So should I add a fuse? Maybe between panel and controller on the hot line? How should I choose the fuse size? Is it a certain size per watt or amp?

Also, with reference to amps and batteries and power consumption. My group 29 has like 125 or so AH. My understanding is that you simply add the amp draw up for all your stuff and that gives you the amps per hour you use. So if you have a stereo and a VHF radio that each draw 5 amps....that will be 10 amps an hour....so I could run them both for about 12 hours before my battery drained correct? The solar panel return amps to the batteries......extending my time. AM I on base here?
