An IOTA 55 converter. It has everything you need and will grow into. The Company is great and a real person is always there to answer any question.
A Blue Sea fuse box....automotive type fuses are great. Can get one with a voltmeter if you like. Use Ebay for best price.
A good quality deep charge type battery...I got Lifeline...but, I think they are to expensive.
A battery disconnect. Again Ebay for a PERKO or Blue Sea.
PS....as mentioned above on the circuit breakers. Beware of a major recall...safety warning...on circuit breakers.
BIG ITEM....put the fuse box where you can see it and get at it. This goes for anything you do with systems in the Caravel
