Inverter Fault Codes on Xantrex Pro XM 1000

Last night I plugged into the back of our inverter a very small oscillating fan to put on our picnic table and it worked fine. At the end of the night I unplugged the fan and stored it away. This morning, Inside the MH, I opened my control center cabinet doors and I pushed my onboard inverter button on the control panel inside the coach just to check and see the charge from batteries. I do this every so often. When I pushed the on button, I saw it blinking EO5 and OL on the display. NEVER have I seen this before.

I downloaded the The Inverter user manual and it was not very helpful.
All it said was, “Overload shutdown, Reduce or disconnect the load. Make sure the load does not exceed the XM 1000/1800’s output rating. Check connection to the load”.

Well the load was disconnected the night before. So I hit the reset button on top of the inverter JIC, and it was OK. I’ve checked to see if there were any tripped fuses throughout the MH and there wasn’t. I’ve reset all the GFCI outlets including the one on the back of the inverter. I measured both house batteries and they are @ 12.78. So I thought I’d try plugging in that same fan in the back of the inverter into that GFCI outlet again to see if that still worked and it does.

So everything seems to be working fine but I have still these flashing fault codes on the control panel inside the coach. What can I do about clearing these codes OR is there something else I should be looking for?

If all else fails , maybe a battery disconnect will clear the system.

OP update...

So we were getting ready to leave our CG and did our usually breakdown method of all our gear, turned everything OFF and then course disconnected from shore power. Then started up the generator, turned on the fridge and headed down the road. Once we got to our new CG, set everything back up, reconnected to shore power and the investor codes we gone and the unit is back to normal. So apparently shutting OFF all power DID reset the system and cleared the codes.
