    For 24 volt charging:
    Eight (8) 100W, 12V panels.
    Wire four pairs of two 100W panels in series. Now you have four "24 volt 200 Watt solar panels". Wire pair #1, pair #2, pair #3, and pair #4 in parallel and connect to the TrakMax 40A Controller.

    For 12V charging:
    Four (4) 100W,12V solar panels to one TrakMax 40A.

    Note: Multiple TrakMax Controllers can be wired to the same battery bank in parallel for larger systems
  2. I have 10, 100 watt panels on mine 5 series 2 parallel, I bring down around 80 vDC give or take a little at around 8 - 10 amps Depending on Time of day and how much sun is hitting them, using the TrakMax 30A MPPT Controller works for me with no issues.

    Thanks for the update.
    What type of charging current are you seeing from the MPPT controller using this configuration?
