looks like the inverter blew a board...I'd try a reset first and see if that brings it back..if it is a magnum or xantrex..call their customer support Tuesday...I've had great support from Magnum..never used Xantrex

Unplug is the first thing. I would be curious what else this electrician may have done.

Otherwise if you cannot get there I would send a mobile RV mechanic.

Wanted is a piece of junk,there is a service rep in Houston that works out of his garage. Had one just shy of a year old and they would not honor there warranty. Was told that they are cheap and the reason you find them in a lot of new units.

He overloaded the unit first, or possible the fan went bad causing high heat which caused the wires to melt. Either way, replace it.

"the inverter is pushing electricity back out to the transformer"

Are you saying that the inverter is trying to feed the power grid? If so, that is your first problem.

How long has he been doing this? We haven't had a hurricane in quite a while. Is he trying to feed power to the house?

Just an update electric company said the neutral was over loaded causing the switchover the fry . The light company also said they are not responsible for the damage to the motorhome. Cost 800 to replace

Still sounds like the inverter was not properly installed or installation was modified by the user.

Either way you need a new inverter and get the wiring checked.

Ok I am going to ASSUME you are comfortable working with COLD (not energized) electrical circuits.

Step one turn it off Unplug from shore. kill generator
Now if there is an inline fuse JUST to the inverter. Pull it. or disconnect 12 volt lead.

Open the 120 volt junction box. Identify the IN and OUT wires and using a sharpie or other marker write IN and OUT on the wires.. Disconnect them from the INverter.

Using any good method (I really do not like wire nuts but they are the easiest

Connect the IN to the OUT.
White to White
Black to Black
and Bare/Green to Bare/Green

Tape all connections to insure safety and security.

YOU NOW have no inverter

Remove inverter to repair shop (NOTE that joining of the Romex really shoudl be done in a nunction box.. Any hardware).

This also assumes you have a sub panel. IF YOU DO NOT get one and run IN to the IN and breakers to the branch outs.


Home is where I park it.
