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. ...

Mex, this all started with this notion here:
"battery V drop under load is halved on a % basis at 24V. If you have 12V marine batts or AGMs with lower internal resistant this may be less of an issue. But it was a hassle with our 4 GC2s under heavy loads in the 12V configuration."
I am unclear -to say the least- on the V=IR stuff when changing from 12 to 24v, but I am questioning the notion that you can do better for running your inverter by going from 12 to 24v
The idea was to keep the same wiring as before but just swap out the inverter. Then it turns out the inverter low voltage alarm goes from 11 to 22 when the voltage system changes from 12 to 24.
So is he any better off running the 24v inverter with the four batts wired for 24v than before when wired as a 12, as far as hitting the inverter alarm to run the same microwave? --using the same wires as before instead of changing them too might be where I am getting confused--I don't know. Mental block!
So is he any better off or not? Thanks!
