    and the answer to that question is YES!
    so the other side gets a hole,

    You get random strangers to remove light poles to help you out of a pickle.. How can you call yourself "unlucky"? No, wait, don't answer that..

    Faulty solar controller or faulty connections on the battery side of the controller?

    I assume that the controller knows that the batteries are lithium.

    The battery voltage is all over the place when the solar voltage is constant. I would select a different battery type, eg AGM, to see if the battery voltage is any more consistent.

    Is it that the blocking diode in the solar panel or controller is not working ( or is not there!) , so the panel is taking back all the power from the batteries at night.
    That is what happens with solar unless there are blocking diodes.

    To test , just disconnect your solar controller at night.
    It looks from your voltage trace that the graphs are identical so this looks to be the problem.

    Hi Pedro, do you have anything running off the battery while the solar is trying to charge it?

    The solar voltage is fine except for the last section, where the voltage is all over the place and this could easily be caused by a load on the battery.

    If you have no load on the battery, I would be looking at one of the batteries internal BMS.

    The last graph shows battery voltage dropping then rising for a short while then dropping again while solar voltage is constant, so not at night. Maybe the solar charger's lithuim support is incompatible with the battery's BMS, hence my suggestion to switch the solar regular to a regular battery that can take higher voltage.
