Solax - Increase Battery storage - beyond 3 Units

I have a Solax 5Kw inverter and 3 x 5.8KW battery - Single Phase. As per Solax, I cannot add another battery as max 3 is a limit. I want to add an additional battery(4th) (slave). Is there a way I can control automatically disable (Ras pi) one battery and enable another such that the limit of 3 is not breached? or there exists another alternative to increased battery capacity.
Thanks

    Without a full understanding of the system, I think the answer is going to be "no".
    Switching a fully-charged battery into a systwem that contains partially-discharged ones strikes me as unwise.

    As I pursued to understand if I can add additional batteries  - I read the solax inverter setup guide - It is possible to have a Slave Inverter and batteries. The master and slave inverter are connected by CAN CAT7 cable.
  • You could contact solax they reply sometimes... how did you get all those batteries im still waiting on my second  :D

    I believe you can add 3 slaves to one Solax Master (i.e. with Battery Management Unit) so 4 batteries in total.
    See 614.00425.06 T58 User Manual.pdf (solaxpower.com) p29 section 4.6
    You need to power everything down, plug in the additional cables, and move the dip switch to the appropriate position.
