XPower 1750 Plus Inverter

Hi,

What voltage is being displayed?

It is more likely the mosfet power transistors have failed.

Disconnect completely by removing the negative cable then let it sit for an hour or two.

Reconnect the negative cable and see what happens.

When I turn the inerter on it shows input voltage but no output and the red fault light comes on. I do not have anything drawing on it and the fault light remains. It would not be caused by thermal shutdown or unit overload. So the only option is that the output is short circuited.
So my question is is there anything like a fuse inside that can be changed or just resistors that have failed?

Not familiar with your inverter but on the assumption that the inverter it wired into your coach and the batteries are fully charged, maybe it is signaling a ground fault?

My input voltage is 13.2 and as I have solar low voltage is not a problem.

Giving that a try right now. I'll post on the results.

Wishful thinking on my part MEXICOWONDERER. Guess it's time for a new inverter.

Red light is unit overload or temp overload, rest button on back

Don't see any button fischer. Would you be able to post a link to where you found that info?

I have been using the Can Tire 3000w for a few years now, but you have to wait till they are on sale (every few months) I also ran their 2000, which also comes on sale in rotation, to do the same work but I fried it (my fault). I prefer the 3000 because it does not have to work as hard to do the same job, and I like the twin DC inputs for easy wiring (twin 3ft #4s, making four wires they also sell there) Each of those is MSW, but runs the microwave no problem.

Found when I searched for xpower 1750 manual. The manual states what the light means
