Xantrex XS400 Problem
This inverter is installed in our 2006 30' IB and was installed by the factory. It runs one outlet located in the over the cab entertainment center. The inverter is located under the refrigerator mounted on top of the battery box. House batteries are two Trojan T145 6v. We have a remote off/on switch in the entertainment center.

Yesterday after running the generator I found that the GFCI outlet built into the inverter had tripped. No sign of water problems in the area. Resetting the switch did not get power. I turned on the generator again and saw power come on at the entertainment center only to hear the GFCI trip again and shut the power off within 10 seconds. I reset the outlet while the generator was on and got power to the EC outlet and it continues to work without the generator running.

This inverter has a built-in bypass and a power cord. When you are plugged into a power pedestal or turn on the generator you get AC power at the EC outlet bypassing the inverter.

Does anyone have any ideas on why the GFCI is tripping? Even though it has never been used I assume it could just be failing. Also, since I don't really see a need for it to be plugged into power I unplugged it and will use the inverter to power the outlet.

I seem to recall this is not the first issue with your inverter. In another post, it seems that the inverter may not be grounded. Why that is causing a problem not and not have caused a problem 8 years ago is beyond me. Ground it.

GFCI's do not last forever. I replaced two in our home this spring that were acting flaky.

The brand of an inverter is not important to me. You will find most are built in China. You may notice that one priced twice as much looks identical to another one.
