    Your understanding is correct. I am not sure why you had problems
    getting the battery and charge controller to work properly and would
    recommend that you send your project to your distributor for
    assistance.<br>

    there is a fairly generic power conditioning model in the standard
    Electrical library; look at Type175. Depending on what your
    controller does, it may be necessary to write your own component. I
    have had to do this in a number of situations where I had a complex
    master controller that was dealing with a bunch of different input
    sources and loads.<br>

    there are a number of pump models in the TESS Hydronics Library that
    take power as an input and determine flow. Look at Types745, 746,
    and 749.<br>
