im trying to go from the batteries 24v to the 12 volt dc distribution about 8 feet. Right now there is 12v batteries with i think is 6awg, car battery size wire, going from the batts to the dc panel. I found a dc to dc converter that is rated to do 24V Step Down to DC 12V 30A 360W. I have replaced all the light with LEDs from the crap incandescent bulbs.
