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"
I am not understanding this at all. I posted earlier how his 600w array would work out. (goes here after I do some computer stuff)
you don't understand this because your estimate of panel watts assumes panel heating. I can tell you that there are situations/locations at full sun insolation that will max a panel out. been there, done that. now, I'm not saying this is common, but it does occur and should be taken into consideration.(certainly in my business). one other thing, it's also not a good idea to run a CC at max I too long and too frequently.
