How can this system work...
(OP)
Dear all!
A simple problem (it's not a homework I promise!).
I have
4 x 12V 85Ah batteries.
1 x 12V 85W solar panel
2 x 12V solar charge controllers
1 x 24V solar charge controller
How can I power a system with 24V night and day assuming the power consumption of the system is not draining much power. I unfortunately cannot change the solar panel.
Thank you in advance, and looking forward to hearing from you soon!!!

RE: How can this system work...
A scheme that switches the charge controller output back and forth between the two two-battery banks in parallel, about every 5 minutes, all solar day, would be needed.
Otherwise use a (new)step-up charger that can take the 12V from the panel and and charge a 24V battery bank. Or procure another identical panel and use one panel to charge one battery and the existing one to charge the other battery - each using one of the two existing 12V charge controllers.

RE: How can this system work...
do we assume the 85w solar panel is enough to power your 24v load? if so, do we assume avg load is about 30watt or 1.5amp #24vdc?
then use 1 batt, 1 12v charger, and 1 12v->24v converter like:

or give more details :)

I will try the step up transformer! I hope it works!!!
