Inverter Powering Converter No Loop Test UPDATE

Thanks for the info using a WFCO 55amper. It does seem safe to say with three different converters now, that there is an extra draw in amps for making the 12v besides the load's draw, but not "too much" so it can't be handled by the set-up.

The scenario where there is no battery in the RV, just 120v items, including the converter to make 12v, would not be very common of course. But now we know it could be done.
