Lithium not charging on shore power

We had dealership upgrade our 2021 Basecamp 16x to 2 lithium batteries. While traveling and not hooking up we always had 97-100% charge. Weíve been in a campground with shore power and watched the charge slowly go down each day we are plugged in to now 60% after 7 days. Even with being gone most of day and not running anything outside of fridge, I look at my victron app and see power use but no charge coming in. Does lithium only charge and work off grid? If so why is it reducing when plugged in? Do you think the dealership didnít make some needed connection? Granted we are in northwest and itís been a little cloudy. We are low power users and even use a small Bluetti to charge iPads and phones.

The converter should charge the batteries. Check to make sure the breaker for the converter is not switched off as Iíve had that occurs before. Iím sure others will chime in to advise of other ways to see if current is flowing to/from converter.

The solar should charge even if converter isnít unless there is too much cloud cover.

Was the converter ever changed to lithium setting?

Is this a new lithium setup? Has it ever worked to charge from shore power?

Without doubt, you should be able to charge from shore power.

If you have solar, you don’t need a lithium converter. It should charge the battery to 80-85%. Solar will charge it the rest of the way.
In any case you should not be losing charge while on shore power.

If fuses and breakers are good, check output voltage from the terminals on the converter. If those are showing proper voltage, then check for loose connections. A clamp-on amp meter can help diagnose if thereís any current flowing from the converter to your panel box. If no current is detected, then thereís likely a loose wire somewhere. Mine was on the negative cable where it ties into the negative bus bar for the whole trailer.

Thank you all for information as I was not sure. I will take it back to dealership to fix but I know now what it should do. Back on road and off grid and on first day of travel even with clouds and rain charged back from 62 to 73% so know the solar charging works.

Ditto on the loose wire check. Found one when the dealer installed the first 2 Li batteries and 2 loose wires when they installed the 3rd. Needless to say, we were not happy as we paid the Airstream premium for the Battleborns and got less than premium service. All are working well now that the problem is fixed so glad we made the upgrade. Also, ended up switching from a WFCO "AD" that wasn't auto detecting to a Progressive Dynamics and that significantly improved the charge speed whether on solar or shore power.

How could the progressive dynamic converter improve the charge speed from solar?

The converter has nothing to do with the solar. There is a separate solar charge controller responsible for that.

Thats why I questioned this post. There are lots of folks that are new to this. I would hate to see someone replace a good converter for the wrong reasons.
