24 volt to 12 volt converter
Looking to run 600 watts of solar to my 40 amp MTTP controller at 36 volts. I have 4-6 volt batteries. So I need to get my 24 volt battery bank down to 12 volts to my Magnum 2012 inverter charger. ...

now, your 40 A controller is too small for a 12 V system unless you intend to throw those watts away.. 40A*12V=480W and you waste 120W ! not an ideal situation.
What are you thinking?
You don't charge at 12v you charge at 14+v
14*40 =560w if he can get it, there is next to zero loss
14.4 or higher is even better
When the batteries are low he will use every amp the solar can make
He probably won't get 600, but he sure will Not be throwing away 120w
yeh.. it's more of an academic response to highlight the CC is maxed out.. I should have worded it differently..
