  • 12v panels to 24v?

    Somehow I am thinking to much and have a quick question. I have 6-100w panals and I want them to have 24v output. I am now confused on how to wire them to end up with 1 pos and 1 neg to put to my controller.

    I think I answered my own question, the panels would be the same hook up as the battery setup

      Use a MPPT Controler and wire them 2 x 3. If you use PWM you have no choice but 3 x 2

        2 x 3 is what others would write as 2P3S, right? Two strings of three panels?
        Then 3 x 2 = 3P2S, there parallel strings of two panels each?

          Correct.
