My nav equipment runs off of 12V batteries which are only charged by shorepower/charger or the gen set. While underway, would like to run without the genset but with nav equipment so was thinking of adding a 32v to 12v converter. The purpose would be to keep the batteries from running down.

Defender Marine offers a 24v to 12v, 20 Amp converter which will accept a 38v input. Ray marine says my total amp draw would be 30amps with everything on, but I could reduce this by not running both stations. Any opinions on this set-up? Also, is there a problem when the battery charger is on ? ( Have talked with Neumar about a 32v to 12v converter but looking for options).
