Hello Gunboatbay,

You should be able to achieve this by leaving your older system as is and connecting the new inverter to it's own negative and positive terminals. So take a look at the way the old one is set up and do the same for the new one but on it's own terminals.


Hope that helps!

hi

in theory, you can tap into the 12 volt part of your 24 volt battery bank, however, the uneven draw will probably wear down those batteries faster than the other two. i do not recommend it.

Thanks for the help and comments. I guess I'm just too electrically illiterate to understand what you're implying about wearing down the batteries that I would take the 12v from. I always thought that in a dc power system that there would be a power flow from a source of higher potential to a lower potential. That being the reason that charging systems output are higher than battery voltage (e.g. an automotive alternator output is about 14v to insure positive potential flow to a 12v battery). Using this simple logic, I just assumed that the potential of the batteries in my battery bank would tend to equalize one another (assuming they're healthy batteries) and not cause any strain on the two I'd be using. So, help me here, what's wrong with my simple logic??
