Is now the time for a move to 48 volt DC systems?
r as long as I’ve been covering marine technology, I’ve heard consistent talk of a move to a higher voltage than the defacto 12-volt standard. 48 volts is often cited as the sweet spot between efficiency, safety, and reduced weight. But, why make a change? 12-volt has served boats well for a long time, why change? Let’s take a look at the reasons for a change and perhaps some reasons to move cautiously.
