Converter constantly cycles b/w battery & shores

Howdy,

My first post and second trip in my 2019 Rpod 179.

I have a progressive industries internal EMS installed. The code it’s displaying when I am plugged into shore is E0, so everything should be fine with the shore power, but the converter keeps cycling between the battery and the power.
When on power the fan turns on in the circuit box and the battery goes to 12.4. When the fan is running the battery goes to 13.5. Each time the battery indicator says it’s full.

Other things
The microwave only works on shore power, so it beeps whenever the converter switches.
The Dometic fridge keeps cycling so I turned it to propane and the warning indicator keeps flashing. I’ve confirmed that the propane is on and there is propane in the tank.

CraY thing is that I lived in this thing for a week plugged into my house prior to this trip and everything worked perfectly. Pulled up to the RV spot tonight and nothing seems to be working right?

Any thoughts or suggestions?

Not sure what you mean by the converter cycling between battery and power? The converter will charge the battery when it’s on shore power, and does nothing when you’re not on shore power.

One thing I’ve noticed with the WFCO charger is that at a relatively low battery state of charge it can get into a cycle in and out of bulk power mode. It senses low battery voltage so goes into bulk power mode, at which point it puts out its max current. The high current makes the battery voltage rise until the charger drops into absorption charge mode. Once in absorption mode the current falls off and the battery voltage drops, sending the charger back into bulk charge mode, and so on.

If you think that might be your problem you can remove as much load as possible from the battery and let the charger recharge it fully, then see if the problem corrects itself.

It's not the 110 volt loads that is causing the converter to cycle, it's probably the 12V loads.

I forgot to mention, Offgrid, I didn’t turn off the circuit for the main or the converter. I left it overnight and flipped them back on today; the same thing is happening.

So, I removed the stereo & microwave fuses for the 12v side as GlueGuy pointed out. I switched the microwave circuit back on and the cycle was still cycling.

The solar charger (I think of it as a trickle charger) has readout staying the battery is 75% full, while the KIB panel that tells me the level of Gray, Black, Fresh, and Battery indicates the battery is full.

Still not sure what to do. Any thoughts?
