Under Voltage & Discharging

Our trailer has only one 180W panel.
That day the sun was directly shining on the panel. As you can see, the battery is not being charged even though PV is showing 21v.
The charging amps are 0 in this attached screenshot.
Thankyou for your information, if I apply what you said to my data, it looks like my battery is not charging also and the solar is 22.7v. How will you end up getting yours to charge? My RV is not undercover, but if I do not turn the battery selector to off the battery goes down to under voltage like yours. My last RV had a victron 100/30 and I never had to shut the battery switch off and the battery was always up at 100% SOC. Does the discharging status in your app always read "red"? and what does that mean? It would be helpful if I had your screen shots to compare, but I do not really understand the numbers very well. I wish there was a manual for the app. If you have any thoughts on these screen shots I am all ears. Thanks again.

Today at 1043 hrs, the Furrion app is reporting an under voltage and there is no charge being applied to the battery. The shunt meter is reporting a .226A discharge (parasitic 6AH in 24 hours.
If I turn my Battery switch off, my battery seems to hold a charge at least for a while and not go to under voltage reading. Do you have to shut your battery switch to off to keep the battery up?
 
I haven't turned the battery switch off as I am trying to establish how much power is being drawn out of the battery bank.

The solar system is not keeping up to the rate the fridge and other parasitic consumers are using..

I have found that the parasitic draw is 0.225 A. Over a period of 24 hours, that is 6AH from 100AH available.

My previous trailer with same panel wattage covered that 6AH discharge easily.

The present system fails to provide any power to the battery bank, even though the solar panel is showing 21v. The amps are showing 0A.

Yes, the battery would have to be switched off.

The parasitic draw in our Imagine XLS 21bhe is about 6AH over 24 hours. The solar system should easily cover that. Even though the panel shows 21 or more volts, the amps are showing 0A. The battery is accepting 0A.
It appears to me that our trailer's solar charge controller is faulty.
Though the low voltage fault is indicated with a battery voltage showing 11.8 V, I think the charger output voltage is low triggering the fault.

I'm with SoundSailor. Replace the Furrion junk with Victron.
Amen....went down that path a couple of months ago. Changed out to Victron and no issues. Also on our 303rls ,turning off the battery switch does not shut everything off..smoke,propane detector, even radio had a light on. I installed a shut-off on the negative side of the battery, that shuts everything down.

Another person on here said to go to Victron, solved problem. Sometimes the Furion charger would work and other times it would not. I read people were climbing on the roof and unplugging the solar panels to get it to work...crazy
