Hi Dan, If you have not made ANY changes to the inverter and it operates fine with the 1000 watt, it must be the Honda 3000 output.
The reliability of Magnum has been consistent and outstanding so I doubt it is the problem. I have seen them fault out on over frequency, over voltage and under voltage but always return to normal operation after the power quality is within spec. Bottom line is I would not be looking at the Magnum as the problem UNLESS a parameter or wiring was changed.
