No power from inverter WFCO WF-5110

I have 2018 Classic 30RBT and my inverter is not working. So the fans on the inverter are on and the display shows the correct incoming voltage, outgoing voltage, and amps being drawn. The troubleshooting docs say that if the amber/yellow light is on it should be working but if there is no power replace it. I'm hoping there is something else to try. None of the outlets have any power. It's a WFCO WF-5110 series with the red plastic cover. Thanks for the help.

Did you ever figure out your inverter problem. We bought a used 2015 27FBQ Fly Cloud and experienced the same problem on our first trip this week

Do you have the manual? I found a manual that should be similar and shows a circuit breaker on the back side of the unit.

Have you checked that?

My problem is (was) intermittent. The inverter is running perfectly (though the fan is bothersome) in the driveway right now. All day in fact.

Earlier this week though .... stayed at a park with high voltage (129VAC). The hardwired surge protector would not allow us to connect to shore power, until the voltage dropped below 128 V. Even then, the pedestal power was 124 VAC. I suspect the converter was over charging the batteries, since the battery voltage was 14.4 VDC, which is much higher than the optimal 13.7 VDC. The excessive battery voltage may have caused the inverter to stumble. The owners manual is not particularly useful, especially the troubleshooting flowchart. Their flowchart said "Replace the inverter"

I called Power Surge to see if there is a way to calibrate the high voltage limit and they said "NO". The engineer suggested buying a Variac or autotransformer to dial the shore power voltage down. We will test my intermittent failure theory once my Variac arrives since I can replicate the overcharge condition.

So here we are 1 month later. My 20 Amp Variac works well enough since we have no need for the AC or Heat Pump.. I installed a remote monitor screen for our Progressive Industries internal surge protector and saw the device would not power up due top over voltage. The voltage was high (again)! So i plugged in the Variac. I set the Variac to 125V output so the inverter kicks out still as the voltage in the park still bounces around. The Variac seems to work well but it is outside in a plastic box so I need to fab up a better - vented - solution. It will be part of my kit going forward.
