the charging voltage is too high.

I had a previous socket that was unfused, and one day it started sparking and got extremely hot, and could have started a fire, so I replaced it with the fused socket, but am still having problems.

The fuse did eventually burn out, but before it did, I had these heat and voltage issues several times where it did not burn out the fuse.

Am I missing a component in my system?
