Not generally a good idea to pick 12 volts off a 24 volt battery except for very low current demands.

A 24 to 12 volt converter is the preferred option.

Also possible to use such a device in conjunction with a charge splitter to charge a 12 volt battery directly from the 24 volt alternator.

See http://www.dg2k.co.uk/XTRACT-appl.htm for one idea

A good solution, if you have space etc, is to instal a separate 12v battery, and a separate alternator. That way your 12v and 24v are completely separate. That's what I did with my previous boat.

My boats domestic electric system has four large 6V batteries joined together to give 24V. The switch panel is mainly 24V with one small section ( Four Switches ) that is 12V,how can I add another 12V switch panel to fit new toys ? I would be grateful for advice.

[/ QUOTE ]Where is the 12V from the existing small section derived from? From its own 12V battery or the mid-point of the 24V battery? What load are you taking from the existing 12V rail? You will need to estimate how much load you think you want for the new toys before deciding how to go about the second 12V supply.

I suspect you meant to write that to ferroboat (OP) and not to me? /forums/images/graemlins/smile.gif
