I bought 8 12V 200 AH Lithium batteries.  What would be the correct configurations base on that for each equipment?

    Assuming the batteries can be put in series and parallel, Not all Lithium can, depends on their BMS, the inverter is designed for a 48 volt system so 4 batteries in series will give you 200 ah at 48 volts battery bank. If you can parallel the othere 4 batteries for a battery bank of 400 ah at 48 volts.


    Ideally you would have a breaker box with a main breaker for the inverter, and breakers before the charge controller and after the charge controller. It would look something like mine; This is 2 side by side images showing the flow. Solar comes in from the top back of the box, charge controller(s) are to the right, I have 2, and are wired into the positive and negative bussbars.
