Last year we had a similar problem while we were travelling. Found out that it was a bad inverter.
The T.V, bathroom, closet and outside were all on the inverter circuit on our 2350. We called Xantrex and they wanted to send us a replacement but since we were on the road, it was not an option.
On the way home, we detoured to Elkhart and Phoenix replaced it.
Problem solved!
