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. ...

I like the idea of having at least 200watts for power if needed. I pick my campsites on google earth to try to get some sun. But with older state parks in PA, this is hard to find.
You will like it better having 200W portable and 500W permanent :)
Permanent will work on the road, and on open camps, and (a little) under the trees. It still works in leafy shade on a sunny day - poorly - but it works all the time.
You already have 40A controller for 500W permanent. Being MPPT, it can accept 24V panels, they are cheap per watt. Your 2 portable arrays will need 15-20A PWM controller, one for both, it can be found for ~$50. It is not likely that you will have to use both PWM portable and MPPT permanent at the same time, but don't see anything that would make such a pairing impossible.
That's where we're going. A couple of 12V 6x6 170W panels to supplement the 690W on the roof (and often in the shade around here). 1mx1m and 26# each, so portable, but about as big as I want to go for portable. Will run them in series and have one of those cheap Tracer MPPTs on order from China (BFL13 seems to like his).
