Series or Parallel

  • I have a 200w complete kit and another 200w addition, 4 batteries (12V/20Ah). So does all of this have to be connected as parallel?

    From Amazon, details: 

    • [Easy Installation] : The back of the pre-drilled and plug-and-play cables allow quick installation, the kit can be connected in series (24V) or parallel (12V) if you need. What you will get: 2 pcs 100W mono solar panel + 2 set of Z style mounting brackets + 20/30A solar controller + 1 pair of 16.4ft 10 awg solar cables + 1 pair of 2-in-1 connectors.

  • Hi,

    The inverter inside the kit should be a 12V version, which means it needs a 12V battery bank, so both panels and batteries should be wired in parallel.

    Or if you plan to replace the inverter with a 24V version, then the 4 batteries could be wired in 2S2P, 2-serie strings in parallel, as well as the panels.
