12V DC 115A to 24V DC...

Dear All,

Need some advice how to find a suitable solution for the following:

Have a 12V 115A alternator however I need to charge a 24V battery bank. HavenĀ“t been able to find any DC Voltage Converters 12V->24V managing 115A. Any ideas anyone ?

an alternative - not very effective one - is to go via an inverter 12V -> 230V -> 24V...

Newmar makes all kinds of converters. Pricey!!! With the amount of current you have you could afford some conversion loss.

Carl, if the batteries are separate 12 volt batteries, you could disconnect them, then fully charge each at 12 volts, then reconnect at 24 volts. A little bit of work, but could save you the cost of a converter. Or else change over to a 12 volt setup, new batteries may be cost effective over a converter.

To be honest the "Best and Safest and Easiest" thing to do is not use the 12 volt alternator, but use a 24 volt alternator. There are a few on e-bay. One of my systems has three 24 volt 1500 amp hour battery banks. I am building a charger using a small engine about 14 to 18HP using a 24 to 28 volt alternator with no less then 120 amps output. Trust me you wiring problems will be much easier and the system will be a lot safer using the correct voltage alternator.
