Hi I have a big problem here and need some help. I have a battery bank with 4 series connected batteries (4x12v) giving 48V connected to a charging system designed for 48v (a current source). I need to connect this bank to a 24v DC AC inversor. How is the optimal way (if it is possible) do solve this problem ? We have to consider the fact that the batteries must be discharged simultaneously, because they are charged simultanously (in series). Any suggestion will be welcome.
