    How long does it make AC before the "yellow" light? Does it work with large loads. 
    Try removing DC and repowering. Is battery voltage good, connections good?

    How long have you had this inverter please? It is one of the older ones just after Trace.

    There are people in the US who will repair these but they are repaired from parts from other inverters.
    This model has been out of support from Xantrex, now Schneider for about 19 + years. I am guessing it is a 1997 or so.
