If you mean wire the batteries in series (24V) for charging and then disconnecting them and wiring then in parallel (12V) to run the inverter, sure, you could do that. When we say you can't, what we really mean is that you can't do it without re-wiring each time you go from one to the other.

Because when you wire 2 12V batteries in parallel they become a 12V system not a 24V system. You can put 24V to them but while they might charge they also may cook. Usually a 12V battery can except maybe 15V but 24V may be too high. So you can try it but don't expect the batteries to last very longLeave a comment:

Now of course unless the charging complication by the charge controller has an ....
When running 12v accessories (horn, lights, etc..) off of a 36v golf cart they are connected to any 12v combination of 6v batteries. ideally not all to the same 12v bank.
was trying to download a simple diagram picture but wouldn't do it, any document restrictions?Leave a comment:

24v bank supplying 12v power to inverter
I've read here many times that you can't have a charge controller charging a 24v battery bank and then power a 12v inverter...
ok I get that using one 12v or 2x 6v batteries will cause uneven battery discharge and many problems going forward, but....
Why can't I wire the 2 x 12v separately to the inverter so that the crital connections are 12v only.
When we measure voltage on single batteries we pick the 6v, 12v 18v or 24v points in the connection. Why can't I pick the + and - of say each 12v battery and wire it as in parallel to the inverter?
Charges at 24v and powers the inverter at 12v.. just a bit of a wiring mess..
