    Temperature too high?

    http://www.redarc.com.au/images/uploads/images/Solar_Regulator_Instruction_Manual.pdf


    Digital tube displays
    “H” with red slowly
    flashing
    Too high
    temperature of
    controller
    When heat sink of the
    controller exceeds
    85 ℃, the controller will
    automatically cut input
    and output circuit. When
    the temperature below
    75℃, the controller will
    resume to work
    Notes: No LED indicator.
    Measure battery voltage with multimeter.
    Min.6V can start up the controller.
    Notes: No charging status LED indicator with normal
    connection. Measure the input voltage of solar module,
    the input voltage must be higher than battery voltage!

    Have you tried disconecting it & reconecting (in the correct sequence) again?
